Blue Carb which scientifically is known as “<span>Callinectes sapidus” is a type of vertebrates. </span>A possible reason for the fluctuation in their population can
be the eutrophic dead zones in the Chesapeake Bay which naturally cases low
levels of oxygen dissolving into the Bay leading to fluctuation of Blue crab
population.
<span>Another reason also can be the shorter
life span of blue crab, its average life span recorded is one to three years
which is very short in comparison to striped bass, although some blue crabs are
caught after being tagged at the age of 6 to 8 years as well.</span>
Answer:
The discovery of Chromosomes
Explanation:
a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.
It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.
b) Graph is already uploaded in the below attached document.
c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.
d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number
Explanation:
Frequency of animals in population 1 having both alleles 1 and 3
frequency of allele 1 =0.60
frequency of allele 3= 0.25
Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100
= 0.60+0.25 X 100= 85%
Dalton's atomic theory said, apart from other things, said that an atom was the smallest things and that all matter was composed of atoms.
But J. J. Thomson discovered the electrons, particles smaller than atoms, and after that, changes to Dalton's theory were made.
