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.

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.

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.)
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.
I think the answer would be 1,or 2
