Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Brothymol blue turns from blue to yellow in the presence of CO2.
Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?
Answer:
Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.
The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.
Gonads are the reproductive organs that produce gametes.
Gametes are also known as sex cells. They are produced by the gonads. In males, the gonads are the testes. The gametes that are produced by males are called sperm cells. In females, the gonads are the ovaries. The gametes that are produced by females are called egg cells.
Answer:
<u>B) Polycystic kidney disease</u>
Explanation:
<u>A) Hypospadias</u>
It is a congenital disease characterized by an abnormal urethral opening on the dorsum of penis.
<u>B) Polycystic kidney disease</u>
It is a disease characterized by the multiple cysts in the kidney as implied by the name.
<u>C) Cystitis</u>
It is defined as the infection of urinary bladder.
<u>D) Dysuria</u>
It is defined as painful urination. It can be due to infection or other underlying disease.
<u>E) Epispadias</u>
It is a congenital disease characterized by an abnormal urethral opening on the ventral surface of penis. It is much less common than hypospadias.
<u>CORRECT ANSWER</u>
From the options, the most appropriate answer is <u>B) Polycystic kidney</u> as it is a disease characterized by the formation of cysts in the kidney. These cysts obstruct urinary flow.
