Explanation:
It is called Adenosine Tri-Phosphate
Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)

Hence, The pH of a solution containing 0.1 mM H+ is 4
AnswerThese are the enterocoelomates.Starfish, sea urchins are examples.Generally animals of the phyla annelida, molluscs and anthropoda belong to this group.
They are animals formed by enterocoely; in which the mesoderm arises from the wall of the embryonic gut archentron. The latter is an hollow outgrowth which forms the coelom.It is the type of coelom found in deuterostome animals.
Explanation:
<span>B- tree > insect > frog> snake> hawk
The food chains are represented by organisms interconnected by red arrows that point in the direction of the one that's eating. So, the relation that is explicit by the arrow is that the organism from where the arrow departs is eaten by the organism where the arrow is pointing towards to. So, the food chain that can be observed accurately in the food web is: the tree is eaten by the insect, the insect is eaten by the frog, the frog is eaten by the snake, and the snake is eaten by the hawk.
