Answer:

Hardy-Weinberg equilibrium

Explanation:

The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

Answer:

the dissolved oxygen of the water decreases.

the fish need the oxygen for respiration, breathing through their gills.

Explanation:

The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.

more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.

temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.

Answer:

The butterfly population would decrease or die out.

Explanation:

If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Answer:

(A) nitrates—proteins

Note: The question is not complete. The complete question is given below:

Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule

synthesized by plants using that product?

(A) nitrates—proteins

(B) ammonia—carbohydrates

(C) nitrogenous wastes—nitrites

(D) atmospheric nitrogen—nitrates

(E) atmospheric nitrogen—ammonia

Explanation:

The nitrogen cycle refers to the cycle through which nitrogen is transferred for use through both living and non-living things, involving the atmosphere, soil, water, plants, animals and bacteria.

The nitrogen cycle is especially important for living things because nitrogen is essential for the formation of amino acids which form proteins.

The nitrogen cycle occurs in five stages:

1. Nitrogen fixation - Nitrogen gas from the air is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds.

2. Nitrification - Ammonia is converted to nitrates by nitrifying bacteria in the soil.

3. Assimilation - Plants absorb nitrates from the soil and use them to make proteins. The plant is then eaten by an animal and are used to produce animal protein.

4. Ammonification- Decomposers break down the bodies of dead organisms, urine and faeces converting them to ammonia in the soil, which is then converted to nitrates by nitrifying bacteria.

5. Denitrification - Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air.

From the above stages and the options provided, the correct option is A - nitrates from the nitrogen cycle is converted to protein by plants.

Answer:

Water, ions, glucose, fluids

Explanation:

This is because the nephron have network of cappilaries vessel called glomerulus . This glomerulus filter blood in the kidney to make urine. The hydrostatic force cause the filtrate to be filtered out through pressure.

The nephron also posses tubule which help to return needed or essential substances like protein, ions to the blood and then remove waste products from the blood.

Answer:

The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.

What is the phenotype? Purple plants.

What is the genotype for a h0m0zygous dominant for freckles? FF

What is the phenotype? Freckles

What is the genotype for a h0m0zygous recessive for freckles? ff

What is the phenotype? No freckles

What is the genotype for a heterozygous individual for freckles? Ff

What is the phenotype? Freckles.

Each individual has two alleles for a given gene.

For example, the allele dimples are dominant. How would you represent this allele? With capital letters, for example, DD.

The allele for no dimple is recessive. How would you represent this allele? With lowercase letters, for example, dd.

The allele for brown eyes is dominant. How would you represent this allele? With capital letters, for example, BB.

The allele for blue eyes is recessive. How would you represent this allele? With lowercase letters, for example, bb.

PP: h0m0zygous dominant; Yy: heterozygous; Ss: heterozygous; bb:h0m0zygous recessive; FF: h0m0zygous dominant

Explanation:

Every being, such as plants, animals, or humans, have two different copies of a gene. These are alleles. These copies can be dominant or recessive.

Dominant genes are the ones that we will see. They "hide" the recessive gene. Recessive genes are the ones that we will only express if the two alleles are recessive since there is no dominant gene that hides the other.

Genotype is the genes that an individual or animal has. We can not see it. For example, a person can have a dominant trait for blue eyes and a recessive trait for brown eyes (Bb)s. In other words, it is the genetic information that a person carries. The phenotype is what we can see of a trait. Following the previous example, the dominant trait is blue eyes, and the recessive is brown, so the gene that will express itself is blue eyes, and we will able to see it.

The pair of alleles can be h0m0zygous and heterozygous. H0m0zygous is when the two traits are the same, for example, BB or bb. Heterozygous is when the traits are different, like, Bb.

Pea plants have two flower varieties where purple is dominant over white. The dominant trait, we represent it with a capital letter, in this case, P, because it is the first letter in purple. The recessive trait we represent it with a lowercase letter, in this case, p.

The genotype for a h0m0zygous dominant plant would be PP. We have to remember that the genotype is the information that the plant carries. If this information is h0m0zygous, it means the two alleles are the same, and if they are both dominant, we write capital letters. The phenotype is what we can see of the information; the gene that it is expressed, in this case, would be the color purple.

A h0m0zygous recessive plant has two alleles with the same information, and as they are recessive, we write two lowercase letters (pp). The genotype would be white plants since there is no dominant allele that covers the recessive one.

In a heterozygous plant, the traits are different. We have the dominant trait purple (P) and the recessive trait white (p). The dominant is the one that will express itself and the one that we will be able to see, see in a purple plant.

The following questions are similar to the first one. We know that freckles are a dominant trait, so we use a capital letter to represent it (F) and a lowercase letter to portrait the recessive trait, which is no freckles (f).

A h0m0zygous dominant means that the two alleles are the same and that one does not hide the other so, the genotype would be FF, and the phenotype would be a person with freckles.

If the person is h0m0zygous recessive, it means that it has the same traits, but one allele does not hide the other. The genotype would be ff, and the phenotype would be no freckles.

In the last case, the person is heterozygous, which means that it has one dominant and one recessive allele. The dominant allele will express itself; the genotype would be Ff, and the phenotype freckles.

In the following questions, we know that we represent dominant alleles with capital letters and recessive ones with lowercase letters, if it is a dominant allele for brown eyes, we write BB, taking the first letter of the dominant trait, in this case, brown. If it is a recessive trait, we write lowercase letters, in this case, bb for blue eyes.

In the last set of questions, we have to observe the letters to find the genotype.

PP, FF: the two letters are the same, which means that the allele is h0m0zygous. Also, they are both in capital letters, so they are dominant traits. Yy, Ss: the two letters are different, one is in capital letters, and the other is not. The allele is heterozygous. bb: the two letters are the same, so they carry the same information. They are h0m0zygous. Both of them are in lowercase, so they are recessive alleles.
