During the cell cycle, the cell must pass through several checkpoints that confirm that the cell is ready to progress to the nex

t phase of the cycle. If the requirements of one phase have not been met, the cell cannot proceed to the next phase. These checkpoints help control the rate of cell division. If a mutation disables one of these checkpoints, what is most likely to happen?
a. Cells proceed through phases of the cell cycle in the wrong order
b. Cells remain in one phase of the cell cycle for the rest of their existence
c. The cell begins dividing too often, forming a tumor
d. Cells divide slowly, reducing organ function.

Answer:

The answer is C

Explanation:

The cell begins dividing too often, forming a tumor. Since there is no check due to mutation, cell growth and death is not controlled hence the cells divided too often and as they like leading to tumour development and cancer.

In a population of grasshoppers, the color green (G) is completely dominant over the color brown (g). If 23% of the population i
barxatty [35]
The answer is 49.92%

Let's use the <span>Hardy-Weinberg principle:
p + q = 1
p</span>² + 2pq + q² = 1
<span>
where:
p - the frequency of dominant allele G
q - </span>the frequency of recessive allele g
p² - the frequency of homozygous dominant individuals GG with colour green
2pq - the frequency of heterozygous individuals Gg with colour green
p² - the frequency of homozygous recessive individuals gg with color brown

23% of the population is brown: p² = 23% = 0.23
p = √(p²) = √0.23 = 0.48

p = 0.48
p + q = 1
0.48 + q = 1
q = 1 - 0.48 = 0.52

<span>The percentage of the population that is expected to be heterozygous is 2pq:
2pq = 2 * p * q = 2 * 0.48 * 0.52 = 0.4992 = 49.92%</span>

aleksandrvk [35]

Answer:

C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation

Explanation:

Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.

Why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body?
marissa [1.9K]

Answer:

Because it prevents venous blood from mixing with arterial blood (which is rich in oxygen), in this way the circulation is more efficient.

Explanation:

In land vertebrates, the blood circulation is structured in two independent circuits: the pulmonary circulation, where oxygenation of the blood occurs and the elimination of the carbonic anhydride that it contains, returning back to the heart through its left atrium; and the systemic or major circulation, impelled from the left ventricle, transports the oxygenated blood and the nutrients that it assimilates as it passes through the digestive system, to the tissues of the animal, where it is charged again with anhydride carbonic and other waste substances, returning back to the heart, where it enters through the right atrium. These systems are independent and prevents venous blood (which is poor in oxygen) from mixing with arterial blood. These systems are independent and prevents venous blood (which is poor in oxygen) from mixing with arterial blood.

Before performing an mri, why must technicians ask patients if they have any steel inside their body?
elena-14-01-66 [18.8K]
The technicians ask the patients if they have any steel inside their body because the steel when subjected to a magnetic field they will become a magnet. since MRI produces a very large amount of magnetic field during its operation, then the still will be a magnet and it might hurt you
