How are endocrine system and nervous system similar?
Fofino [41]
Hello,

The answer is "one is what controls functions in the body the other one is what helps the body feel things in order to have the other system control the pain and lets the brain know so it can react and have the cells repair the damage done to the body".

Reason:

Endocrine Systems: It provides functions for the body.

Nervous System: It lets the body feel and reacted to something that can damage the body.  

So basically a person touch's a hot stove which causes the nervous system to send a message to the brain telling it that it hurts which is where the endocrine system comes in and provides the function to allow the hand to move quickly away from the heat in order to protect the body.

If you need anymore help feel free to ask me!

Hope this helps!

The rate at which respiration is occurring in a mammal can be indicated by the rate of
Vitek1552 [10]

Answer:

All life respires, or breathes. Respiration in mammals is similar to respiration in other air-breathing animals. Respiration extracts oxygen from the air, which is then used by cells. Respiration also carries waste carbon dioxide away from the cells. Although respiration depends on other systems, like the circulatory system, to take oxygen and carbon dioxide to and from cells, the respiratory system has the primary responsibility of bringing oxygen in to a mammal's body and sending carbon dioxide into the atmosphere.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.
