Transposable elements make up 44% of the human genome. What is thought to be their function?

Biology
1 answer:
AfilCa [17]4 years ago
4 0

Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.

Explanation:

Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.

The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.

Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.

In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.

Which statement best describes cancer cells?
Ber [7]

The statement "they are not regulated by contact inhibition" best describes cancer cells. Thus, the correct option is D.

<h3>What is a Cancerous cell?</h3>

A cancerous cell may be defined as a cell that stimulated continuous growth, inhibition of apoptosis, perform metastasis, etc.

Contact inhibition is performed by the noncancerous cells to cease proliferation and growth when they contact with each other. This property is lost when any noncancerous cell is transformed into a cancerous cell.

Thus, the correct option for this question is D.

The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (hg) and a st
Damm [24]

Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.  

To find: P(100 < 152)

Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.

Solution:

Mean u = 152, std s = 18

Z score = \frac{X-u}{s} = \frac{100-152}{18} = -2.89

The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.

P(Z=-2.89) = 0.0019

The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.

Thus the probability of 100 mm Hg blood pressure is 0.0019.

How will wolf emigration affect a grassland ecosystem that supports rabbits, the wolf's primary prey?
svet-max [94.6K]

Wolf emigration will bring about the rabbit population increasing.

<h3>What is Emigration?</h3>

Emigration is defined as the movement of organisms away from a particular

area or habitat.

We are aware that Wolves feed on rabbits as a means of food in the

grassland ecosystem. This translates to the following below:

  • The greater the wolves the lesser the rabbit
  • The lesser the wolves, the higher the rabbit.

This therefore means that wolf emigration will bring about the rabbit

population increasing which makes option B the most appropriate choice.

Why does it benefit an imperial shrimp to travel on a sea cucumber?
olasank [31]

Answer:

the imperial shrimp and the sea cucumber have what's referred to as a one sided symbiotic relationship. that's a type of relationship where there's two organisms, but only one of those organisms benefit. the other organism isn't helped, but it isn't hurt, either.

<u>an imperial shrimp benefits from its relationship with the sea cucumber because the shrimp, when hungry, can get a lift on his lil friend the sea cucumber and is dragged around the ocean to where there's food for shrimp to eat :)</u>
