Answer:

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution
Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

<u>The cell contains a </u><u>more concentrated solution</u><u> than the solution in the container</u>. The difference in concentration would produce an <em>osmotic gradient</em> that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

The sympathetic chain contains a group of cell bodies called the sympathetic chain Blank 1. Fill in the blank, read surrounding
lions [1.4K]

Answer:

The sympathetic chain contains a group of cell bodies called the sympathetic chain GANGLIA. This structure contains a second cell body for the sympathetic nervous system, the first in the series being found in the THORACOLUMBAR REGIONS' lateral horn of spinal segments T1-L2. The purpose of the VENTRAL AND DORSAL rami is to carry visceral motor and visceral sensory neurons to and from this sympathetic chain.

Explanation:

The sympathetic trunks (sympathetic chain, gangliated cord) are a paired bundle of nerve fibers that run from the base of the skull to the coccyx.

The relationship between catabolism and anabolism is most similar to the relationship between which of the following pairs of te
MrMuchimi

Answer:

The pair of terms whose relationship is very similar to the relationship between catabolism and anabolism are exergonic and endergonic.

Explanation:

Anabolism and catabolism are processes that occur in matabolism, whose result is different.

  • <u><em>Anabolism </em></u><em>involves all the processes of manufacture or synthesis, in which chemicals are bound together to form new compounds. This process consumes energy, so it is called </em><em>endergonic</em><em>. </em>
  • <u><em>Catabolism</em></u><em>, unlike anabolism, is the process of degradation of complex molecules into simple molecules. One of the results of catabolism is the release of energy, which is equivalent to saying that it is an </em><em>exergonic</em><em> process. </em>

Relating catabolism to anabolism is similar to relating exergonics to endergonics.

  <em>  The other terms do not represent a similarity with the relationship between the processes of catabolism and anabolism.</em>

Select the correct answer from each drop-down menu.
chubhunter [2.5K]

Answer:

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).
