Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.

The nitrogen base pairs in the DNA molecule are adenine and
Mila [183]

Answer:

Explanation:

The four nitrogenous bases are A, T, C, and G. They stand for adenine, thymine, cytosine, and guanine. The four different bases pair together in a way known as complementary pairing. Adenine always pairs with thymine, and cytosine always pairs with guanine.

If you could measure the resting metabolic rate of the following animals, which would most likely have the lowest mass-specific
yawa3891 [41]

The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.

The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.

Explanation:

The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.

Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.

However metabolic rates of ectotherm and endotherm cannot be compared.
