Assume that a recent study found that a chemical in a popular sports drink could cause a cell to undergo mitosis at an unregulat

ed rate. The researchers concluded that people should not drink this sports drink because it could lead to cancer. Which of the following is a valid response to this conclusion? I. What do chemicals in fruit juices do to cells? II. Which type of cell was used in the study? III. How much of the sport drink chemical were the cells exposed to? A. II only B. I only C. I and III only D. II and III only

The answer is D, II and III. It can depend on how much of the drink the cell was exposed to and what kind of cell it was.<span />

Answer:

The correct answer would be option D.

I statement would not be a valid response as it is the fact on which the conclusion was made.

On the conclusion provided, one should ask about the cell type used in the study and the amount of chemicals those cells were exposed to.

Different types of cells may response in different manner against a particular chemical. For example, stem cell would response in different manner whereas differentiated cell would response in different manner.

Similarly, the amount or concentration of chemical plays important role in any reaction or cellular response. For example, the affinity of haemoglobin is high towards oxygen in alveoli whereas it is high towards carbon dioxide in body cell.

So, the correct answer would be option D.

Are there any similarities between this Galapagos research and Darwin’s research? Explain your answer.
Usimov [2.4K]

Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.

Imagine that five hypothetical genes are arranged on a chromosome in the following order: G--H--I--J--K. Which two genes are mos
andrezito [222]

Answer:

G and K

Explanation:

Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.

This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.

In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
