Answer: peristalsis
Explanation:it's the contraction and relaxation of muscles as the bolus moves down the oesophagus
Answer:
The answer is 46 chromosomes.
Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.
Explanation:
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.
Answer:
The correct answer is D. FADH2
Explanation:
The glycolysis reaction that takes place is:
Glucose (C6H12O6) + 2 ADP + 2 Pi + 2 NAD ⟶2 Pyruvate (C3H4O3) + 2 ATP + 2 NADH + 2 H +
<em>Products: 2 Pyruvate (C3H4O3) + 2 ATP + 2 NADH + 2 H +</em>
Answer:
the chromosome are found in the nucleus of a body cell in pair
