Answer:

Its C. W and Z

Explanation:

I just took the test

The combination of atoms will form a molecule, but not a compound are W and Z. Therefore, option C is correct.

The term compound is defined as when two or more substance or element are joined together. Compound is a mixture of two different element. Compounds are formed by two or more than two element combined by chemically in same ratio.

Molecules are formed by two or more than two atom are combined. When same elements combined to formed molecule.

The combination of same atom is called as molecule whereas combination of two different atoms are called as compound.

Two same element formed molecule while two different element formed compound. The oxygen molecule contains two atoms of the same element i.e., oxygen. Therefore, oxygen is a molecule but not a compound.

Thus, option C is correct.

The statistics indicate that RNA Pol will elute first, followed by Ig G, Albumin, RNaseA, and then Cytochrome C therefore, option c is the right choice.

Proteins are distinguished from one another and eluted using gel filtration chromatography on the basis of the size difference between them. Proteins with a higher molecular weight will elute more quickly than proteins with a lower molecular weight.

Gel permeation chromatography, often known as GPC, classifies molecules according to their respective sizes. When sample mixes are run down a column that is filled with material of particular pore size, the components of the mixture are separated into their individual compounds. Larger molecules that are unable to penetrate the pore size of the packed substance (often referred to as a gel) elute faster than their smaller counterparts.

Vigorous, upward lifting leads to large cloud formations associated with storm systems and consequent severe weather

Large cloud formations connected to storm systems may emerge as a result of vigorous, upward air lifting. Water vapour in the air can condense into water droplets and create clouds when moist air rises and cools. Towering cumulonimbus clouds, which are linked to thunderstorms, torrential downpours, and other severe weather events, can form when lifting is strong and persistent enough.

Fronts, which are the borders of air masses with various characteristics of temperature and humidity, can occasionally cause air to be lifted. Warmer air is quickly lifted as a cold front pushes into a warm air mass, which causes storm development. Similarly, the formation of thunderstorms may result from warm air rising along a dryline—the border between humid and dry air.

Cellular respiration is the breakdown of glucose and other molecules by cells to generate energy in the form of ATP. (adenosine triphosphate).

There are three steps to the process: glycolysis, the Krebs cycle, and oxidative phosphorylation.

Cellular respiration has the following molecular equation:

\(C_6H_{12}O_6 + 6O_2 - > 6CO_2 + 6H_2O + ATP\)

This equation represents the breakdown of glucose and oxygen to produce carbon dioxide, water, and ATP.

In contrast, photosynthesis is the process by which plants, algae, and some bacteria transform solar light energy into chemical energy in the form of glucose and other organic compounds.

The process is divided into two stages: light-dependent reactions and light-independent reactions. (also known as the Calvin cycle).

Although cellular metabolism and photosynthesis are diametrically opposed processes, they are also mutually beneficial. The reactants of one process are the results of the other.

For example, the oxygen created during photosynthesis is used by cells to produce ATP during cellular respiration, and the carbon dioxide produced during cellular respiration is used by plants to produce glucose during photosynthesis.

When lung volume increases, the intrapulmonary pressure decreases. This is due to the fact that the lungs are enclosed in the thoracic cavity

which is bounded by the diaphragm at the bottom and the ribcage on the sides. The diaphragm is the primary muscle of respiration, and when it contracts, it flattens and moves downward, increasing the volume of the thoracic cavity. This increase in volume causes the lungs to expand and pull away from the thoracic wall, resulting in a decrease in intrapulmonary pressure.

This decrease in pressure creates a pressure gradient between the atmosphere and the alveoli of the lungs, causing air to flow into the lungs. This process is known as inhalation, and it is the first step in the process of respiration. When lung volume decreases, the reverse happens, with an increase in intrapulmonary pressure causing air to flow out of the lungs during exhalation.

Explanation:

In prokaryotes, the type of RNA that can and cannot be used are dependent on the function it serves.In prokaryotes, three types of RNA can be used whereas RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes.

Prokaryotes are unicellular organisms that do not have a nucleus or membrane-bound organelles. The genetic material is present in the cytoplasm and is arranged in a single, circular DNA molecule. As a result, the RNA transcription and translation occurs in the same location. As a result, there is no alternative splicing or post-transcriptional modification.

Hence, all RNAs are synthesized from a single, uninterrupted gene.In prokaryotes, three types of RNA can be used: Messenger RNA (mRNA) transcribes the genetic information from DNA, which is then translated into a protein. Ribosomal RNA (rRNA) is a major component of ribosomes and is essential for protein synthesis. Transfer RNA (tRNA) is a specialized RNA molecule that carries amino acids to the ribosome during translation. In prokaryotes, RNA that undergoes splicing, such as hnRNA or pre-mRNA, is not used.Eukaryotes are multicellular organisms that have a nucleus and membrane-bound organelles.

Eukaryotic cells have linear DNA arranged into chromosomes and are located in the nucleus. RNA transcription occurs in the nucleus, while translation occurs in the cytoplasm. Eukaryotes also have alternative splicing and post-transcriptional modification. So,RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes. Eukaryotes have five types of RNA that can be used: Messenger RNA (mRNA), Ribosomal RNA (rRNA), Transfer RNA (tRNA), Small nuclear RNA (snRNA), and Small nucleolar RNA (snoRNA). RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes.

Lighter colored mice were more likely to avoid predators and to reproduce. Therefore, option (D) is correct.

The lighter brown coloration of the deer mice in the Sand Hills of Nebraska is likely an adaptation that provides them with a survival advantage in their specific habitat. The light, sandy soil in the area may offer better camouflage for lighter colored mice, making them less visible to predators and increasing their chances of survival.

As a result, these mice would have a higher likelihood of successfully reproducing and passing on their lighter coloration traits to future generations.

Supporting nerve regeneration

Schwann cells are specialized cells that are found in the peripheral nervous system. Their main functions are:

Providing insulation: Schwann cells are responsible for producing a fatty substance called myelin, which surrounds and insulates nerve fibers. This insulation helps to increase the speed of nerve signal transmission and prevents electrical signals from leaking out of the nerve fibers.

Supporting nerve regeneration: When nerve fibers are damaged, Schwann cells play a critical role in facilitating their regeneration. Schwann cells produce growth factors and other molecules that promote the growth of new nerve fibers and help to guide them to their correct destinations. Additionally, Schwann cells can also form a type of scaffold that guides regenerating nerve fibers and provides them with a supportive environment to grow.
