Answer: High calories diet

Explanation:

Independent variable can be defined as the factors which the experimenter can control and the the dependent variable depends on the independent variable.

Here, the experiment is to test the effect of high calorie diet on the animal's weight.

The experiment is to test whether the animals gain weight if supplied with high calorie diet.

So, the independent variable in the experiment is high calorie diet and dependent variable is weight of animal.

Evolution can be guided by random processes. What is the effect called when some genotypes are lost in a small population over t
soldi70 [24.7K]

Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

The inability of the body to adequately circulate blood and oxygen to the body's cells is known as
Arada [10]
Circulation of the blood is crucial in the body since it helps in supply of nutrients and oxygen to all parts of the body. It is these nutrients and oxygen that are key in the activities of a cell or a tissue without which the cells wont efficiently carry out their functions.The inability of the body to supply blood and oxygen to the body cells as required is known as hyperfusion. Hyperfusion is caused by inadequate perfusion of the body tissues and thus resulting to inefficient supply of nutrients and oxygen gas to the body cells and tissues.

NikAS [45]

A simple or closed fracture does not break the skin. This is further explained below.

<h3>What is a closed fracture?</h3>

Generally, a closed fracture is simply defined as a situation whereby the skin hasn't been damaged, even if the bone is cracked.

In conclusion, If the fracture is simple or closed, no blood will be seen on the skin. More detail about this is provided below.
