The answer is hox gene.
Hox genes are responsible for an embryo's body plan. They determine different body structures - legs, vertebrae, antennae, wings, depending on groups. Mutation in hox genes is serious mutation since it affects the early stages of embryo and consequently, normal development. If a mutation occurs in the hox gene for legs growth, the legs will not develop.
The answers are
1. nitrogenous
2. acid-base
3. fluid
Answer:
- The Island population likely has fewer alleles-that is versions of genes-than the mainland population.
A- Agree <u>B- Disagree</u>
- Genetic drift is more pronounced in the island population than in the mainland population in these first few generations
A- Agree <u>B- Disagree</u>
- Some harmful traits may have become more common in the island population than in the mainland population
<u>A- Agree</u>- B- Disagree
- Biologist observed genetic drift but not evolution
<u>A- Agree</u> B- Disagree
Explanation:
If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.
The right option is; A. Prokaryotic cells have a nucleus
''Prokaryotic cells have a nucleus'' is the statement about prokaryotic cells that is NOT true.
Prokaryotic cells are cells that lack a true nucleus and some other cell organelles. Prokaryotic cells are found in unicellular organisms called prokaryotes. Examples of prokaryotes are; Bacteria and Archaea. The components of prokaryotic cells include plasma membrane, cell wall, cytoplasm, nucleoid, ribosomes, DNA (deoxyribonucleic acid). Most of the prokaryotic’s DNA (genetic material) is located in a middle area of the cell (nucleoid), and it contains a single large loop known as a circular chromosome.
