1.What is a codon? What does it tell the ribosome?
Sophie [7]

Answer:

1. A codon is a triplet of nucleotides that codes for an amino acid. This amino acid is transported by the tRNA which possesses a complementary anticodon and it gets added to the nascent protein.

2. Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.

3. the onset of protein production is signaled by the AUG codon which encodes methionine. the stop to the synthesis is given instead by the stop codons (UAA, UAG, UGA)

4. Met-Val-Thr-Ser-Arg-Leu-Stop

Explain why primary ecological succession usually takes hundreds or thousands of years.
krok68 [10]
Primary succession is much slower than secondary succession because it begins where there is no soil. It can take several hundred to several thousand years to produce fertile soil naturally. The first pioneer species to colonize the bare rock will probably be bacteria and lichens, which can live without the soil.

Kira got out of breath while performing, and began breathing slower and deeper after the performance. Which of the following bes
kotegsom [21]

Answer:

(A)

Explanation:

In question number one, it is important to understand that during exercise, the oxygen hemoglobin dissociation curve shifts to the right. This is also confirmed by the fact that the patient, Kira is also breathing slowly. CO2 builds up in the both as patients begin to hypo ventilating. Most likely this patient in in a state of respiratory acidosis. But, it is important to understand that when the curve shifts to the right in this situation, you have decrease affinity of Hb for O2, meaning that the O2 does not want to bind to the hemoglobin. It instead is gonna wanna go straight to the tissues so that the tissues can get oxygen during high exercise states like this one. If the tissues don't get oxygen then you would have elevated lactic acid production in the tissue and the body would go into a sever state of lactic acidosis. So during excercise and increased CO2 content in the blood due to hypoventilation post excercise, our body's natural mechanism is to dump all the oxygen we get directly to our tissues and bypass the hemoglobin that is circulating in our vessels. So that being said you should be able to answer the question above. The hemoglobin would be less saturated with o2 in this case.

Hope this helped !

Why is it important that antibodies have a symmetrical quaternary structure? to enable binding to many different antigens to cre
Morgarella [4.7K]

<span>It is important that antibodies have a symmetrical quaternary structure to create two identical binding sites for antigens. An antibody is a relatively large protein having a Y-shape. Plasma cells produce antibodies which are then used by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody is able to recognize the antigen of the pathogen. It binds with it either to neutralize it directly or “tag” the microbe for future attack by other parts of the immune system. </span>
