Answer:
The correct answer is C. catalyze the removal of phosphate residues from proteins
Explanation:
The function of protein kinase is to transfer a phosphate group to the amino-acid present in a protein and the function of protein phosphatase is to catalyze the removal of the attached phosphate group from amino acid of a protein.
Protein dephosphorylation is an important event in the post-translational modification process. Through dephosphorylation, phosphatases change the protein behavior by activating and deactivating the proteins.
Phosphorylation and dephosphorylation of proteins are important in managing several crucial processes in the cell like cell signaling, apoptosis, cell cycle, etc. So the right answer is C.

<u>Answer:</u>
<em>Climate change positively affects organisms by </em><em><u>providing them new habitat.
</u></em>
<u>Explanation:</u>
Climate change induces <em>changes in various parameters of an ecosystem </em>like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in. 
But this <em>new conditions</em> may be favourable for some other kind of organisms to thrive and flourish.
<em>For example, </em>when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of <em>native cold water organisms of the lake. </em>
Thus climate change doesn’t bring any benefits to living world without harming one or the other <em>group of organisms.
