Evolution is caused by genetic mutations that become favorable for survival.
For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.
Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.
Answer:
The movement pushes food and liquid through your GI tract and mixes the contents within each organ. The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food to move. The digestive process starts when you put food in your mouth.
The above statement is true. The depressant effects of alcohol does not interfere with the conduction of the electrical impulse. Alcohol is a depressant in the sense that it slows the cardiovascular system. It can also be considered a depressant since it relaxes an individual and reduces the intensity of stimuli. However, at low quantities it acts as a stimulant and may also stimulate certain activities such as talking and make someone happy as opposed to being depressed.
Families typically contain may species, so the percentages of families that became extinct is lower than the percentage of species that became extinct.
