Marie Salomea Skłodowska Curie ( KEWR-ee; French: [kyʁi]; Polish: [kʲiˈri]), born Maria Salomea Skłodowska (Polish: [ˈmarja salɔˈmɛa skwɔˈdɔfska]; 7 November 1867 – 4 July 1934), was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. As the first of the Curie family legacy of five Nobel Prizes, she was the first woman to win a Nobel Prize, the first person and the only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two scientific fields. She was the first woman to become a professor at the University of Paris in 1906.She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. In 1895 she married the French physicist Pierre Curie, and she shared the 1903 Nobel Prize in Physics with him and with the physicist Henri Becquerel for their pioneering work developing the theory of "radioactivity"—a term she coined. In 1906 Pierre Curie died in a Paris street accident. Marie won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
Under her direction, the world's first studies were conducted into the treatment of neoplasms by the use of radioactive isotopes. In 1920 she founded the Curie Institute in Paris, and in 1932 the Curie Institute in Warsaw; both remain major centres of medical research.

An alcoholic drink is a drink that contains ethanol, a type of alcohol produced by fermentation of grains, fruits, or other sources of sugar. The consumption of alcohol plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages. Some countries ban such activities entirely, but alcoholic drinks are legal in most parts of the world. The global alcoholic drink industry exceeded $1 trillion in 2018.Alcohol is a depressant, which in low doses causes euphoria, reduces anxiety, and increases sociability. In higher doses, it causes drunkenness, stupor, unconsciousness or death. Long-term use can lead to an alcohol use disorder, an increased risk of developing several types of cancer, and physical dependence.
Alcohol is one of the most widely used recreational drugs in the world, and about 33% of all humans currently drink alcohol. In 2015, among Americans, 86% of adults had consumed alcohol at some point, with 70% drinking it in the last year and 56% in the last month. Alcoholic drinks are typically divided into three classes—beers, wines, and spirits—and typically their alcohol content is between 3% and 50%.

A camel is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The Wild Bactrian camel is a separate species and is now critically endangered.
The word camel is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the llama, the alpaca, the guanaco, and the vicuña. The word itself is derived via Latin: camelus and Greek: κάμηλος (kamēlos) from Hebrew, Arabic or Phoenician: gāmāl.

The average life expectancy of a camel is 40 to 50 years. A full-grown adult dromedary camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump.

Chachalacas are galliform birds from the genus Ortalis. These birds are found in wooded habitats in the far southern United States (Texas), Mexico, and Central and South America. They are social, can be very noisy and often remain fairly common even near humans, as their relatively small size makes them less desirable to hunters than their larger relatives. As agricultural pests, they have a ravenous appetite for tomatoes, melons, beans, and radishes and can ravage a small garden in short order. They travel in packs of six to twelve.  They somewhat resemble the guans, and the two have commonly been placed in a subfamily together, though the chachalacas are probably closer to the curassows.


== Taxonomy ==
The genus Ortalis was introduced (as Ortalida) by the German naturalist Blasius Merrem in 1786 with the little chachalaca (Ortalis motmot) as the type species. The generic name is derived from the Ancient Greek word όρταλις, meaning "pullet" or "domestic hen." The common name derives from the Nahuatl verb chachalaca, meaning "to chatter." With a glottal stop at the end, chachalacah was an alternate name for the bird known as the chachalahtli. All these words likely arose as an onomatopoeia for the four-noted cackle of the plain chachalaca (O. vetula). The genus contains 16 species.Mitochondrial and nuclear DNA sequence data tentatively suggest that the chachalacas emerged as a distinct lineage during the Oligocene, somewhere around 40–20 mya, possibly being the first lineage of modern cracids to evolve; this does agree with the known fossil record – including indeterminate, cracid-like birds – which very cautiously favors a north-to-south expansion of the family.

Rabbits are small mammals in the family Leporidae (along with the hare) of the order Lagomorpha (along with the pika).  Oryctolagus cuniculus includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. Sylvilagus includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit (or bunny) is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration.
Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra incisors.


== Terminology ==
Male rabbits are called bucks; females are called does.  An older term for an adult rabbit is coney (derived ultimately from the Latin cuniculus), while rabbit once referred only to the young animals. Another term for a young rabbit is bunny, though this term is often applied informally (particularly by children) to rabbits generally, especially domestic ones. More recently, the term kit or kitten has been used to refer to a young rabbit.

Salmon  is the common name for several species of ray-finned fish in the family Salmonidae. Other fish in the same family include trout, char, grayling, and whitefish. Salmon are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus). Many species of salmon have been introduced into non-native environments such as the Great Lakes of North America and Patagonia in South America. Salmon are intensively farmed  in many parts of the world.Typically, salmon are anadromous: they hatch in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn. Tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend on olfactory memory.

The African wildcat (Felis lybica) is a small wildcat species native to Africa, West and Central Asia up to Rajasthan in India and Xinjiang in China. The IUCN Red List status Least Concern is attributed to the species Felis silvestris, which at the time of assessment also included the African wildcat as a subspecies.In Cyprus, an African wildcat was found in a burial site next to a human skeleton in the Pre-Pottery Neolithic B settlement Shillourokambos. The graves are estimated to have been established by Neolithic farmers about 9,500 years ago, and are the earliest known evidence for a close association between a cat and a human. Their proximity indicates that the cat may have been tamed or domesticated.
Results of genetic research indicate that the African wildcat genetically diverged into three clades about 173,000 years ago, namely the Near Eastern wildcat, Southern African wildcat and Asiatic wildcat. African wildcats were first domesticated about 10,000 years ago in the Near East, and are the ancestors of the domestic cat (F. catus). Crossings between domestic cats and African wildcats are still common today.


== Taxonomy ==
Felis lybica was the scientific name proposed in 1780 by Georg Forster who based his description on a specimen from Gafsa on the Barbary Coast that had the size of a domestic cat, but a reddish fur, short black tufts on the ears, and a ringed tail.
Between the late 18th and 20th centuries, several naturalists and curators of natural history museums described and proposed new names for wildcat holotypes from Africa and the Near East, including:

Felis ocreata by Johann Friedrich Gmelin in 1791 was based on a description of a wildcat encountered in northern Ethiopia by James Bruce.
Felis cafra by Anselme Gaëtan Desmarest in 1822 was based on two wildcat skins from South Africa's Eastern Cape.

The groundhog (Marmota monax), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. 
The groundhog is a lowland creature of North America; it is found through much of the eastern United States, across Canada and into Alaska. 
It was first scientifically described by Carl Linnaeus in 1758.The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk, land beaver, and, among French Canadians in eastern Canada, siffleux.The name "thickwood badger" was given in the Northwest to distinguish the animal from the prairie badger. Monax (Móonack) is an Algonquian name of the woodchuck, which means "digger" (cf. Lenape monachgeu). Young groundhogs may be called chucklings.The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas. Groundhogs maintain an important role in maintaining many healthy soil in woodland and plain areas. Groundhogs are an extremely intelligent animal forming complex social networks, and understand complex social behavior, form kinship with their young, understand and communicate threats, and are able to work cooperatively to solve tasks such as burrowing. Due to this the Groundhog is considered a crucial habitat engineer.

Table tennis, also known as ping-pong and whiff-whaff, is a sport in which two or four players hit a lightweight ball, also known as the ping-pong ball, back and forth across a table using small rackets. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce one time on their side of the table and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage.
Table tennis is governed by the worldwide organization International Table Tennis Federation (ITTF), founded in 1926. ITTF currently includes 226 member associations. The table tennis official rules are specified in the ITTF handbook. Table tennis has been an Olympic sport since 1988, with several event categories.

The garden strawberry (or simply strawberry; Fragaria × ananassa) is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others.
The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of Fragaria virginiana from eastern North America and Fragaria chiloensis, which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of Fragaria × ananassa have replaced, in commercial production, the woodland strawberry (Fragaria vesca), which was the first strawberry species cultivated in the early 17th century.The strawberry is not, from a botanical point of view, a berry. Technically, it is an aggregate accessory fruit, meaning that the fleshy part is derived not from the plant's ovaries but from the receptacle that holds the ovaries. Each apparent "seed" (achene) on the outside of the fruit is actually one of the ovaries of the flower, with a seed inside it.In 2017, world production of strawberries was 9.2 million tonnes. China was the top producer, with 40% of total production.


== History ==

The first garden strawberry was grown in Brittany, France, during the late 18th century.

A toothbrush is an oral hygiene instrument used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example floss, tape or interdental brushes.
They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums.Because many common and effective ingredients in toothpaste are harmful if swallowed in large doses and instead should be spat out, the act of brushing teeth is most often done at a sink within the kitchen or bathroom, where the brush may be rinsed off afterwards to remove any debris remaining and then dried to reduce conditions ideal for germ growth (and, if it is a wooden toothbrush, mold as well).
Many toothbrushes have plant based handles, often bamboo. However, numerous others are made of cheap plastic; such brushes constitute a significant source of pollution. Over 1 billion toothbrushes are disposed of into landfills annually in the United States alone. Bristles are commonly made of nylon (which, while not biodegradable, as plastic is, may still be recycled) or bamboo viscose.


== History ==
 
Before the invention of the toothbrush, a variety of oral hygiene measures had been used.

In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil.
