The shared derived character that can be written  at pint x ill be multicellular and eukaryotes.

Eukaryota, whose members are known as eukaryotes, is described as  a diverse domain of organisms whose cells have a nucleus.

We know that shared or derived characteristics or synapomorphies are the characters which were evolved in the ancestors of special groups of organisms and after that they were transferred to the descendants (or lineages) of those groups as well.

These characteristics play a crucial role in the group of organisms. As we move closer to the question, we notice a hybrid of the plant and fungus kingdoms.

Answer:

A.

Explanation:

Metabolic rate refers to the rate at which an animal burns calories to produce energy. Among vertebrate species, \(10^{7}\) fold of the range of metabolic rate are present.

Even among vertebrate species of the same weight and higher taxon, there are large differences in metabolic rate, with various explanatory factors postulated such as energy content, latitude, altitude, temperature and precipitation. A consistent underlying factor may be the availability of food, which is controlled by the net primary productivity (NPP) of the animal's natural environment.

To test this possibility, we examined five of his Peromyscus mice in North America. All of these have similar diets (common omnivores) and gut morphology, but differ up to 13-fold in his NPP in native habitats. We maintained breeding colonies of all five species in the laboratory under identical conditions and on identical diets. Basal metabolic rate (BMR) and daily uninterrupted food intake were both increased with NPP, accounting for 88% and 90% of the difference, respectively.

Answer:

When creating proteins from mRNA templates .

Explanation:

The nucleotide sequence on the RNA is translated into amino acid sequence of proteins. This is carried out by ribosomes.

When individuals with a particular phenotype have higher fitness when they are rare, this phenomenon is known as positive frequency-dependent selection.

In positive frequency-dependent selection, the fitness of a phenotype increases as it becomes less common in the population. This type of selection can arise due to various reasons. One possibility is that the phenotype provides an advantage in specific situations or environments where it is less likely to encounter competition or predation. In such cases, individuals with the rare phenotype have a higher chance of survival and reproductive success, leading to an increase in their fitness.

Positive frequency-dependent selection can also result from social interactions or cooperative behaviors. For example, in certain species, the success of a behavior or trait may depend on the presence or cooperation of other individuals with the same phenotype. In these cases, individuals with the rare phenotype may have an advantage in accessing resources or gaining cooperation, leading to increased fitness.

Overall, positive frequency-dependent selection promotes the maintenance of genetic diversity in populations by favoring rare phenotypes, which can contribute to the stability and adaptability of species in changing environments.

Explanation:

An isotonic solution is:

O A solution that has the same osmotic pressure as a cell.

An isotonic solution refers to a solution that has the same osmotic pressure as the cell it is compared to.

Osmotic pressure is the force exerted by the solutes in a solution that drives the movement of water across a semipermeable membrane, such as the cell membrane.

In the case of an isotonic solution, the concentration of solutes outside the cell is balanced with the concentration of solutes inside the cell. As a result, there is no net movement of water into or out of the cell. The fluid environment outside the cell is in equilibrium with the cell's cytoplasm.

When a cell is placed in an isotonic solution, the movement of water across the cell membrane is equal in both directions. Water molecules enter and leave the cell at an equal rate, maintaining the cell's size and shape. The osmotic pressure inside the cell is balanced with the osmotic pressure outside the cell.

Isotonic solutions are commonly used in medical settings, such as intravenous (IV) fluids, to maintain fluid balance and prevent cells from shrinking or swelling due to osmotic imbalances. Examples of isotonic solutions used in medicine include normal saline (0.9% sodium chloride) and Lactated Ringer's solution.

The cecum is actually located at the beginning of the large intestine or colon, at the point where the small intestine (ileum) connects to the large intestine. The descending colon is located lower in the abdomen, on the left side, and extends from the splenic flexure to the sigmoid colon.

The cecum is a pouch-like structure that is considered to be the beginning of the large intestine. It is located in the lower right quadrant of the abdomen, in the region known as the right iliac fossa. The ileum, which is the final part of the small intestine, connects to the cecum at a point called the ileocecal valve.

The descending colon, on the other hand, is located in the left lower quadrant of the abdomen. It extends from the splenic flexure (located near the spleen) to the sigmoid colon, which is the S-shaped portion of the colon that connects to the rectum. The descending colon is part of the large intestine, and it is responsible for absorbing water and electrolytes from the fecal matter that passes through it.

Therefore, the cecum and the descending colon are two separate structures located at different parts of the abdomen, and they are not connected to each other.

Explanation:

After fertilization occurs, a sporophyte will be produced via meiosis. This process is an essential part of plant reproduction, which is commonly used in greenhouses, gardens, and plant nurseries.

Meiosis is a type of cell division that produces four daughter cells that are genetically distinct from each other. This process plays an essential role in the reproduction of sexual cells or gametes. It occurs in plants and animals that reproduce sexually. Meiosis has two stages, Meiosis I and Meiosis II.In Meiosis I, homologous chromosomes combine to form a structure called a tetrad. The tetrads exchange genetic material during a process called crossing-over, which leads to the exchange of genetic information.

After crossing-over, the chromosomes separate, forming two daughter cells.In Meiosis II, the chromosomes separate, forming four genetically distinct daughter cells. In plant reproduction, this process is used to create a sporophyte, which is the dominant generation of the plant life cycle. The sporophyte produces spores via meiosis, which eventually grow into gametophytes. The gametophytes produce gametes, which can then fertilize other gametes to produce a new sporophyte.
