Movement of the chromosomes during anaphase would be most affected by a drug that

1 answer:
My name is Ann [436]3 years ago

Answer:

The options are missing, the options are:

A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation

The answer is C

Explanation:

Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.

Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.

Answer:

Question 1

D

Question 2

C

Question 3

D

Explanation:

1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.

Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)

2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.

A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)

3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.

Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)
