Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced by
these two plants all had the dominant trait. The Punnett square showed that there was a 50 percent
chance of the offspring carrying rr genes. So, the student assumes that he made an error in determining
W the genetic makeup of the plants. Do you think the student made an error, or is there another
explanation?

Answers

Answer 1

No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.

I hope that helps and makes sense!

Answer 2

Answer:

No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.

plz help!!!!!!!! A natural biological cooling process is sweating. Using your knowledge of endothermic and exothermic, explain why your body feels cooler when it sweats.

Answers

Answer and Explanation:

An exothermic reaction takes place when heat flows out of a system into its surroundings. ... When you sweat, the system – your body – cools down as perspiration evaporates from the skin and heat flows to the surrounding area. This means sweating is an exothermic reaction.

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.​

Answers

Answer:

pRNA is the product of chemically linked amino acids.​

Explanation:

All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.

There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.

When are two populations likely to have very similar allele frequencies?

A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow

Answers

Answer:

c). If there was a large amount of genetic drift.

If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.

What causes allele frequencies to live equally?

Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.

What are two impacts of allele frequencies of a population?

The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.

A Quantitative

The answer is A. Quantitative because Quantitative is observing amount, or quantity. Qualitative would be observing the quality, like color or shape. Hypothetical is making a hypothesis on the size, and finally inferential is would be saying you measured the leaf, I believe. A quick way to solve this would be to see if it involves numbers, and if so it’s a quantitative observation. If it involves color or shape or anything you observe with sight alone, it’s a qualitative observation. I hope this helps and sorry for the long answer, just trying to explain why A is correct.
