Answer:

This is because through this technique;

  • The targeted animal with its unique traits and healthier properties can be developed through cloning.
  • Doctors believe this innovative techniques could help eliminate animal extinction as a whole and preserve animal species overtime.
  • It can help facilitate genetically modified medicines through cell manipulation and cloning.

Answer:

The Somatic Cell Nuclear Transfer technique has the potential to be used to reproduce extinct species.

Explanation:

Somatic cell nuclear transfer (SCNT) involves the nucleus from a somatic body cell being transferred to the cytoplasm of an enucleated egg (an egg that has had its own nucleus removed). Once the somatic nucleus is inside the egg it is reprogrammed by egg cytoplasmic factors to become a fertilized egg (zygote) nucleus. The egg is allowed to develop to the blastocyst stage where embryonic stem cells can be created from the inner cell mass of the blastocyst. Mouse, monkey and human embryonic stem cells have been made using SCNT.

Reproductive cloning occurs by implanting a SCNT derived blastocyst into the uterus of a surrogate mother, where the embryo develops into a fetus.

The SCNT technique was used to create the first cloned mammal, Dolly the sheep.

Given our understanding of genetics, we can confirm that the gene in question is of the homeotic type.

<h3>What is a gene? </h3>
  • In biology, we refer to a gene as the most basic unit of genetic information.
  • It is a segment of DNA that encodes for a certain trait that <u>may or may not be expressed.</u>
  • A gene carries the information for a specific trait, for example:

             1) Eye color

             2) Body organization

             3) Height

<h3 /><h3 /><h3>What does it mean for a gene to be homeotic?</h3>
  • In the case of this question, the gene in question is a homeotic gene.
  • Homeotic genes are those that are in charge of the organization of the organism's body.
  • These genes control the <u>general pattern of the body</u>, such as where the arms and legs will be, and so on.
<h3 /><h3 />

Therefore, given the definition of a homeotic gene, we can confirm that this is the type that best fits the description of the mutation in the question since it affected the formation and normal organization of the body.

How are contaminants magnified up the food chain?
rosijanka [135]

Answer:

Biomagnification also called food web magnification or food web accumulation is the progressive increase in the concentration of contaminants in organisms as the trophic level increases. These unexpectedly large concentrations are the result of DDT biomagnification up the food web.

Question 1

D

Question 2

C

Question 3

D

Explanation:

1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.

Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)

2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.

A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)

3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.

Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)

Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Doss [256]

The right answer is organelle G, which represents mitochondria.

Mitochondria is the place of cellular respiration. This is a set of reactions that convert glucose into the energy molecule, ATP. This process involves several steps, including the "Krebs Cycle", a set of metabolic reactions that takes place in the mitochondrial matrix. The enzyme that produces ATP is found in the inner membrane of the mitochondria. For these reasons, the mitochondria is often referred to as the cell's energy factory.
