The role of the cell membrane is most like the job of which person?

Answers

It has a job similar to a police officer who allows select people to enter and leave a crime scene.

Explanation:

The primary purpose of the cell membrane is to preserve the cell from its surroundings. The cell membrane manages the movement of materials in and out of cells and organelles. In this form, it is selectively perforable to ions and organic molecules. It is the same as of police officer or security guard that check the people and allow only a few to enter a specific place.
It has a job similar to a police officer who allows select people to enter and leave a crime scene.

A researcher creates random copolymers of three nucleotides by mixing polynucleotide phosphorylase with guanine and adenine nucleotides in a ratio of 5 guanine nucleotides to 1 adenine. Which of the following three nucleotide copolymers would most likely be most abundant? A. GGG D. GAA E. AAA B. GAG C. AGA

Answers

The answer is A. GGG.

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied.

If a ratio is 5 guanine to 1 adenine, this means that the possibility of adenine to be created is (1)/(6), and the possibility of guanine to be created is (5)/(6).

Now, we will use the multiplication rule to calculate the possibility of creation each of these 5 copolymers:
GGG - (5)/(6) × (5)/(6) × (5)/(6) = 0.58
GAA - (5)/(6)  × (1)/(6) × (1)/(6) = 0.02
AAA - (1)/(6)  × (1)/(6) × (1)/(6) = 0.005
GAG - (5)/(6)  × (1)/(6) × (5)/(6) = 0.12
AGA - (1)/(6)  × (5)/(6) × (1)/(6) = 0.02

According to this, the greatest possibility to be created has copolymer GGG.

Which of the following statements is a hypothesis?A) There are more calories in french fries than in colas.
B) If a student buys a meal plan, he or she will eat more vegetables.
C) Ginny gained 5 lbs her freshman year.
D) I like my biology class better than my other classes.
E) Blake failed the test.

Answers

Answer: B) If a student buys a meal plan, he or she will eat more vegetables.

Explanation:

Hypothesis is a statement(s) which is based on the assumption that is dependent upon the observations made before the research. The statement of the hypothesis can be tested based upon scientific methodology and can be identify as true or false based on the evidences obtain after the results of the experimentation.

B. is the correct option, this is because this can be tested and analyzed based on the identification of type and concentration of vegetables present in the meal.

How do animals obtain the nitrogen they use to make proteins and nucleic acids? A. by consuming plants or other animals B. by absorbing ammonia from bacteria growing in the roots of plants C. by breathing the nitrogen present in the atmosphere D. by absorbing nitrogen found in the soil

Answers

The answer is A. by consuming plants or other animals. Organisms need nitrogen to make proteins and DNA. However, they cannot directly use nitrogen from the atmosphere. Thus, choice C. is incorrect. Most plants absorb ammonia from bacteria growing in the roots or from the soil. On the other hand, animals get nitrogen by consuming plants or other animals.

In minks, the gene for brown fur (B) is dominant to the gene for silver fur (b). Which set of genotypes represents a cross that could produce offspring with silver fur from parents that both have brown fur?(A) Bb × Bb
(B) BB × Bb
(C) BB × bb
(D) Bb × bb
(E) none of the above

Answers

The set of Bb × Bb genotypes represents a cross that could produce offspring with silver fur from parents that both have brown fur. The correct option is A.

What is genotype?

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.

The clinical presentation of a patient is the observable expression of this genotype, or phenotype.

The brown fur gene (B) is dominant over the silver fur gene in minks (b).

The parents' phenotypic is brown, which indicates that they have at least one allele for brown fur (B).

While both parents have brown fur, the "bb" gene produces silver fur. The genotype "Bb" is shared by both parents, who are heterozygous.

Thus, the correct option is A.

The capitals are the dominant genes. The small b's are the none dominant genes. If it has a capital, the offspring is most likely to have brown fur as it is not as dominant. I hope this helped at all :)
