Hey mate, here is your answer
Three ways by which nitrates are transferred from the land to water are :-
Δ The roots of the legumes undergoes symbiotic association for the intake of nitrogen. They form nitrates. So these plants help in transferring solid nitrate to water nitrate
Δ Animal wastes has nitrates. So these nitrates along with rain water can go to rivers
Δ The lightening strikes contain nitrogen which is converted by plants during nitrogen cycle into nitrates which then eventually goes into water
EFFECT ON HUMAN HEALTH
The nitrates are good when eaten. They help in proper functioning of body parts. But its also harmful if its contain is too much. Nitrate and Methemoglobinemia. Methemoglobinemia, or blue-baby syndrome, is a condition caused by the inability of the blood to deliver enough oxygen to the body. It is the most well-known effect of exposure to elevated levels of nitrate in drinking water.
EFFECT ON ENVIRONMENT
Nitrate in water is too dangerous for animals in aquatic. They can die if they start consuming nitrates
Answer:
B -the absence of the inducer, but not in its presence
Explanation:
In positive repressible regulalor mechanisms transcription of the structural gene(s) occurs in the absence of the inducer because proteins are normally bound to the pertinent DNA segment. when an inhibitor is bound by the inducer, it is prevented from binding the DNA. which will the stops the activation and transcription of the structural genes.
Example of positive repressible regulator is Activator .
Regulating the rate of transcription is a mechanism of gene regulation leading to the productionn of more than one protein product from a single gene.

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.
Explanation:
Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)
Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>
After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
