What is the impact of the depletion of fishing stocks?
ziro4ka [17]
It is the same as creating more pests or setting up dominant species which upset the ecological food pyramid leading to decimation of trophic levels or predators and energy cycling. Fishes feed on microscopic algae and animals the primary base of the food chain in water, if they are not checked they will choke the rivers and oceans causing toxic waters. Fish feed to contain them, in the process they grow and increase in numbers but their population is checked by bigger fishes and so on till it reaches a top predator which is usually a large animal.

A species of fly has two alleles for the length of their legs. The allele for long
postnew [5]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

Explanation:

According the question

 q represent the short legs and 33 of 100 organism have short legs.

    As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                   =0.33

Therefore q=0.33

     we all know that

                   (p+q)2=1

              ∴  p+q= 1

              ∴  p=1-q

                   p= 1-0.33

                    p=0.67

The frequency of p is 0.67
