Answer:

The correct answer is C. be more likely to have cancer at some point in his/her life.

Explanation:

Cell cycle checkpoints are controlled by different proteins which are coded by different genes. They are important in cell cycle regulation and stops cell cycle immediately if they find any problem in the cell like mutation.

The cell cycle will not be continued if the problem does not solve and cell death will occur which prevents cancer by preventing the mutation to spread into new cells.  

Therefore if a mutation occurs in certain genes that enforce a checkpoint on the cell cycle then the mutated gene will pass in new cells and the mutated cells will grow uncontrollably due to no checkpoints so the person will probably have cancer at some point in his or her life.

Nonspecific permeases a. allow a variety of molecules to cross the cytoplasmic membrane. b. allow only water to cross the cytopl
andriy [413]

Answer:

a. allow a variety of molecules to cross the cytoplasmic membrane

Explanation:

The cells have different molecules in its membrane. As a membrane the main function of it is to regulate the income and outcome of substances that the cell needs or the cell has like some wastes.

Some of these molecules can be some proteins like the permeases, that is going to  regulate the solutes that can enter the cell, but since they are non specific, that means that can not make the difference among one carbohydrate and another (as an example).

What would happen if cytokinesis did not occur?
12345 [234]

Answer:

Cytokinesis takes place in both meiosis and mitosis and performs the separation of he cell in half and form one nucleus into each daughter cell.

If cytokinesis did not happen, it will from multinucleated cells which means that their will be multiple nuclei in single cell and cell will not get separate in half, and no new daughter cells will form.

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>

Which best describes Darwin's studies that led to the theory of evolution?
ddd [48]

Answer:

The answer is B, extensive research of an individual organism over many years.

Explanation:

The question is asking, what best describes Darwin's studies that led to the theory of evolution, it would be a lot of research over a long period of time. Think, if you were to do a school project, would you get your best results over a short or long period of time with little or a lot of evidence/research? So, B is the best answer, I believe.
