Explanation:

A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.

Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

The ocean is called the carbon sink because there is mass amounts of carbon all the way at the bottom. How did the carbon get th
Solnce55 [7]

There is absorption of carbon dioxide by the oceans through physicochemical (air-sea surface exchange) and biological processes. During physicochemical process, molecules of CO2 get into the ocean by diffusing into the sea surface waters and dissolving. Various factors such as wind, sea surface mixing, concentrations of CO2, and the temperature of the water influences the amount of CO2 that diffuses and dissolves in the ocean surface water. Also, during biological processes, dead cells, shells and other parts of dead organisms get decayed and releases carbon dioxide at the bottom of the water.
