PLEASE HELP ASAP :( Having a tough time, and can't solve this for the life of me. Examine the image of molecules involved in the signaling pathway:

The signaling pathway shows how different molecules act as second messengers to bring about a cellular response. Based on this model, which of the following causes a decrease in cellular response?

An increase in phospholipase C activity
An influx of Ca2+ into the cytosol
Closing of IP3-gated calcium channels
Formation of IP3 and DAG from PIP2

the answer is a) a shiprock was formed by igneous process

i think it is dna, i'm not totally sure but i think it might be.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

genetic variation will increase because of a new habitat and food source.
