The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:

A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.

B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

C. Crossing over between homologous chromosomes during prophase I of meiosis.

D.  Replication of chromosomes prior to meiosis.

E. Independent alignment of different homologous pairs on the metaphase I spindle.

Answer:

The correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Explanation:

The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.

This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.

Thus, the correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Strike441 [17]

Activational effect is the correct answer.

Activational effect is an impermanent hormonal effect that leads to a change in physiological activity or behavior in both humans and adult animals. For instance, when testosterone levels rise in male songbirds they become more aggressive and tend to engage in courtship behavior. Also, a pregnant woman may get more emotional than usual due to an extra level of progesterone and estrogen during pregnancy.

What does photosynthesis produce? What are these products used for?
Doss [256]

Answer:

photosynthesis produces glucose which is stored as starch in the plant.

Explanation:

6H₂O + 6CO₂ -----> C₆H₁₂O₆ + 6O₂(as a waste product for plants)

Photosynthesis reduces carbon dioxide in the atmosphere which reduces the green house gasses in the atmosphere which reduces the green house effect.

Cystic fibrosis is a recessive genetic disorder that result from a defective gene on chromosome 7. For an individual to have sym
spin [16.1K]

Answer:

Cystic fibrosis is a genetically transmitted or heriditary disease.

Explanation:

In cystic fibrosis the lungs and the digestive system get effected. It causes the CFTR protein (Cystic Fibrosis Transmembrane conductane Regulator) to become dysfunctional. Due to this dysfunction, chloride become unable to move.  for this reason mucus clogs the airways in the lungs which leads to respiratory failure and other complications. The gene responsible of this disease located at the long arm of chromosome number 7. Of all ethnic groups, caucasians have the highest inherited risk of this disease.
