A phosphate group of the nucleotide being added and the 3' OH of the final nucleotide in the polymer produce a phosphodiester link during the polymerization of DNA.

A condensation reaction is used to connect nucleotides, releasing a tiny, stable molecule as a byproduct. Unlike sugars, proteins, and lipids, the molecules that are expelled are not water but rather pyrophosphates, which are made up of two phosphate groups joined together.

A phosphodiester bond is created during the polymerization of DNA between a free 3 prime hydroxyl group at one end and a free 5 prime phosphate group at the other. These sequences' names range from 5 prime numbers to 3 prime numbers.

The bulk flow of fluids that occurs in capillary beds typically occurs across endothelial cell membranes. Therefore, option (c) is correct.

What is Fluids?

Fluids are substances that have the ability to flow and take the shape of their container. They include both liquids and gases, and are distinguished from solids by their ability to flow and deform in response to external forces.

Liquids are a type of fluid that have a definite volume but no definite shape, and they assume the shape of their container.

Gases are another type of fluid that have no definite shape or volume. They expand to fill their container and are compressible. Examples of gases include air, oxygen, and carbon dioxide.

Fluids play an important role in many biological processes, including blood flow in the circulatory system, digestion of food in the digestive system, and the movement of air in the respiratory system. The study of fluids is an important part of physics, engineering, and other sciences.

Bulk flow of fluids refers to the movement of large amounts of fluid and solutes across capillary walls. This process occurs primarily through a mechanism called filtration and reabsorption. Filtration occurs at the arterial end of the capillary bed, where blood pressure forces fluids and solutes out of the capillary and into the surrounding tissues. Reabsorption occurs at the venous end of the capillary bed, where fluid and solutes are taken back into the capillary from the surrounding tissues due to the osmotic pressure difference.

The area of physiology known as endocrinology is focused on how the endocrine system and the hormones produced by these glands work. In light of this, endocrinology does not focus on the investigation of how the neurological system or nerve cells operate.

Biology and medicine's field of endocrinology focuses on the endocrine system, disorders that affect it, and the distinct hormone discharges that emerge from it. The integration of developmental processes like proliferation, growth, and differentiation as well as psychological or behavioural actions like metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception brought on by hormones are also taken into consideration.

A colony is a mound of cells on a solid medium that represents the progeny from one original bacterial cell. Thus, the correct option for this question is A.

A bacterial cell colony may be characterized as a collection of bacteria that are derived from an identical mother cell. This reveals that a single mother cell reproduces in order to construct a group of genetically identical cells.

The methodology of diverging a single bacterial cell from other cells and delivering it space on a nutrient surface will allow that cell to grow into a mound of cells. This is known as a colony. If formed from a single cell, the colony contains cells from just that species.

Erythematous mucosa in the gastric body and antrum is called gastritis.

Your digestive tract is lined on the inside with a membrane called mucosa. Redness is erythematous. Thus, having erythematous mucosa suggests that your digestive tract's inner lining is red.

The area of the stomach before the outflow known as the antrum is mucosa-lined and does not create acid.

The lower portion of the stomach, or the antrum, can occasionally be the only area of gastropathy. Gastritis typically affects the entire stomach. Gastritis can be persistent or short-term (acute) (chronic).

Skeletal muscle has striae, cylindrical cells, and many nuclei.

Since it lacks sarcomeres and as a result, striations, smooth muscles are considered involuntary non-striated muscle (bands or stripes). Single-unit smooth muscle and multiple - unit smooth muscle are its two subgroups. The whole sheet or bundle of smooth muscle cells that make up a single-unit muscle contracts as a syncytium.

Answer:

a heart attack

Explanation:

The distortion observed when using a light microscope at the highest levels of magnification is reduced by the use of immersion oil. Here option B is the correct answer.

Immersion oil is a type of oil that has the same refractive index as glass, the material used to make microscope lenses, and is placed between the slide and the objective lens.

It helps to reduce the refraction and scattering of light as it passes through the sample, leading to clearer and more accurate images. The use of immersion oil improves resolution, contrast, and brightness, which are essential for the accurate observation and identification of microscopic structures.

The other options listed do not reduce distortion. A lens with a smaller numerical aperture would provide less light, leading to a darker image, while using a longer wavelength of light would decrease resolution. Finally, using a lower-power objective lens would decrease magnification and make it difficult to observe small structures.

Interphase has three stages. G1, S and G2. During S stage of the interphase, the chromosome replicates, so that the DNA is doubled.

Interphase is the stage between two cell division. The daughter cells formed grow and doubles the amount of DNA during this phase. As it was not visible under microscope it was earlier termed as resting phase. But since all the process that lead to cell division happens during this stage, it was renamed as interphase.

In G1 phase of the interphase the daughter cells grows and protein synthesis for replication occurs. The daughter cell will have 12 chromosomes and 12 chromatids during this stage. During S-phase the chromosomes are replicated. Each chromosomes will now have two sister chromatids. Thus the DNA is doubled. It will still have 12 chromosomes, but have 24 chromatids. During G2 phase, the proteins required for mitosis are produced.

So even if the cell remains diploid, the chromosomes are replicated to form two sister chromatid to facilitate cell division.
