The investigators could distinguish human hair from animal hair by the patter of pigmentation and by the medullary index.
The pigmentation in human hairs is denser toward the cuticle, whereas in animal hair is denser toward the medulla. Human hairs are usually one colour throughout the whole length, while animal hairs may change colour suddenly.
The medulla in humans is thinner than in animals: the medullary index for human hairs is 0.33 or less; the medullary index for animal hairs is 0.5 or more.
This is known as parasitism.
In biology, parasitism is a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.
A proposed explanation for a wide range of observations and experimental results that is supported by a wide range of evidence. ... Most factors are held constant in a scientific experiment because you can only change one factor in an experiment so if you notice something, you'll know what caused it.
Answer:
True
Explanation:
Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.
