Answer: Positive: Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
Negative: Added to this are impacts such as increased erosion due to coastal development, increased pollution, and increased boat traffic - all of which lead to further habitat loss and put increased pressure on marine species. ... Other coastal developments can also harm sensitive marine habitats and species.
Explanation:
Answer:
<em>If all variation among individuals in a population is due to differing genotypes alone, heritability is 100% and the slope of the line used to measure it is 1.</em>
Explanation:
If the genes play no role in the variation among organisms of a species, then the heritability will be zero percent. Hence, if all the variations among individuals of a population occur due to the differences in the genotype, hence the heritability will be 100%. This is because genes are the hereditary molecules and the genotype of an organism comprises of the different genes present in an organism.
Answer:
Frequency of recessive allele 
Explanation:
Given -
Total Population size = 919
Number of individual with recessive genotype = 341
Frequency of recessive genotype
Frequency of recessive allele 
Hence, option C is correct
