The first one is web and the last one is chain. I'm not sure though.
Explanation:
The oxygen-rich surface water blends with the deeper, depleted water. The dissolved oxygen concentration in the mix can be too low to support life in the pond. Both fish and plankton can die from low dissolved oxygen following a turnover. Thus, turnover can happen if a cold rain and wind cools the surface water.
Answer:
it causes the rapid increase in PH which may harmful for the for fishes and other aquatic lives.
Explanation:
There are a lot of materials which are used to neutralize the acidity of soil.some examples of such materials are slacked lime, quick lime, and liquid lime etc. Lime increases the PH and the concentration of calcium which helps in removal of phosphate from water. Raising PH also cause to remove the carbon dioxide from the water. But keep in mind that rapid increase in PH is harmful for the fishes.calcium oxide also causes the rapid increase in Ph therefore, it is not advisable to use in fishpond.
The different chromosomal combinations would be calculated using the formula;
2^n; where n is the number of different chromosomes. \
Using this formula ; when the diploid number is 14 (for 7 pairs ) will be given by; 2^7 = 128 different combinations.
It means that a barley plant which has seven pairs of chromosomes will have 128 different combinations.
Nucleotides can be radiolabeled before they are incorporated into newly forming DNA and, therefore, can be assayed to track their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides to study the incorporation of labeled nucleotides into a culture of lymphocytes. They found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they might conclude from this observation is that the Infection causes lymphocytes to divide more rapidly
- Lymphocytes is a type of immune cell produced in the bone marrow and present in the blood and lymphatic tissue. B lymphocytes and T lymphocytes are the two main types of lymphocytes. T lymphocytes help eliminate tumour cells and govern immune responses, whereas B lymphocytes produce antibodies. A lymphocyte is a white blood cell type.
