i think the answer is A if its wrong im sorry
Explanation:
Answer:
CLAIM: IF THE FUSED B CANCER CELLS ARE GROWN IN A MEDIUM THAT DOES NOT CONTAIN NITROGEN SOURCE, THE CELLS WILL STOP SYNTHESIZING PROTEINS AND THEIR LIFE SPAN WILL BE GREATLY REDUCED
Explanation:
The growth medium that was used to reproduce the fused cancer B cells contains nitrogenous compounds that serves as source of nitrogen for the production of nitrogenous bases of DNA, If the nitrogen source is removed, the DNA in the nucleus of the white blood cell will lack adenine and guanine, which are necessary for the synthesis of DNA molecules.
2. Nitrogen is an integral part of DNA and protein. Nitrogen is needed to produce nitrogenous bases that are found in DNA. The DNA molecule is the one that initiate and direct the synthesis of protein in living cells.
In the fused B cancer cells, DNA must be produced, so that the dividing cancerous cells can continue their uncontrolled division, this will keep the cells alive. Nitrogen is also needed for the continuous synthesis of the special protein that the fused B cell is producing.
Thus, if nitrogen source is removed from the growth medium used for the cultivation of fused B cells, then the cells will stop synthesizing protein, their life span will be greatly reduced and they will eventually die out.
Answer:
<u>C</u>
Explanation:
Habitat loss matters as this greatly reduces the organisms that live there and causes a decline in species diversity.
