Name one cell type that continues to divide throughout a person's lifetime and one that doesn't continue to divide throughout a

person's lifetime.

Otrada [13]3 years ago

So base on the question that states and ask to give the name of one cell type that continues to divide throughout a person's lifetime and also on who does not, with that question, the cell that divide through persons lifetime is a Mitosis or skin cells, an example to this is the skin, and the who doesn't divide is i think the brain cells, it doesn't regenerate

Which plant system is affected when xylem tissue is removed
Gennadij [26K]
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves. 

So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN
Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

  • <em>In any one species, the amount of adenine closely approximates that of thymine.  </em>
  • <em>In any one species, the amount of guanine closely approximates that of cytosine.  </em>
  • <em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA      A            T            G            C </u>

Streptococcus    29.8       31.6        20.5       18.0

Yeast                   31.3        32.9       18.7         17.1

Herring                27.8       27.5       22.2       22.6

Human                30.9       29.4       19.9        19.8

E. Coli                  24.7       23.6        26.0      25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

Connect the importance between meiosis and the process of sexual reproduction. Is it possible to survive without your reproducti
Aleksandr [31]
It must be known that there is an interdependent relationship between meiosis and sexual reproduction. During sexual reproduction, meiosis generates a genetic variation in the offspring because it randomly shuffles genes across chromosomes and then randomly segregates half of those chromosomes into each gametes. These two gametes or sex cells then fuse randomly to form a new organism. One of the key factors in evolutionary fitness and biological diversity is genetic variation. This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation.

To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.

Reproductive organs of both men and women are vital to create a child. But it must be noted that both can live without them. There are situations that sometimes necessitates the removal of such organs especially if he or she is inflicted with cancer or other diseases.
