Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
Answer:
O.
Explanation:
There are different types of soils and it is made up of different layers or horizon such as A, B, C, O, R and E. Together all the horizons forming soil profile. Each horizon containing different soil types.
O horizon: Known as top layer of the soil which contains layer of organic matter which is about two inches thick, and made up of humus such as decomposing leaves, dark-colored, carbon rich matter, twigs and microbial biomass which is mixed with small grained minerals for the formation of aggregate structures.
Answer: hello some details relating to your question is missing below is the missing detail
DNA Sequence= 3’ - TACTAGTTGTGCATT - 5’
Complementary Sequence=5`-ATGATCAACACGTAA-3`
Answer : MINT
Explanation:
The protein ( sequence of amino acids ) that resulted from your Translation is MINT
The m-RNA Produced form the information above is:
5`-AUGAUCAACACGUAA-3`
While the Protein Sequence is Met-Ile-Asn-Thr which can be written as MINT
Answer:
Scientists use a system like this to group living things. the grouping are based on common traits. this system helps scientists to study the million of organisms of new organisms are discovred each year
This is your answer...
plz... thanks me
<span>The most expectant evolutionary feature would be longer necks. This will enable the tortoises to reach the higher grass. This <span>would occur through natural selection that would favor the extreme traits (alleles of long neck) of long necks in the population.</span></span>
