Explanation:

The blood (without oxygen) enters the right atrium of the heart through the inferior and superior vena cavas. From the right atrium, it flows to the right ventricle through the tricuspid valve. Then, the right ventricule squeezes when it's full, closing the tricuspid valve and opening the pulmonary valve. The blood then flows through the pulmonary arteries, entering the lungs, where it gets oxygen. The blood will then leave the lungs through the pulmonary veins, entering the left atrium. From the left atrium it flows through the mitral valve, going to the left ventricle. It leaves the left ventricle and leaves the heart through the aortic valve, flowing in the aorta to reach the rest of the body.

sun rays

Explanation:

biotic factors are ones that are alive which are the tree, tiger, birds, and beetle. abiotic is the ones that are not alive which would be sun rays, air or water. hope this helps

In the image, the sun's rays are the abiotic factor. So the correct option is D.

All the non-living components or factors of an ecosystem are referred to as the Abiotic factors of that ecosystem. They are the chemical factors or the physical factors.

These are present either in the lithosphere, atmosphere, or hydrosphere. Examples of abiotic factors include sunlight, minerals, air, soil precipitation, and everything else that supports life but is not living.

These factors support life in the ecosystem. They help in the survival of the species and their reproduction in the ecosystem.

For example, without the required amount of sunlight, autotrophic photosynthetic organisms would not be able to perform photosynthesis. Thus it will result in their death. Since they are primary producers, the organisms dependent on them, called primary consumers will also die.

This effect will continue to cascade up the food chain and will eventually affect every organism.

Therefore the correct option is D.

Answer:

These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.

Explanation:

Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.

Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.

Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars (by cellulase in certain fungal species), the resulting glucose monomers are properly defined as the products

The correct answer is option E.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars by cellulase in certain fungal species, the resulting glucose monomers are properly defined as the products.

In a chemical reaction, reactants are the starting materials or substances that undergo a change, while products are the resulting substances formed after the reaction. In this case, cellobiose is the substrate, which is the molecule that undergoes the enzymatic reaction. Cellulase is the enzyme responsible for catalyzing the digestion of cellobiose into glucose monomers.

The enzyme cellulase acts as a catalyst in the reaction, facilitating the breakdown of cellobiose into glucose. Catalysts are substances that increase the rate of a chemical reaction without being consumed or permanently changed themselves. However, in the context of the given question, the glucose monomers produced are the final result or product of the enzymatic digestion process.

Therefore, in the digestion of cellobiose, the resulting glucose monomers are correctly identified as the products (option E).

A buffer typically consists of a weak acid plus conjugate base. The buffer system keeps pH constant because if the pH begins to drop to a lower value, the conjugate base acts to absorb \(H^{+}\)ions. Conversely, if the pH begins to rise to a higher value, the weak acid acts to release \(H^{+}\)ions.

A buffer is something like bicarbonate. Bicarbonate can provide a proton when the pH rises too high, turning it into carbonate. The conjugate base, carbonate, can take in a proton and change back into bicarbonate when the pH falls too low.

A buffer is a unique liquid that prevents significant pH level changes. Each buffer that is created has a certain buffer range and buffer capacity. The amount of acid or base that may be added to a buffer before the pH starts to noticeably shift is known as the buffer capacity. It is also possible to define it as the amount of powerful acid or base required to raise the pH of one liter of solution by one pH unit. The buffer range is the pH range where an additional acid or base can be successfully neutralized while a buffer maintains a reasonably constant pH.

The mutation in the \(OCA_2\)gene that causes blue eyes in humans is an example of a non-lethal mutation. Such mutations have a neutral or insignificant effect on an organism's survival and do not significantly impact its ability to reproduce and pass on the mutation to future generations.

The mutation in the \(OCA_2\) gene that leads to blue eyes in humans is an example of a non-lethal mutation. This specific mutation affects the production of melanin, the pigment responsible for the coloration of the iris. Individuals with this mutation have reduced melanin production, resulting in lighter eye color.

Mutations can be categorized based on their effects on an organism. Lethal mutations cause severe impairments that prevent the organism from surviving. These mutations are typically incompatible with life and often result in spontaneous abortion, stillbirth, or early death after birth. Examples of lethal mutations include those affecting vital organs or crucial developmental processes.

In contrast, non-lethal mutations have a neutral or insignificant effect on an organism's survival. These mutations may result in variations in physical traits, such as eye color, hair color, or height, but do not significantly impact the organism's ability to survive and reproduce. Non-lethal mutations often do not confer a selective advantage or disadvantage, and their occurrence is driven by genetic variation and chance.

The mutation in the \(OCA_2\) gene that causes blue eyes is considered a non-lethal mutation because it does not adversely affect an individual's ability to survive and reproduce. While eye color may vary, it does not impact overall fitness or reproductive success. Therefore, individuals with blue eyes can thrive and pass on the mutation to future generations without any significant hindrance.

It is important to note that the categorization of mutations as lethal or non-lethal can vary depending on the specific context and species. Mutations that are non-lethal in one species may have different effects in another. Additionally, the impact of a mutation on an organism's survival and reproductive success can be influenced by environmental factors and genetic interactions.

In summary, the mutation in the \(OCA_2\) gene that leads to blue eyes in humans is an example of a non-lethal mutation. Such mutations have a neutral or insignificant effect on an organism's survival and do not significantly impact its ability to reproduce and pass on the mutation to future generations.
