Answer:

The Mendelian trait are those controlled at only single gene locus. The Mendelian trait have two alleles (one form each parent), out of which one allele is dominant while the other is recessive. ... An example of the human Mendelian trait is the attached or detached earlobes.Feb 11, 2016

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

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.

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.

Plants make their own food and are called producers. What do plants need to make their own food? A) soil, air and water B) soil,

djyliett [7]

Answer:

D) energy from the sun, air, and water

Explanation:

Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.

For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+ $6CO_2 + 6H_2O$ . In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.
