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!

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimil
Arada [10]

Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes
