Answer 1

Answer:

"Segmental deletion" seems to be the correct answer.

Explanation:

A special sequence range of approximately [tex]1\times 10^6[/tex] bp scattered segmental transposable elements containing DNA over a system or zone of [tex]2\times 10^6[/tex] bp edge. About [tex]1.6\times 10^6[/tex] bp, including that of the special sequence DNA, is destroyed if recombination happens between some of the segmental duplications.

Describe limits to cell division.

Answers

Answer:

All cells in the body have this internal control and most cells only divide between 50-70 times before they stop or die.

The study of cells is called cell biology.

The cell theory is given by Rudolf Virchow

The postulates of a cell theory are as follows:-

All the organism is made up of cellThe structure and the functional unit of life is the cell.All the pre-existing cell is made up of old cell.

The limits of the cell division are cancer cells. The cancer cell does not stop after a limit. It divides continuously and forms a tumor.

Hence, the correct answer is a cancer cell.

How are cancerous cells different from normal cells?

Answers

Answer:

Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.

Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a tree. Sunlight shines only three months out of the year. A stream supplies an abundance of water in a forest.

Answers

Answer:

Sunlight shines only three months out of the year.

Explanation:

I think this is right

Because abundance means a large amount so there would be no competition there.

If organisms share a place to sleep then that means no competition

If a living thing is consuming berries on a tree then the living thing is just eating

But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.

The statement that describes competition in an environment is option B a living thing consumes berries on a tree. Thus, consuming berries on a tree is reducing the availability of the food for other livings depends on the berries.

What is survival of living things?

In the nature, the concept that survival of the fittest domintates. The organisms which are fit physically and are smart to gather food will survive in the nature otherwise they will extincts.

An ecological community is a collection of populations of at least two distinct species that interact both directly and indirectly in a specific geographic area. Within this community, diffrent organisms can be found .

Numerous ecological characteristics and functions, including nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can have a variety of different natures.

Because of this, ecological interactions between particular individuals and entire species are frequently difficult to identify and quantify and depend on their scale and context they face extinction. Hence, option B is correct.

According to the image, the approximate QT interval is 0.4 seconds.

Explanation:

The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.

Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.

In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:

    0.04 seconds X 10 mm = 0.4 seconds.

Then, the estimated QT interval is 0.4 seconds.

a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns

Answers

Answer:

a. the primary transcript

Explanation:

The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.

Answers

Answer:

Budding

Explanation:

It is asexual reproduction in which offspring grows out of the parents organisms.

In the process of budding, an offspring grows off from the body of a parent organism and buds off when fully matured. Thus, the correct option is B.

What is Asexual Reproduction?

Asexual reproduction is the type of reproduction only a single parent is involved. In this process, offspring are developed from a single parent called mother cell and these offspring are genetically identical to the parent hence are also called as clones.

During the process of budding which is a types of asexual reproduction, a new organism develops from an outgrowth or bud which is formed on the parent plant due to the cell division at a particular site on the parent plant. For example, the small bulb-like projections coming out from the yeast cell are the buds which give rise to new yeast organism.

 

Therefore, the correct option is B.

Answers

Answer:
