Feedback mechanisms how do organisms regulate complex systems through chemical interactions

1 answer:

8 0

Organisms regulate complex systems through chemical interactions through feedback mechanisms. The feedback mechanism can respond to perturbation either as positive feedback (the same direction) or a negative feedback (opposite direction). The contractions in childbirth is an example of positive feedback. The hormone oxytocin is released in the body when contraction begins to further aid the contractions. An example of negative feedback is the regulation of blood glucose level. The continuous rise of blood glucose level may lead to diabetes.

Why is osmosis important to the survival of a cell

stiv31 [10]

The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.

You are treating a 13-year-old female who has a broken stick impaled in her forearm. there is some minor bleeding from the site.

yan [13]

Answer:

apply direct pressure to the injury site while manually stabilizing the stick in her arm

Explanation:

Spinal immobilization can generally be explained as the use of adjuncts such as cervical collar, that are being applied to minimize movement of the spinal column.

In this case, since the area where the girl is injured is the forearm, it has no direct connection with the spinal column, this means that, the cervical spinal immobilization is unnecessary.

Therefore, there should be direct application of pressure to the injury site while manually stabilizing the stick in her arm.

N the cross shown here, involving two linked genes, ebony (e) and claret (ca) in drosophila, where crossing over does not occur

jonny [76]

I found the full exercise on the internet and it ends like this:
"These genes are 30 cM apart on the third chromosome. Explain how this ratio arose." Attached is an image of the cross mentioned above.
Crossing over in the female contributed to the possible existing allele combination |e-ca| that did not exist in the parents genotypes. With this new allele combination, the new possibilities are |♀e-ca/♂e-ca+|, |♀e-ca/♂e+-ca|, |♀e+-ca+/♂e-ca+|, and |♀e+-ca+/♂e+-ca|, leading to the respectively phenotypes ebony, claret, wild, wild. These results correspond to the obtained phenotype ratio.
