6 0

Answer:

d. All of the listed statements are true.

Explanation:

Chromatin is presnet in the chromosome consist of protein and protein. histones are themajor proteins in chromatin that help in the compact packaging of the DNA in the cell nucleus.

<u>There are several problems posed by chromatin during transcription:</u>

  • During transcription, protein can interfere with the chromatin structure at specific locations and interefere with its structure.
  • Histone post-translation modifications (PTMs) regulate the structure of chromatin and also guide the remodeling enzymes which use the energy derived from ATP hydrolysis to reposition nucleosomes.
  • During replication the chromatin structure rearrange itself in order to make the new DNA fit inside the nucleus.

Hence, the correct option is d.

Answer:

D

Explanation:

This may seem difficult to answer at first, cuz A and even B sounds plausible, but the relative direction of where she's drawing the picture is not known. And we know that the sun does not rise and set in the same place everyday. So the best answer would be D

Which pharmacokinetic parameter is affected most by decreased intestinal motility related to the aging process? a. excretion b.
Tpy6a [65]
I believe the answer is <span>c. absorption

</span>The phase of pharmacokinetic that happens in the intestine is when the drug absorbed. A person with old age will have lower intestine motility. This will increase the transit time which will increase the amount of drug absorbed.

Age could also influence others pharmacokinetic parameter(<span>excretion, distribution, metabolism) but it is related with another organ, not intestine.</span>

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
Y_Kistochka [10]
Deletion is when a part of the chromosome is deleted. (Removed)
Insertion is when part of our chromosome has an extra bit added to it.
Translocation Is when one part of the chromosome is moved to another chromosome.

The correct answer is inversion, to invert means to turn upside down. So when part of the chromosome is taken off but attached backwards (turned upside down) we call it inversion

Hope that makes sense

3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
katen-ka-za [31]

Answer:

The plants have the higher population density. This is because, when compared with that of the insects, the number of plant species per acre area is higher; 2800 compared to 683.3

Explanation:

The number of individual species per unit area of land is known as the population density. Population density describes how crowded or spaced out a given species is in a particular area. The higher the population density, the more crowded the species are and vice versa. The formula for calculating population density is given as:

Population density = Number of species/land area

Population density of the insects = 820/1.2 = 683.3 insects/acre

Population density of the plants = 560/0.2 = 2800 plants/acre

Therefore, the plants have the higher population density.

This is because, when compared with that of the insects, the number of plant species per acre area is higher.
