Mendelâs main assumption is that a specific unit of heredity called the _____________ causes a specific observable trait in an o

anygoal [31]

Answer:

Factors

Explanation:

Mendel was a scientist who proposed the theory of inheritance based on his work done on pea plants.
According to his theory, the inheritance of a trait was determined by discrete and specific units of heredity which he called as factors.
Further, he explained that for any given trait each individual possesses one factor from each parent so that the individual has 2 factors for each trait and the variants of a given factor were termed as alleles.
The units of inheritance that were called as factors by Mendel are now termed as genes and it is the expression of these genes that encode for the observable trait in an organism and these are inherited from the parents.

In an effort to control vegetation overgrowth, 100 rabbits are released in an isolated area that is free of predators. After one

suter [353]

Answer:

It will plateau and the population will stabilize in relationship to available resources.

Explanation:

Having an unhinged rabbit population with no predators and an abundance of food will cause the population to initially increase. This increase will be due to an environment free from predation and also encouraged by an abundance of food.

In time these rabbits will increase in number and will put a strain on food supply. Dwindling resources will put pressure on reproduction. In addition to this these have a limited gene pool since they have been only reproducing with each other. This will pass along any disease sensitivity that they may have. In the even that a disease is introduced into the population many of them will be wiped out.

In conclusion, without a constant food supply to support a growing population the rabbit population will not multiply exponentially, indefinitely.

12. Which of the following information is given to participants in clinical trials as part of obtaining informed consent?

quester [9]

The correct answer is B. Possible side effects of a new medical treatment or product.

Explanation

A side effect is a concept that refers to the effect that a drug or treatment produces on the patient. Generally, when a drug is produced, a clinical trial is necessary to prove its effectiveness. This requires the participation of several volunteers who will test the drug and verify its effectiveness. However, these clinical trials have risks for volunteers since they can bring them negative effects because they are going to test drugs that have never been used before, so they must give their consent through a document called "informed consent. "where the volunteer is informed about the possible risks that the clinical study may have on him and if he is willing to undergo the test. Therefore, one of the main topics discussed during an informed consent is the possible side effects that the clinical study can bring to inform the volunteer of these conditions and confirm that he agrees with them. Therefore, the correct answer is B. Possible side effects of a new medical treatment or product
