Answer:It is this coupling of chemistry and movement that gives proteins the ... to place the protein in a particular location in the cell—an example is the SH2 ... At one level, the cell controls how many molecules of each enzyme it makes ... One of the best understood pump proteins is the calcium transport protein from muscle cells.
Explanation:
Hope this helps.
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.

Answer:
One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.
One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.
The correct answer is: d. it contains many light-sensing columns called ommatidia
Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.
The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
