A decrease in the population of bears
Answer: Genetic Drift
Explanation:
It's all based on sampling errors.
Explanation:
Understanding through into genetic risk factors for various illnesses in the human population come from mouse research. Manipulation of the mouse genome is quite simple, for example, adding or deleting genes to better understand their function in the body.
The majority of mice and rats used throughout medical studies are inbred, which means they are genetically virtually similar, making the outcomes of medical trials more consistent.
Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
