It depends on what kind of experiments you're talking about.
Animal behavior experiments are generally done in order to understand why they behave the way they do, and by extension to help us understand why humans behave the way they do.
Drug trials are done on animals first in order to see if the treatment is a) effective and b) safe. Each species has its own metabolic quirks, so a treatment that is safe and effective in animals MAY not be so in humans, but it's a way to identify treatments that are at least POTENTIALLY safe and effective for humans.
Finally, some testing is done for teaching/training purposes. A school may have students experiment on, say, rats even though the expected results are known, in order to train the students how to perform experiments in which the results are NOT known.
Plus rats, mice, dogs,primates and cats all get used for expiriments. You may think-ew mice, rats, who cares about them? BUT THEY HAVE A LIFE TO YOU KNOW AND THEY WANT TO LIVE IT!
Because some animals, such as dogs and cats, are family pets and just like one of the family. They definitely have some of the same emotions as humans, such as faithfulness/love for their masters, fear, desire to be a real part of and a family member. If the family is inside the house, that's where the pet wants to be; if outside, that's also where the dogs wants to be, or inside the family car for a drive (cats prefer to stay at home and don't have the closeness to people that dogs have). Cats seem to like their "place" more than the "people."
Because many animals have some of the same brain capabilities as humans, but they are apparently disposable, so you can kill 50 monkeys so a human can figure out why their kid hates them...
Control groups are used in experiments for comparison purposes.
Conceptual variables are variables that are used as the basis of a hypothesis in experiments. Conceptual variables are abstract, as opposed to the concretely defined variables used in the experiment.
field experiments, lab experiments, observational studies, questionnaires; social psychology can improve the quality of our social interactions and explain why do some effects take place--once we understand it we try and change or influence it

For brain or drugs experiments, rats are frequently used but dogs and monkey are also used a lot.

Many animals are used for animal experiments. These animals are mice, rats, monkey's, dogs, bunnies, birds, fish, frogs, cats, and even hamsters. These animals do not deserve to be treated like this. help stop this by going to google.com and searching up animal experimenting protest. you can donate money to the company, and even volunteer to help.
According to the Vivisection Information Network, "Estimates exist that 100 million animals are used wordwide, which is about 274,000 per day, or three every second. However, this estimate is for vertebrates only."According to People for the Ethical Treatment of Animals, in the United States in 2010, 1.28 million animals were used in experiments (excluding rats, mice, birds, reptiles, amphibians, and agricultural animals used in agricultural experiments), plus an estimated 100 million mice and rats. In Canada in 2009, 3.38 million animals were used in experiments. Of those, 145,632 animals were subjected to “severe pain near, at, or above the pain tolerance threshold of unanesthetized conscious animals.†In the United Kingdom in 2012, there were 4.11 million experiments on animals, and 2.95 million of those were without anesthesia.
Yes
It is unreligeous to experiment on animals.

Yes, they are used in experiments in some places :)
because it might hurt their feelign being used like that.
In Cows
Gregor Mendel used pea plants for his hereditary experiments
