Explain its normal role and why scientists would regard it as the "guardian of the genome."

1 answer:

5 0

The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.

The United States ranks 50th in the world for maternal mortality and 41st among industrialized nations for infant mortality rate

siniylev [52]

Answer:

Answer is B. Ensuring early and adequate prenatal care.

Explanation:

Prenatal care can be described as the care, such as information and medical care , given to pregnant women during pregnancy , before delivery.

This is very important , because it prevents complications during pregnancy, which can lead to maternal mortality, and support the birth of healthy children.

Infant mortality is the death of the child at birth or shortly after, while maternal mortality is the death of pregnant women during pregnancy or shortly after delivery.

Therefore, ensuring early and adequate prenatal care is the best factor that must be put in place to address the issue of maternal mortality and infant mortality rate.

All pros when conducting a lab experiment except?

Mrac [35]

Answer:

I personally believe that lab experiments are useful and an effective way to test and gather data. Even though they can often lack ecological validity and mundane realism they can easily be replicated and results can be retested, helping to prove/disprove data, ultimately leading to the creation of practical applications.

That psychologist can make statements about cause and effect because they involve the deliberate manipulation of one variable while trying to keep the other variables constant, unlike non-experimental methods.

Lab experiments can also be replicated due to the standardised procedures and measures, ultimately making it easier to check the reliability of the research/results and prove/disprove results if the research is conducted by another researcher.

Solar cells harness the sun's energy and convert it into electricity. However, the cost of this clean energy is much higher than

Dafna11 [192]

Answer:<u> Option D </u>

Solar panels contain a very expensive element, i.e. silicon. This element is able to convert the solar energy into electric energy. The cost of the solar panel gets expensive because of this rare element. It is found in limited areas of the world. That’s why option D is correct. Coal is not used in solar panel, so option B is incorrect. Neither is wind energy, so option A is also incorrect. Water is also not used for exploiting solar energy, which makes option C a wrong answer.

What happens when the temperature of air decreases to the dew point or below the dew point

svet-max [94.6K]

When the temperature of the air becomes almost equal to the dew point the air becomes saturated and the relative humidity during this condition becomes 100%. If the temperature of the air decrease below the dew point the relative humidity will be 100% or exceeds 100%. This condition, when the temperature of the air decreases below the dew point is called supersaturation but most of the time the temperature of the air will be lower than the dew point.
