Which is an example of genetic diversity? PLS HELP temperate rain forest and a tropical rain forest bees, jack rabbits, diamondback rattlesnakes bacteria, garter snakes, tigers variations in a flock of starlings

Answers

Answer:

temperate rain forest and a tropical rain forest bees.

Explanation:

The temperate rain forest and a tropical rain forest bees is the example of genetic diversity because the same organisms has different features which allows them to live in different climatic conditions due to their variation in genetics. The environment of temperate rain forest is different from tropical rain forest so the bees specie that live in both environment are different from one another in their genetic makeup and which is an example of genetic diversity.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated

Answers

A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.

What is Mutation?

A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.

According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.

A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.

Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

Which of the following helps a species adapt to a changing
environment?
A Having fewer offspring
B Having more offspring
C Decreasing genetic variation
D Increasing genetic variation

Answers

Answer:

D

Explanation:

I think it is D because if you increase your genetic variation then you will have more population of, well "yourself" - therefore making more chances to survive. although don't take what I say word-for-word because I'm just a noob at this stuff. if it pops up wrong, please notify me why it is wrong so that I can improve.

By increasing genetic variation will help a species adapt to a changing environment. Therefore, the correct option is D.

What is genetic variation?

Genetic variation refers to the diversity of genetic information within a population or a species. It is the result of differences in the DNA sequences of individuals, which can arise through a variety of mechanisms such as mutations, genetic recombination, and gene flow.

It provides the raw material for natural selection to act upon. In a changing environment, individuals with certain traits may have a higher chance of survival and reproduction, and their traits may become more prevalent in the population over time.

Therefore, increasing genetic variation through mechanisms such as mutation, genetic recombination, and gene flow is critical for a species to adapt and survive in changing environments. Hence,  the correct option is D.

(Will give brainliest if correct and no links) Based on the image in figure 2, would the creation of one type of kidney cell be sufficient in forming a functioning kidney? Explain why?

Answers

Answer:

Yes.

Explanation:

The creation of one type of kidney cell will be sufficient in forming a functioning kidney because one type of cells allow the kidney to perform its one function i.e. filtering of blood. Epithelial stem cells are the cells that is responsible for the function of a kidney. The kidneys have only epithelial stem cells which performs only one function which removing water material, excess salts and water from the body. so we can say that one type of kidney cell is sufficient for the functioning of kidney.

Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. They were both below normal. The hemoglobin was normal, and the hematocrit was below normal. They were both normal. The hemoglobin was below normal, and the hematocrit was normal.

Answers

Answer:

The hemoglobin was below normal, and the hematocrit was normal.

Explanation:

Hemoglobin is an essential protein in the bloodstream, as it is primarily responsible for the transport of oxygen throughout the body. It is also responsible for the red coloration of the blood, as it is present in the red blood cells. The hematocrit, in turn, is a laboratory parameter to determine the amount of red blood cells in the blood and also to determine the total blood volume.

Although the results presented by the hematocrit are important in determining whether a person has anemia, women with normal hematocrit values may be anemic, primarily because the hematocrit results may be associated with the amount of water in the blood. What is essential to determine if a woman is, in fact, with anemia, due to iron deficiency, is the hemoglobin values that are below normal.
