Beavers are descendants of land-dwelling rodents similar to rats. The beavers however have adapted their body shape to live in water bodies like ponds and lakes. This can be hypothesised by saying that the early rodents or the ancestors of beavers were forced to find food in the waters. They lacked the flat tail and the webbed feet. With time the need to increase their ability to catch fishes and floating insects, the rodents with flatter tail and a bigger flat webbed feet gradually evolved. The rodents with flatter tails and webbed feet became adjusted to the life on water and became the modern day beavers.
Overproduction is a natural phenomenon in which the number of produced offspring is higher than the number of individuals the ecosystem can sustain. Thus, competition for limited resources occurs.
Because of the genetic variation, the organisms within a population have different chances to reproduce. Most often, some organisms have a lower reproductive success than others do.
The number of individuals with a high reproductive success is rather low as few males are very successful at passing on their genetic material.
The number of organisms with no reproductive success is also very low, as these "ill adapted" individuals will disappear from the population extremely quickly.
Genetic variation is the amount of differences between individuals. Thus, no organism taken by itself has any genetic variation.
A white blood cell engulfing a bacterium is an example of blood functioning in protection.
<h3>What is a white blood cell?</h3>
White blood cells or better called leukocytes are blood cells produced in the bone marrow that belong to the immune system which are responsible for the <u>protection </u><u>and</u> <u>combat of infections and diseases</u>.
There are different types of white blood cells, among these are: <em>neutrophils, eosinophils, basophils, monocytes and lymphocytes</em>.
Usually the blood count of these leukocytes is used to detect situations such as infections, allergies, inflammation or leukemia.
Therefore, we can confirm that a white blood cell engulfing a bacterium is an example of blood functioning in protection.
