RUNOFF OF OIL FROM ROADS
Eutrophication is a phenomenon used to describe an INCREASE in the concentration of nutrients in a particular aquatic area (lake) leading to the proliferation of plant or algae growth. Proliferation is majorly caused by the RUNOFF of substances containing these nutrients into a water body.
According to this question, eutrophication can be caused by the following:
- Runoff of manure from farms: Manure contains nutrients that can cause an increase plant/algae growth.
- Runoff of fertilizers from neighborhood: Fertilizer contains certain elements such as nitrogen, phosphorus, potassium etc. that serves as source of nutrients for aquatic organisms.
- Excessive nutrients: Too much of nutrients lead to uncontrollable growth.
Among these options, runoff of oil from road is NOT a cause of eutrophication because OIL inhibits growth rather than induce it.

Answer:
When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.
Explanation:
If someone has blood type A, they must have atleast one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. while an individual with blood type B will have a genotype of either BB or BO. Individuals with type O blood will have a genotype OO. Both A and B alleles are dominant over O.
Therefore, the genotype of the man is AO, that of the mother is BO, while that of the child is OO.
In future from this marriage, the possible genotypes are;
AO, BO, AB, or OO
In the frequency of 1/4 each.
Germ cells because what goes through mitosis is somatic cells
