Animal experiments and drug safety Scientists say that banning animal experiments would mean either an end to testing new drugs or using human beings for all safety tests Animal experiments are not used to show that drugs are safe and effective in human beings - they cannot do that. Instead, they are used to help decide whether a particular drug should be tested on people.
Siberian Taiga A biome is the type of habitat in certain places, like mountain tops, deserts, and tropical forests, and is determined by the climate of the place. The taiga is the biome of the needleleaf forest.
Living in the taiga is cold and lonely. Coldness and food shortages make things very difficult, mostly in the winter. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment, which is very difficult. Dillon Bartkus Taiga is the Russian word for forest and is the largest biome in the world.
It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. A lot of coniferous trees grow in the taiga. The taiga is also known as the boreal forest.
Did you know that Boreal was the Greek goddess of the North Wind? The taiga doesn't have as many plant and animal species as the tropical or the deciduous forest biomes. It does have millions of insects in the summertime. Birds migrate there every year to nest and feed.
Here is some information about the temperatures and weather in the taiga. The average temperature is below freezing for six months out of the year.
The winters, as you can see, are really cold, with lots of snow. The summers are mostly warm, rainy and humid. They are also very short with about 50 to frost free days.
The total precipitation in a year is 30 - 85 cm 12 - 33 in. The forms the precipitation comes in are rain, snow and dew.
Most of the precipitation in the taiga falls as rain in the summer.
The main seasons in the taiga are winter and summer. The spring and autumn are so short, you hardly know they exist. It is either hot and humid or very cold in the taiga. There are not a lot of species of plants in the taiga because of the harsh conditions.
Not many plants can survive the extreme cold of the taiga winter. There are some lichens and mosses, but most plants are coniferous trees like pine, white sprucehemlock and douglas fir. Coniferous trees are also known as evergreens. They have long, thin waxy needles.Tool use by animals is a phenomenon in which an animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, defense, recreation or barnweddingvt.comally thought to be a skill only possessed by humans, some tool use requires a sophisticated level of barnweddingvt.com is considerable discussion about the definition of what constitutes a tool and therefore.

In fact, the use of animal ‘models’ has never been validated, and the claim that animals are necessary for biomedical research, is unsupported by scientific literature. There is, rather, growing awareness of the scientific limitations of animal research and its inability to make reliable predictions about human health.
