Basically certain traits are going to give a better outcome for the animal the white rabbits living on white snow are going to be able to survive better than the brown rabbit and the population of brown rabbits will be reflected through the graph
After the macrophage fails the Helper T Cell stimulates the B cells if pathogen is extracellular and Cytotoxic T Cells if the pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.
<span>The discoverers of DNA were not James
D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”</span>
Answer:
Through natural selection, those organisms which have better adaptations to survive in an environment are able to live and pass on their alleles to their offsprings. Hence, any trait which is beneficial to an organism will be favoured by natural selection.
As tissue pockets is a trait which is required by the shrimps, hence with the passage of time shrimp population having tissue pockets will increase and will be favoured by nature.
