Answer:

Evolving.

Explanation:

The Hardy-Weinberg equilibrium emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a given population, gene frequencies and genotypic proportions will remain constant. This means that if there are, for example, alleles B and b in a population, they do not change their rates over a long period of time. These rates would only change if evolutionary mechanisms occurred.

For this reason, we can say that "evolving" is the term that can be applied to a population that is not in Hardy-Weinberg equilibrium.

Answer:

B. differential reproductive success caused by genetic variation is necessary for the process of natural selection.

Explanation:

Natural selection is the process wherein individuals with adaptive genetic variations are favored. Genetic variations are present among the individuals of a population. Individuals with adaptive genetic variations survive more and reproduce to leave more progeny. Their progeny also carries the selected adaptive genetic variations.

Over the generations, the population evolves into a population with more number of individuals carrying those beneficial genetic variations.

Since natural selection favors the individuals with the genetic traits that make them better adapted to prevailing surroundings, it leads to the evolution of populations.  

The isomers of butene with methyl groups on the same side and on opposite sides of the double bond are called geometric isomers, specifically cis-2-butene and trans-2-butene.

The isomers described are examples of geometric isomerism, which is a type of stereoisomerism. The cis isomer has both methyl groups on the same side of the double bond, whereas the trans isomer has the methyl groups on opposite sides. The restriction on rotation around the double bond creates two distinct molecules, cis-2-butene and trans-2-butene, which differ in physical properties such as boiling point due to the different placements of the methyl groups.

An alcoholic would have overactive alcohol dehydrogenase system in their liver cells. The alcohol dehydrogenase system metabolizes ethanol in the liver by converting it into acetaldehyde.

An alcoholic would have overactive alcohol dehydrogenase system in their liver cells. The liver metabolizes alcohol using two main processes, the alcohol dehydrogenase system and the microsomal ethanol oxidizing system (MEOS). About 80 to 90% of the hepatic ethanol uptake is processed via the alcohol dehydrogenase system, which converts ethanol into acetaldehyde.

Since acetaldehyde is toxic, it must be further degraded by acetaldehyde dehydrogenase into acetate, a non-toxic molecule. Therefore, an alcoholic would have overactive alcohol dehydrogenase enzymes in their liver cells to metabolize the excessive amounts of alcohol.

Electrolytes are the minerals given externally to provide energy. They have a charge to balance the pH and fluid as they are ionized salts that can conduct electricity. Thus, option C is correct.

Electrolytes are fluids that comprise minerals and are in the form of ions that are electrical conductors due to the presence of the charge. They are essential for survival as many metabolic and automatic processes occur and rely on electrolytes.

Many fruits, vegetables, and chemicals like potassium, sodium, and calcium are rich sources of electrolytes. Its balance is vital in the body as it plays a crucial part in pH and osmosis. Its unbalance can lead to dehydration, water retention, weakness, seizures, etc.

It can be treated and given as oral rehydration therapy and electrolyte replacement therapy, where the electrolytes are injected orally or through IV to maintain their balance in the body.

Therefore, the electrolytes are ionized salts.

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).

The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles.

Only a small amount of light penetrates beyond this depth.

The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a miniscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible.

The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness.

The correct term, which is used to describe the water coming from the sky due to the condensation of the water present in the cloud is precipitation.

The precipitation is the water, which comes in form of the rain, hail, snow, drizzle or sleet. This is one of the main sources of the water supply in the biome. The other types of water supply are ground water and the surface water.  

The proteins and carbohydrates are the two of the four biological macromolecules. The proteins and carbohydrates are the polymers made of the monomeric units amino acids and monosaccharides, respectively. When during the process of digestion, these macromolecules are broken up, they lead to the formation of their constituting monomeric units. The breaking down of carbohydrates yield monosaccharides, and the breaking of protein yields amino acids.

Hence, the blanks can be filled with 'monosaccharides and amino acids' respectively.

The cytoskeleton acts as a support structure for cells and helps in organizing cell activities and movement of molecules within the cell.

The cytoskeleton is a network of protein filaments that provides structural support to cells and plays a crucial role in a variety of cellular functions. The main functions of the cytoskeleton include:

However, the cytoskeleton does not have a direct role in providing scaffolding for enzymes in certain areas of the cell or in assembling ribosomes.

Answer:

Only 1/3 of US doctors are specialists and subspecialists.

Explanation:

An expert doctor is one who works with a specific field of medicine (such as an endocrinologist who deals only with hormonal issues, for example). A subspecialist doctor is another doctor who specializes in some organ or, what is often occurring, some specific disease.

This type of professional requires a long time of study and a great economic expense with the academic specialization, therefore, there are fewer specialist doctors and subspecialists than genealogical doctors, as general practitioners, who although they study a lot, can practice the profession in a shorter time period. It is estimated that only 1/3 of doctors in the US are specialists and subspecialists.

Explanation:

Freediving involves diving without scuba gear, and divers must manage pressure and buoyancy without the aid of equipment. Rapid ascent can cause decompression sickness due to the formation of gas bubbles in the blood. Hyperventilation prior to diving can change CO2 concentration in the blood.

Freediving is an activity where a person dives underwater without the use of scuba gear, often holding their breath for extended periods. Factors such as pressure, buoyancy, and gas solubility play significant roles in the diver's experience underwater. When divers descend, pressure increases, causing the body's air pockets in the ears and lungs to compress. During ascent, these air pockets expand due to decreased pressure. Rapid ascents can lead to decompression sickness, also known as the bends, as dissolved gases in the blood become bubbles, causing various medical conditions. Therefore, divers need to ascend slowly or make several decompression stops.

Hyperventilation before diving can change the concentration of CO2 in the blood. However, no matter the methods used to prepare for a dive, challenges such as decompression sickness and the physiological changes brought on by pressure changes are complex and intriguing areas of research in the field of diving biology.
