Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation.
This interaction is an example of environmental factors affecting <u><em>genetic expression</em></u>. In these situations, the environment causes specific segments of DNA to be expressed, meaning they are transcribed to mRNA and subsequently used to form proteins.
Meanwhile, other parts of the genome remain or are forced to be silent. This can be a result of mutations or simple biochemical reactions between the environment and the genome.

Answer:
4
Explanation:
The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.
The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.
* Blood cells isn't an organ system which makes 1 incorrect.
* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.
*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.
Snorks only have one chromosome with 6 genes on it. Your job is to analyze the DNA of a Snork and determine what traits the organism has. Suppose you analyze a Snork's chromosome and you determine that it has the DNA sequence below. ... Your job is to determine the sequence of amino acids that this DNA codes for._______ hopefully this answers works for you but if not just message me for the other answer bc there is two. Good luck
