Highlands because the climate changes the higher you go up in the hemisphere
The correct answer is the fundus.
The stomach is divided into parts of which the fundus is the second;
it stores all the undigested food and the gases that are released from the
chemical breakdown of the food we eat.
The correct answer is D: stable and not growing or shrinking. I hope this helped:)
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: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
