The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
Answer:
Due to genetic defects, a family history of hormone imbalances, or certain diseases.
Explanation:
According to the data, the blood is deficient in hormones which is due to a number of factors such as genetic defects, a family history of hormone imbalances, or certain diseases etc. The normal person has 10-20 units of hormones per ml of blood in their body, if the body has low in hormones the body does not perform its function properly that leads to certain diseases such as obesity, osteoporosis, and cardiovascular disease so we can say that genetic defects, hormone imbalances, or certain diseases are the causes of low in hormones.
Algae living on a sloth is considered an example of mutualism because both of them benefit from each other.
Mutualism is one of the symbiotic relationships in which both the two species living together benefit in one way or another. A considerable example of such a relationship is between algae and a sloth.
The algae provide camouflage to the sloth and protect it from predators while the sloth provides shelter to the algae for its growth. The sloth also gets nutrition from algae which perform photosynthesis and synthesize food.
Another mutual relationship is observed between the aphids and ants. Aphids produce honeydew as a waste product of their diet which is consumed by ants. While ants protect the aphids from predators and parasites.
