Explanation:

During body activities (such as walking, running, eating) the muscles of the body are contracting and relaxing, and utilizing energy compounds like glucose to produce ATP to drive these activities.

Many organisms can reproduce asexually through mitosis, while other organisms reproduce sexually, and their cells carry out meio
Darina [25.2K]

Answer:

C

Explanation:

Mitosis is a growth division unlike meiosis which an organism undergoes to produce gametes or sex cells during sexual reproduction.

Mitosis is a kind of cell division that results in two daughter cells, identical in genetic composition. An organism can undergo mitosis in asexual reproduction. For each mitotic division, two daughter cells emerge (duplication division), which will propagate the number of the species.

In a case of heavy predation, the prey organism will depend on diverse number to keep its species from getting extinct. Hence, undergoing mitosis to duplicate itself asexually will be most beneficial in this scenario as a large number will increase the chance that some of them will not be a victim of predation.

Which of the following is a reason why teeth are important to help identify
Lyrx [107]

Answer:

O4) All of the answer choices are correct.

Explanation:

Everyone that has teeth can be identified if they have a dental record. A forensic dentist can see what diet the person had, did they smoke, the age, the sex of the person and they are a source of DNA. We can examine the bite mark of the person in question and find out who they are. So teeth are very useful even when everything else on the remains is very badly damaged.

Another application of the Polymerase Chain Reaction (PCR) is to screen samples for the presence of viruses. For example, rememb
yuradex [85]

Answer:

For the 1st part, the correct answer is option C.  

In a polymerase chain reaction, the amplification of DNA template takes place not RNA. So, prior to going into the process, there is a need to initially convert RNA into DNA with the help of an enzyme reverse transcriptase.  

For the 2nd part, the correct answer is option D.  

The suitable temperature for human DNA polymerase is 37 degrees Celsius, and it gets denatured at greater temperatures. As PCR runs at exceedingly high temperature like 95 degrees Celsius, only Taq DNA polymerase can withstand the temperature. Thus, normal DNA polymerase cannot be utilized in the PCR reactions.
