DNA polymerase is an enzyme that is essential for DNA replication, or the process of replicating DNA molecules during cell division. The three distinct functions of DNA polymerase are as follows:

Polymerization, Proofreading, Repair

DNA polymerase's principal function is to catalyse the addition of nucleotides to the 3' end of a developing DNA strand. DNA polymerase has a strong affinity for the complementary nucleotide to the template strand, and it adds the nucleotide to the template in a complimentary way.

Proofreading: DNA polymerase undertakes proofreading during polymerization to guarantee that the proper nucleotide is added to the developing DNA strand. If an erroneous nucleotide is introduced, the DNA polymerase may identify the error and delete the faulty nucleotide before the polymerization process can continue.

Repair: By deleting and replacing nucleotides, DNA polymerase may repair damaged DNA. This process is known as nucleotide excision repair, and it is crucial for maintaining the genetic material's integrity. When DNA is damaged, DNA polymerase detects it and removes the damaged nucleotide before replacing it with the proper one.

Small, nonpolar molecules can diffuse across cell membranes through passive diffusion, which does not require the use of energy. Passive diffusion occurs when a substance moves from an area of higher concentration to an area of lower concentration, down its concentration gradient.

The cell membrane, also known as the plasma membrane, is composed of a phospholipid bilayer that separates the inside of the cell from the outside environment. The phospholipid bilayer consists of two layers of phospholipid molecules, each with a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophilic heads face outwards on both sides of the membrane and the hydrophobic tails face inward, forming a barrier that is impermeable to most polar and charged molecules.

In addition to phospholipids, the cell membrane also contains proteins that serve a variety of functions such as transporting molecules across the membrane, serving as receptors for signals, and helping to maintain the structure of the membrane. Carbohydrates are also present on the cell surface in the form of glycoproteins and glycolipids, which play a role in cell recognition and cell-cell communication.

Nonpolar molecules, which are also hydrophobic, can easily pass through the hydrophobic tails of the membrane.

Therefore, the small, nonpolar molecule would simply move from an area of high concentration outside the cell to an area of lower concentration inside the cell, down its concentration gradient, through the phospholipid bilayer of the cell membrane. This process is known as simple diffusion.

Plant roots can absorb nutrients from the soil and use them for growth, or they can go through different chemical and biological changes in the soil.

Plants employ the nutrients they take in to produce tissues and perform metabolic functions. Any extra nutrients that the plant does not immediately require can either be retained in the tissues of the plant or discharged back into the soil. Chemical processes including oxidation, reduction, and complexation can impact the availability of nutrients to plants in soil.

For instance, certain nutrients could bind to soil constituents and become less accessible to plants. The availability of nutrients in the soil can also be impacted by biological activity. Bacteria and fungus in the soil have the ability to decompose organic matter and release nutrients for plant uptake.

binomial naming system

The binomial naming system is the system used to name species. Each species is given a name that consists of two parts. The first part is the Genus to which the species belongs and the second part is the species name. For example, Apis mellifera (the honey bee).

In anatomy, the term "distal" refers to a position or location that is farther away from the center of the body or point of reference. It is the opposite of the term "proximal", which refers to a position or location that is closer to the center of the body or point of reference.

For example, in the human arm, the shoulder joint is proximal to the elbow joint, while the wrist joint is distal to the elbow joint. Similarly, in the human leg, the hip joint is proximal to the knee joint, while the ankle joint is distal to the knee joint.

The terms "distal" and "proximal" are also used in reference to structures within organs or tissues. For instance, in the kidney, the distal convoluted tubule (DCT) is the part of the nephron that is farthest from the glomerulus, while the proximal convoluted tubule (PCT) is the part of the nephron that is closest to the glomerulus.

Overall, the terms "distal" and "proximal" are important concepts in anatomy that help to describe the position, location, and relationship of structures within the body.

Of the options listed, the feature of viruses that is most similar to a feature of living things is that viruses have a way to reproduce new viruses.

While viruses are not considered to be alive, as they lack the ability to carry out metabolic processes or replicate independently, they do have a mechanism for creating new viral particles.

When a virus infects a host cell, it hijacks the cellular machinery to produce copies of its own genetic material and proteins. These components are then assembled into new viral particles, which are released from the host cell and can go on to infect other cells. This process is analogous to the replication and reproduction seen in living organisms, which involves the creation of new individuals from pre-existing genetic material.

In contrast, the other options listed describe features of viruses that are distinct from those found in living organisms. For example, while viruses may require host cells in order to be active, they do not themselves grow or develop, as they lack the internal structures necessary for these processes. Similarly, viruses have a basic structure that is not based on cells, as they are composed of a small amount of genetic material surrounded by a protein shell, rather than the complex cellular structures seen in living organisms.

The correct option is C; Through the opening and closing of stomata , located on the leaves' surfaces, are involved in regulating gas interchange and water release. Plants regulate water by opening and closing stomata.

Stomata are small pores placed in the leafs' surfaces, whose opening is regulated by two guard cells surrounding them.

These pores are involved in gas interchange -letting CO₂ get into the plant, and O₂ leave it- and the transpiration process -expelling water through transpiration-.

Guard cells can expand or contract according to the plants' needs, causing the stomata to open or close.

Stomata opening and closure depend on water and CO₂ concentration inside the plant.

·        If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.

·        If CO₂ levels are too low, stomata open to gain it.

So, stomata affect photosynthesis by controlling gas interchange -CO₂ and O₂- and water release -transpiration-.

Water balance:

·        Stomata also regulate water vapor flow through transpiration.

·        By limiting its exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.

According to this information, plants regulate water in their bodies by opening and closing stomata.

Explanation:

Single bonds on fatty acid tails indicate a saturated fat.

The saturated fat theory is a widely discussed concept in the field of nutrition, which proposes that a diet high in saturated fats can contribute to the development of heart disease and other health problems.

The theory is based on the idea that saturated fats, which are primarily found in animal products such as meat, butter, and cheese, can raise levels of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is often referred to as "bad" cholesterol because it is associated with an increased risk of heart disease.

Proponents of the saturated fat theory argue that people should limit their intake of saturated fats and replace them with healthier fats, such as unsaturated fats found in nuts, seeds, and vegetable oils. However, in recent years, the theory has been challenged by some researchers who question the evidence behind it and propose that other factors, such as excess sugar and refined carbohydrates in the diet, may be more important contributors to heart disease.
