1. Explain how DNA is replicated?

Answer:

C is the correct option.

Explanation:

The muscle's increase active force grows until it reaches its maximum length before falling. The length at which the heart typically beats is at this maximal point.

For a muscle cell to contract, the sarcomere must shorten. However, the thick and thin filaments that make up sarcomeres do not get any shorter. Instead, they move past each other, shrinking the sarcomere but maintaining the original length of the filaments.

There is a perfect distance between sarcomeres where the tension in the muscle fiber is highest and the force of contraction is greatest. There will be a decrease in contraction tension and strength if sarcomeres are located either closer together or farther apart than this ideal length.

Proteins are mostly absent from glomerular filtrate except for a small protein called albumin. Glucose and amino acids are reabsorbed from the glomerular filtrate by the proximal convoluted tubule.

Glomerular filtration is the mechanism by which the kidneys filter the waste products and other components from the blood into the glomerulus, which is required to maintain body homeostasis. Glomerular filtration is caused by the pressure gradient in the glomerulus, thereby an increase in blood pressure also increases the glomerular filtration rate.

The most important components in the filtrate (such as amino acids and glucose) are reabsorbed by the first half of the proximal convoluted tubule. In conclusion, glucose and amino acids are reabsorbed from the glomerular filtrate by the proximal convoluted tubule. The proximal convoluted tubule avidly reabsorbs filtered glucose into the peritubular capillaries so that it is all reabsorbed by the end of the proximal tubule.

Answer:

Diffusion

Explanation:

Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space.

A passive form of transportation is diffusion. When a space's concentration is uneven throughout, a single substance has a tendency to shift from a high concentration to a low concentration area.

Because the biochemicals are moving from an area of higher concentration to a region of lower concentration, energy is not needed to transport the molecules in this biological process.

Passive transport is the method used to move any easily soluble particles.

As a material diffuses, it moves from places of high concentration to areas of lower concentration. This process goes on until the substance is dispersed equally throughout the system.

Therefore, When the concentration is unevenly distributed throughout the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration.

Answer:

"F" on account of E.coli show the fertility factor. Cells possessing this factor (called donors) hold the ability to move the hereditary material over the strains by a procedure called conjugation. F-factor exists as a free element (cell is called episome) or integrated into bacterial chromosome (cell is called Hfr-High frequency recombinant). Cells with no F factor are recipients.

In a Conjugation between a F+ and F-cell just F factor from F+ cell gets moved o produce two F+ cells. But during a Hfr and F-conjugation as the F factor is incorporated into the chromosome and by the intrinsic idea of F factor to get moved the Hfr cells attempt to move their whole genetic material across and there are two outcomes wherein one case there is a fragmented exchange of hereditary material and the recipient cell remain F-and when there is a finished exchange of hereditary material the cell becomes Hfr yet this is uncommon as the time taken for the total exchange of hereditary material is excessively long for the cells to remain contact.

Answer:

Transcription and replication are important processes that occur in cells but have distinct differences.

Similarities between transcription and replication:

1. Both transcription and replication involve the synthesis of nucleic acids. In replication, DNA is copied to produce an identical DNA molecule, while in transcription, DNA is used as a template to produce RNA.

2. Both processes occur in the nucleus of eukaryotic cells, although replication also occurs in the cytoplasm of prokaryotic cells.

Differences between transcription and replication:

1. Template: In replication, the entire DNA molecule serves as the template for copying. However, in transcription, only a specific DNA segment, called a gene, serves as the template for synthesizing an RNA molecule.

2. Product: Replication results in the production of an identical DNA molecule, while transcription produces an RNA molecule that is complementary to the DNA template.

3. Enzymes involved: Replication requires the involvement of multiple enzymes, including DNA polymerase, helicase, and ligase. Transcription, on the other hand, involves RNA polymerase, which catalyzes the synthesis of RNA from the DNA template.

4. Base pairing: During replication, DNA bases pair with their complementary bases (A with T and C with G) to produce an exact copy. In transcription, RNA bases pair with complementary DNA bases (A with U and C with G), resulting in an RNA molecule complementary to the template DNA strand.

Overall, while transcription and replication involve the synthesis of nucleic acids, they differ in terms of their templates, products, enzymes involved, and base pairing patterns. These processes are essential for cell function and crucial in genetic information transfer and maintenance.

Option 2. "Diffusion moves carbon dioxide in the atmosphere to the oceans, and the sea plants use carbon dioxide for photosynthesis."

Explanation:

This statement describes two processes in the carbon cycle. First, carbon dioxide moves from the atmosphere to the oceans through diffusion. Once in the oceans, carbon dioxide can be taken up by sea plants during photosynthesis, in which carbon dioxide is used to make organic molecules like sugars. These organic molecules are then consumed by other organisms in the ocean, and the carbon is passed along the food chain. This process represents one path that carbon dioxide can take through the carbon cycle.

Answer: Capillaries pass oxygen and waste between blood and cells.

Explanation: Capillaries are very thin-walled tubes that connect the arteries to the veins. The walls of these tubes are only one cell thick. Capillaries are found everywhere in the body. These thin tubes allow the food, oxygen, and waste to move between the bloodstream and cells. Waste products pass into capillaries and are carried by the veins to be disposed of in other parts of the body. Capillaries are the only blood vessels thin enough for materials to pass back and forth between cells and blood.

Blood Capillaries pass oxygen and waste between blood and cells. Thus option A is correct.

Capillaries are small type of blood vessels where a single red blood cell can barely fit in them.

Answer: The daughter cells develop after the cell division will have unequal number of chromosomes.

Explanation:

The interphase is the stage of the cell cycle in which the parent cell prepares itself for division. It increases in size and develops organelles for cell division. Before the cell division the replication of the genetic material in the form of DNA is necessary so that both daughter cells receive equal amount of genetic material after the cell splits by mitosis. Mitosis is a cell division in which the parent diploid cell splits into two haploid daughter cells. Each daughter cell receives the half the chromosomes as that of the parent cell.

Explanation:

Hope it helps you!

Answer:

Active transport

Explanation:

Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
