The correct answer is option D. Prophase I
The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.
b. Your eyes react faster than your ears.
c. Light travels faster than sound.
d. Sound travels faster than light.
The sound is produced when the ball hits the air, that's when we see a baseball flying through the air before we hear the bat hit. So, the correct option is A.
Sound is defined as the vibration which propagates in the form of an acoustic wave through a transmission medium such as a gas, liquid or solid. Sound is described as the reception of such waves and their perception by the brain.
This is explained as the mechanical disturbance from a state of equilibrium which propagates through an elastic material medium. The sound is produced when the ball hits the air, that's when we see a baseball flying through the air before we hear the bat hit. Musical instruments also produce sound like the sound produced by guitar, sitar, harmonium etc. is musical sound or music.
Therefore, the correct option is A.

d. ascites.
The cytoplasm is where cellular respiration starts off. Here, glucose gets disassembled into smaller molecules. Additionally, a small amount of energy is released. The mitochondrion hosts the second stage.
The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration.
The Krebs cycle, the second phase of cellular respiration, happens in the matrix. On the inner membrane, electron transport occurs in the third stage.
Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.
What two anaerobic cellular respiration pathways are there? Instead, some species use anaerobic respiration, which doesn't need oxygen, to make ATP from glucose. Fermentation is a crucial method of producing ATP without the use of oxygen. Fermentation comes in two flavors: lactic acid fermentation and alcohol fermentation.
Where do aerobic phases occur? The mitochondrial matrix of the cell is where aerobic respiration takes place.

The first stage of cellular respiration occurs in the cytoplasm. This is where glucose is broken down into smaller molecules. A small amount of energy is also released. The second stage occurs in the mitochondria. This is where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy.
B) to observe whether or not a recessive trait would reappear
C) to observe whether or not the dominant trait would reappear
D) to distinguish which alleles were segregating
E) to be able to describe the frequency of recombination
Answer:
D. Mitosis involves only one division, while meiosis involves two divisions.
Explanation:
Mitosis and meiosis are processes of cell reproduction that happen in living beings. They originate cells for different purposes. Each mitosis produces two cells equal to the source. An meiosis creates four daughter cells with half the genetic material of the mother cell.
