Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.

Answer:
<u><em>This is because the enzymes might work best at higher temperature than 37 degrees Celsius. Increase in temperature will increase the catalysis of the reaction.</em></u>
Explanation:
<em>When the temperature is increased, the molecules possess greater kinetic energy. This will allow more substrate and enzymes to collide. As a result, there will be more enzymes taking place in the reaction which will cause the rate of the reaction to increase.</em>
<em></em>
However, if the temperature goes too high, then the shape of the active site of the enzymes will get changed. The enzyme will deactivate and the reaction will stop.
Answer:
A) Food enters the mouth
B) Esophagus
C) Stomach
D)Cecum
E) Feces is expelled
Explanation:
The food is ingested through the mouth and and then it is transported through the esophagus to the stomach from where it reaches the small and large intestine and then it is finally expelled as undigested or waste foo product.
Based on the above brief explanation, the flow chart depicting food movement are as follows -
a) Food enters the mouth
b) Esophagus - known as the food pipe
c) Stomach
d)Cecum - it is a small pouch connected to small and large intestine.
e) Feces is expelled through rectum
Answer:
Declining populations of phytoplankton, the basis of the marine food chain, will alter the seawater hues, potentially decimating fisheries. The world's oceans are warming and growing more acidic as a result of climate change, and a provocative new study suggests they'll be changing color too.

Hope this is good :)
