Answer:

the process by which amino acids are linearly arranged into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes.

Explanation:

A detergent works by solubulizing grease and forming an emulsion of the grease with water.

A detergent is commonly used as a cleaning agent. Every detergent consists of a hydrophobic tail and a hydrophilic head. The hydrophilic head is capable of interaction with water hence the detergent can dissolve in water. Its hydrophobic tail is capable of interaction with grease.

A detergent works by agglomerating its molecules into micelles which dissolve the grease. Mechanic scrubbing completely eliminates the grease creating an emulsion with water.

The tRNA molecule knows to stop translation Stop Codons Mark the End of translation. It reaches a stop codon on the mRNA.

The end of the protein-coding message is motioned by the presence of one of three codons (UAA, UAG, or UGA) called stop codons. These are not accepted by a tRNA and do not state an amino acid, but instead signal to the ribosome to stop translation.

Translation ends in a procedure called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) undertakes the A site.

So we can conclude that No tRNAs in the cell have anticodons that companion any of the three feasible stop codons.

Answer: ADAPTIVE COLORATION

Explanation:

Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.

Adaptive coloration may be grouped into :

--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.

--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.

--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.

Yes, glass lenses would still alter the direction of light rays even if light traveled at the same speed in both glass and air. This is because the refraction of light, or the bending of light as it passes through a medium with a different refractive index, is not solely dependent on the speed of light.

 Glass has a higher refractive index than air, meaning that light will slow down more as it passes through glass than it does through air.  This causes the light to bend or refract when it enters or exits the glass lens.

The degree of bending depends on the shape of the lens and the angle at which the light enters.  Therefore, even if light traveled at the same speed in both glass and air, a glass lens would still alter the direction of light rays.

This is why lenses made of different materials, such as plastic or crystal, are also able to refract light and are commonly used in optics and photography.

After digesting DNA with a restriction enzyme, you would expect more DNA fragments than undigested DNA. These fragments would be smaller than the undigested DNA. The correct option is (C) more and smaller, respectively.

A restriction enzyme cuts DNA by recognizing a specific DNA sequence, then breaking both strands of the DNA at specific points within that sequence. Restriction enzymes are commonly used to cut DNA into small pieces that can be more easily studied in the lab.

The use of restriction enzymes is referred to as a molecular scissors. Restriction enzymes are enzymes that cut DNA molecules into smaller pieces. There are different types of restriction enzymes that cut DNA at different sites; they act as molecular scissors. These enzymes are named after the bacterium from which they are isolated.

They recognize and bind to specific sequences of DNA known as restriction sites, and they cut the DNA at or near these sites. When DNA is digested with a restriction enzyme, the resulting DNA fragments are called restriction fragments.

Therefore, correct option is C.

Candida and Pseudomonas are both opportunistic pathogens, meaning they are not usually pathogenic to healthy persons with normal immune system functions. However, in certain conditions, such as when the immune system is weakened, these microbes can cause disease. Thus, option D is the correct answer.

Pathogens are microorganisms that can cause illness or disease in humans, animals, or plants. These organisms can spread from one host to another and cause infections. Pathogens can be bacteria, viruses, fungi, or parasites.

Pseudomonas is a genus of gram-negative bacteria that are naturally found in soil, water, and plants. They are opportunistic pathogens that may cause a range of diseases in humans, plants, and animals.

Candida is a type of fungus that naturally occurs in the human body. It usually doesn't cause any harm but can cause infections in individuals with a weakened immune system. Candida infections can affect the skin, mouth, throat, or genitals.

Candida and Pseudomonas are not usually pathogenic to healthy persons with normal immune system functions because they do not have well-developed virulence factors, which may include toxins, adhesins, or capsules that help the pathogens evade the host's immune system.

Since Candida and Pseudomonas do not produce these virulence factors, they are not usually pathogenic to healthy individuals. Thus, they are opportunistic pathogens. So, option D is correct.

Vaporized tungsten can act as a filtration medium in certain applications by condensing or coagulating particles from a gas stream onto its surface. This is known as the "diffusion" or "adsorption" method of filtration.

In this method, the gas stream containing the particles to be filtered is passed through a chamber or tube containing vaporized tungsten. As the gas stream flows through the chamber, the tungsten vapor condenses onto the surfaces of the particles, causing them to stick together and form larger particles. These larger particles are then removed from the gas stream through gravitational settling or mechanical filtration.

The effectiveness of this filtration method depends on several factors, including the size, shape, and composition of the particles being filtered, as well as the temperature, pressure, and flow rate of the gas stream. Additionally, the tungsten vapor may also react chemically with certain gases or pollutants in the gas stream, further enhancing its filtration capabilities.

In the absence of natural selection, genetic drift leads to alleles becoming fixed in a limited population during the course of evolution. Allele frequency  and their magnitude are influenced by genetic drift.

Genetic drift, also known as allelic drift or the Wright effect, is a shift in a population's frequency of an existing gene variant (allele) brought on by chance. Genetic drift, may totally vanish due to genetic drift, hence reducing genetic variation.

The frequency of an event is its repetitions per unit of time. As a contrast to spatial frequency, it is also sometimes referred to as temporal frequency, and as a contrast to angular frequency, it is sometimes referred to as ordinary frequency.

Answer:

The different species

Explanation:

There are two types of variable in a scientific experiment; Dependent and Independent variable.

An Independent variable is the variable that is intentionally or expectedly altered in order to see the effect on the dependent variable.

A dependent variable is the variable that is been observed for changes as a result of the independent variable.

For example, in the relationship between age and blood pressure, age is the independent variable while blood pressure is the dependent variable.

From the question, the different human populations is the independent variable (because it is the one been intentionally altered) while the biodiversity/different species is the dependent variable (because it is been observed for changes as a result of the different human population).
