Answer:
The Loop of Henle serves to create a concentration gradient throughout the nephron which helps increase the reabsorption of water and certain ions. In the thin descending limb, water is very permeable and is reabsorbed due to the existing concentration gradient in the medulla.
Answer:
Metaphase
Explanation:
The metaphase stage of the cell cycle precedes the anaphase and the telophase stages. During this stage, the metaphase plate is formed and chromosomes align along this plate which also represents the equator of the cell.
After lining up, mitotic spindles attach to each chromosome at the centromere. Shortening of the spindles results in separation of sister chromatids of the same chromosome and their eventual migration to the opposite poles of the cell.
<em>Hence, if the mitotic spindle refuses to attach to chromosomes, cells would most likely be arrested in the metaphase stage and will never be able to proceed beyond it.</em>
Answer:
#1 is correct
Explanation:
kelp also needs nutrients that are only available in deep water or near shore but not on the surface of the open ocean.
Answer:
B. Protect us from harmful ultraviolet Radiation.
Explanation:
I did this in 6th grade. The ozone layer contains a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.
So mitosis will start with interphase which will be the longest step. Inside of interphase there will be and S phase where the DNA will be copied. Then the PMAT phases then these phases are where the cell is actually dividing and it ends with cytokinesis with the cell splitting one membrane into two different membranes.
