You forgot to include options.
The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.
Answer: YES, SUPPORTED
Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.
These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.
In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).

<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>
Explanation:
Let us understand the term DDT
DDT : Dichlorodiphenyltrichloroethane
- This is a crystalline chemical compound
- Basically used for protecting insects eating crops
- It is colorless, odorless, tasteless
- Initially used as pesticides
It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.
It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.
It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures
It contained toxins: It contains moderate toxins.
Answer:
14amu
Explanation:
Given subatomic particles:
Number of protons = 7
Number of Neutrons = 7
Number of electrons = 7
Unknown:
Atomic mass unit; amu of nitrogen
Solution:
The atomic mass unit of a substance is the number of protons and neutrons in such an atom;
Atomic mass unit = number of protons + number of neutrons
This is because the mass of an atom is concentrated in the nucleus;
For the given specie;
Atomic mass unit = 7 + 7 = 14amu
