Answer:

Heart disease is a non communicable disease because it does not happen due to any virus or bacteria.

Explanation:

Diseases caused due to virus and bacteria are mostly communicable. Heart Disease is caused due to poor supply of nutrients in hearts.

It can not be transferred between pathogens.(bacteria etc.) it is a biological disfunction passed on either through poor habit of food intake, or its genetic. It's the scenario in which abnormal amounts of fat is in your blood vessels and clogs up your vein and stops the flow of blood. It's a disease relitive to the persons habits, and cannot be transmitted like corona.

determine the ratio of average maximum elongation rate for the modified RNA polymerase compared to the wild strain RNA polymeras
Vinil7 [7]

Answer:

Check the c in the explanation

Explanation:

a) RNA has three components - 1) 5 - carbon ribose sugar (2) phosphate group (3) nitrogen base

RNA polymerase is an enzyme involved in transcription where genetic material DNA is transcribed into RNA ( mRNA,rRNA,tRNA).

b) the dependent variable here is what we are looking in the experiment , here it is number of nuceotides per second ,the transcription efficiency of RNA polymerase. And the two controls are important wild type without drug and experimental strain without drug these two tells about baseline of transcription rate of an enzyme. so that one can explain the drug effect on a enzyme.

c) In both wild type and exp strain upon treatment with amanitin the transcription rate decreased in exp strain it is not significant whereas in wild type the effect is much higher compare to exp strain and it is significant. this suggests that the mutation in experimental strain must be on larger subunit of the RNA pol enzyme. that mutation might be showing effect of binding drug to the enzyme and also has a role for its enzyme activity.

and the reduction of transcription rate is 100% efficient in wild type compared with exp strain.

d) a null hypothesis is a general statement in a statistics where there is no measured phenomenon between groups.

the change in the amino acid is an important clue, tells that there is no effect in transcription rate between experiment strain with and without drug . which in turn tells that the mutation is imp for the activity of the Enzyme for its role.

A widows Peak is dominant over straight hairline the genotypes of The Offspring are WW, Ww, ww and ww. What are the phenotypes o
anastassius [24]

Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.

The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).

A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).

So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.

For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.

Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.

At the end of _____ and cytokinesis there are four haploid cells. At the end of _____ and cytokinesis there are four haploid cel
kotegsom [21]

Answer:

At the end of<u> telophase II </u>and cytokinesis, there are four haploid cells.cells.

Explanation:

During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.

We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
