Are you talking about the esophagus?
Answer/Explanation:
First, initiator protein unwinds a short stretch of the DNA double helix. <u>The length of the DNA double helix about to be copied must be unwound. </u> In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases. Once the DNA strands have been unwound, they must be held apart to expose the bases so that new nucleotide partners can hydrogen-bond to them. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
The answer is C, or Adaptations increase the chances that an individual will reproduce and pass its genes onto the next generation. Such traits then become more common within a population.
Answer:
-Plant cell has a cell wall and animal cell does not.
-Large vacuole present in plant cell and little or no vacuoles present in animal cell.
<h3><u>Answer</u>;</h3>
A. Pressure causes water and dissolved substances to filter through capillary walls of the glomerulus.
<h3><u>Explanation;</u></h3>
- <em><u>During filtration the flow of blood in the glomerulus creates hydrostatic pressure in the glomerulus which forces molecules through the glomerular filtration membrane. </u></em>
- Normal filtrate contains of water, glucose, amino acids, urea, creatinine, and solutes such as sodium chloride, calcium, potassium and bicarbonate ions.
