Answer:
Algae are phytoplankton capable of photosynthesis. How do ocean currents affect algae populations? A) Ocean currents deposit nutrients at the ocean floor, where the algae are present. B) Ocean currents push the algae to the ocean floor, where the nutrients are present. C) Ocean currents move the cold, nutrient-rich water to the surface to provide renewed food source for algae. D) Ocean current move algae from the poles toward the equator, where the amount of sunlight received is more.
The answer is c
Explanation:
The question is asking to state the substance that come from the outside in the process of photosynthesis, base on my research and further investigation, I would say that its the heat or light energy. I hope you are satisfied with my answer and feel free to ask for more
The sulphur would lable the capsule and the phosphorous the nucleic acid.
<h3><u>Explanation</u>:</h3>
Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.
This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
The correct option is this: NATURAL SELECTION FAVOR G6PD DEFICIENCY AS COMPARED TO MALARIA.
As we are told in the passage given above, G6DP enzyme helps the red blood cells to function very well. So those people who lack this enzyme have red blood cells that are not functioning very well and this usually result in heamolytic aneaemia. Remember that the parasite that cause malaria normally need red blood cells to survive, thus, for people who lack G6DP malaria can not survive in their blood. Since lack of G6DP enzyme mostly occur in people of African origin where mosquitoes abound, researchers believe that the lack of G6DP enzyme in these people red blood cells is a natural selection method by which the body is preventing itself from been attacked by mosquitoes.
it's b. anaphase and spindle fibres pulls chromosomes towards the centrioles in this phase.
