The answer you chose is right
Answer:
The edges or boundaries between the ecosystems and within it are the illustrating characteristics of landscapes. In a landscape, the biodiversity is affected by the composition of the landscape itself. When an area possesses boundaries or edges, which minimize the area of the habitat, it also starts to minimize the number of species, which can associate with the communities.
The multiplication of edge species can exhibit both negative and positive influences on the biodiversity of a community. On the other hand, corridors refer to the region associated with the populations of wildlife distinguished by human activities like road construction. The prime objective of designing habitat corridors is to enhance biodiversity. The corridors that have been protracted to other habitat patches can reinstate a certain degree of space and at the same time reestablish certain chances for genetic diversity.
The sets of alleles for each parent are Dm for the mother and DM, Dm, dM, and dm for the father. This information is fundamental for estimating genotype and allele frequencies in offspring.
<h3>What are alleles?</h3>
Alleles are gene variants for a given gene <em>locus</em>, diploid organisms inherit two alleles for each locus (one from each parent).
Gametes are germinal (haploid) cells that carry specific allele combinations.
The analysis of gamete combinations is fundamental to estimate genotypes and allele frequencies.

Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
