<span><span>B. a negative feedback loop because the blood glucose level was returned to the set point, not amplified
</span>The glands which get involved are the pancreas and adrenal glands.</span><span> During increase in blood sugar, the pancreas secretes insulin, a hormone produced by the beta cells of the pancreas. Insulin causes red blood cells, muscle cells and fat cell to absorb sugar from the blood.</span><span>During decrease of blood sugar, the pancreas secretes glucagon, a hormone produced by the alpha cells of the pancreas. Glucagon causes the liver to release the glucose stored in its cells.</span><span>The Adrenal gland secretes cortisol during times of low blood sugar levels. Cortisol promotes the use of fatty acids to provide energy for working muscles, rather than using glucose.</span>
Answer in the gene for that characteristic cause these different forms. ... These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways
When two protein chains combine to form an active protein, the structural level is quaternary.
<h3>What is a quaternary structure?</h3>
The quaternary and tertiary structure of a protein is the tridimensional shape of the protein, which involves protein domains.
The quaternary protein structure refers to the different arrangements generated by different protein subunits.
The primary structure of a protein involves its amino acid sequence, whereas the second structure involves protein chains.
