I wanna say it's sand stone but I'm not sure what you are learning about
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).
Answer:b. an mRNA transcript to which multiple ribosomes are attached
Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.
Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.
Answer:
C. natural selection
Explanation:
Natural selection is when the organisms that have the better adaptation so they survive. In this case, the green was the better adaptation so they lived.
The main function of mitosis is to allow for growth and development and to replace dead and or decayed tissue.
