In a reproductive cell of a fish that was later fertilized to become an organism and the mutation occurred in a gene that coded for a pigment that normally appears blue and as a result of the mutation appears red, it would likely impact the appearance of the organism.

Specifically, the fish would no longer produce the blue pigment and instead would produce a red pigment. This could potentially impact the survival of the fish in its environment, as it may make it more visible to predators or less able to camouflage itself.

Additionally, if the blue pigment had a specific function, such as helping the fish to attract mates or communicate with other fish, the mutation could impact these behaviors as well. However, it's also possible that the mutation may not have any significant impact on the organism's survival or behavior, particularly if the pigment in question is not critical for these functions.

Ultimately, the impact of the mutation on the organism would depend on a variety of factors, including the specific gene that was mutated, the role of the pigment in the fish's ecology and behavior, and the broader environmental context in which the fish lives.

They would all have one cell with smaller parts that do different jobs within the cell.

The question brings a table with information about the DNA and amino acids sequences for cytochrome c. The question is asking about the organism in the table that is closer to dolphin.

Step 1.

First we must exclude the most genetically distant organisms.

The invertebrates Amoeba and Spoge are the ones that are most distant, having sequences most differents than the other organisms in the table, as well as the dolphin. The first amino acid is the criterion to exclude those organisms.

Step 2.

The Lizard, Earthworm, and Shark also have differences in the amino acid seuence for the citochrome c, being more genetically distant than the other animals in the table.

Step 3.

The mammals are the most similar in DNA and amino acids sequences (cat, kangaroo, and dolphin), but to know which one is closer to dolphins we must analyze in detail the data that the question brings.

Amino acid sequence

Cat - have two different amino acids;

Kangaroo- have two different amino acids.

(both have identical sequences between them)

DNA sequences

Cat- there are differences in nucleotides;

Kangaroo- the sequence is identical, even though the amino acids are not all equals.

Step 4.

With the information of the question and the data analyzed, we can conclude that the Kangaroo is the genetically closer to the dolphins between the organisms used as examples for the question.

Explanation:

As every single living organism, the mice also have their own unique requirements as to how much food they need to produce enough energy in order to stay healthy. Because the mice are small, warm-blooded, highly active, and have very fast metabolisms, they need a lot of food for their size.

If one mouse needs four square meters of grass to stay healthy, so if we want to find out how much grass is needed for more mice we just need to multiply the number of mice by the amount of grass needed for one mice. In this case, we have 50 mice:

4 x 50 = 200

We got 200 square meters of grass, meaning that that would be the amount/area of grass that will be enough to support the population of 50 mice.

The stomach of mouse is divided into a glandular (forestomach) and a nonglandular stomach. This region is separated by a ridge around the entrance of the esophagus. The ridge is formed by the thickened lamina propria of the non-glandular stomach. The non-glandular stomach is lined by stratified squamous epithelium, and the glandular stomach is lined by glandular epithelium.

The glandular region contains three types of glands:

The mouse, as well as many other species, has three paired salivary glands - submaxillary (submandibular), parotid, and sublingual (Frith and Townsend, 1985). All three major salivary glands are closely associated and located in the subcutaneous tissue of the ventral neck area.

The submaxillary are the largest and easiest of the salivary glands to identify grossly. They are lobulated, extend posteriorly to the sternum and clavicle, anteriorly to the hyoid bone, and medially to overlap slightly on the median line. Submaxillary salivary glands of male mice are larger and more opaque than those of females.
The much smaller sublingual salivary glands are closely associated with the anterolateral surface of the submaxillary salivary glands.

The parotid salivary glands are lobulated and the most diffuse of the three salivary glands. They extend from the base of the ears, where they overlie the morphologically similar exorbital lacrimal gland, posterior to the clavicle. The parotid salivary glands are classified as serous glands, the sublingual salivary glands as mucous glands and the submaxillary (submandibular) as mixed glands.

The salivary glands secrete saliva which has both a chemical and a mechanical function. The mucous secretion aids in swallowing of food and keeping the mouth moist, and the serous secretion adjusts pH, dilutes food, makes it possible to taste food and hydrolyzes the carbohydrates.

Sickle cell disease is caused by a mutation in the HBB gene, which provides instructions to make beta-globin, a protein component of hemoglobin in red blood cells. Sickle cell disease is an autosomal recessive disorder, which means that an individual must inherit two copies of the mutated gene (one from each parent) to have the disease.

When both parents are carriers of sickle cell disease, there are four possible outcomes for their offspring:

The offspring inherits a normal HBB gene from both parents and is not a carrier of sickle cell disease.

The offspring inherits one normal HBB gene from one parent and one mutated HBB gene from the other parent and becomes a carrier of sickle cell disease.

The offspring inherits one mutated HBB gene from one parent and one normal HBB gene from the other parent and becomes a carrier of sickle cell disease.

The offspring inherits two mutated HBB genes (one from each parent) and has sickle cell disease.

Therefore, the probability of a child inheriting two mutated HBB genes (i.e., having sickle cell disease) when both parents are carriers is 25% (1 in 4).

The electric potential at a point on the axis of the annulus a distance z from its center is given by:  \(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

To exploit the angular symmetry of the problem, we can consider a circular ring of radius r and thickness dr, with charge density λ. The potential dV at a point P on the axis of the ring, at a distance z from the center of the ring, due to a small element of charge dq on the ring is given by:

\(dV = kdq / sqrt(r^2 + z^2)\)

where k is the Coulomb constant.

We can express the charge density λ in terms of the total charge Q on the ring and the circumference C of the ring as:

λ = Q / C = Q / (2πr)

Substituting this expression into the equation for dV and integrating over the entire ring, we get:

\(V = ∫dV = kQ / (2π) ∫dr / sqrt(r^2 + z^2)\)

To evaluate the integral, we can make the substitution \(u = r^2 + z^2, du = 2rdr,\)  to obtain:

\(V = kQ / (4πz) ∫du / sqrt(u) = kQ / (4πz) * 2sqrt(u) = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

Therefore, the electric potential at a point on the axis of the annulus a distance z from its center is given by:

\(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)
