Answer:
During presentation of APC-bound antigen, macrophages and dendritic cells secrete the cytokine, interleukin-1, that activates T helper cells
Explanation:
Macrophages interact with T cells in order to generate T cell activation in target organs, and are themselves activated by inflammatory messenger molecules (cytokines) produced by the T cells.
Macrophages produce toxic chemicals, such as nitric oxide, that can kill surrounding cells.

The factor that CITES fail to consider when determining which species to cover is the Ecosystem sustainability.
A sustainable ecosystem is a biological environment with a series of habitats that is able to thrive and also support itself without outside influence. it is the capacity of the biosphere to meet the needs of the present generation, without hindering future generations from being able to meet their needs.
Answer:
The correct answer is 3' UCA 5'
Explanation:
The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.
Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.
Therefore the correct answer is 3' UCA 5'.
Answer: B. reforestation
Reforestation is the process of growing plants and trees in an area on large scale in order to create land a forest reserve which can allow the growth and abundance of floral and faunal species in future. Reforestation is the biodiversity restoration method that the biologist should use to meet their goals like : recreation of habitats for wildlife in a particular area, help against climate change as plants are the fixers of atmospheric carbon utilize this for photosynthesis and prevents the raising of atmospheric temperature.
The blood collection centers eventually refuse to take her blood because the frequency with which she gave blood had left her anemic.
Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin.
<span>Therefore her heart must pump more blood to compensate for the lack of oxygen in the blood. The consequences are huge, leading to an enlarged heart or heart failure.</span>
