Answer: I want to say 1 but I think that it is 4

Explanation:

The mouse population would likely decrease if there were a decrease in the amount of sunlight. The correct option is 4.

All the food networks in a single ecosystem make up a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the ecosystem.

A food web is a comprehensive account of the species that make up a community and their interactions with one another. It demonstrates how energy is moved along food chains that are connected to other food chains.

The mouse population here depends on the grass, if there were no grass, there will be a decrease in the mouse population.

Therefore, the correct option is 4, a decrease in the amount of sunlight.

Explanation:

The biological level of seal is higher than fish. The amount of microplastics in the body of fish is X mol. As a seal eats Y fishes one day, so the amount of microplastics in the body of the seal is YX mol.

Seals are the consumers that feed on the fish for food. The concentration of the microplastics in a seal’s body will be higher than the fishes due to a process called bioaccumulation or biomagnification.

Bioaccumulation is the chemical accumulation in higher concentrations in an organism over a period of time where the rate of excretion is slower than the intake.

Biomagnification, on the other hand, is the process where the concentration of the chemicals in the organism at the higher level of the pyramid is more than at lower levels.

The seal is at a higher ecological level in the food pyramid and feeds on fish. The concentration of the microplastics increases in their body as they feed on more fish and are at a higher trophic level.

Therefore, the concentration of microplastics increases in Seals due to bioaccumulation and biomagnification.

Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.

The cross's outcomes make it abundantly clear that black fur is dominant over white fur and that both parents were heterozygous for it.

What are traits that are dominant and recessive?

Characteristics known as dominant traits are those that permeate every generation's progeny.

Characters with recessive traits only show up when the dominant trait is absent.

A cross between a black fur color rabbit and a white fur color rabbit was made in the project, and the offspring all had black fur color.

According to the findings, 25% of the offspring had white fur while 75% had black fur.

Thus, it can be deduced that black fur is dominant over white fur and that both parents were heterozygous for the color.

Answer:

When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.

Explanation:

Have a great day, and spread some positivity!

A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.

The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.

The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.

Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.

If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

The organism has different types of Connective tissues providing support and connectin to organs and other structures. 1) Connective tissue. 2) Dense irregular connective tissue.

The connective tissue, also known as support tissue, supports and connects all the other tissues and organs in the body. Every substance exchange between epitheliums, muscles, nerves, and the vascular system must be done with the connective tissue as an intermediate.

According to its specialization, there are different kinds of connective tissue, such as cartilage, blood, bony tissue, or lymphatic tissue, among others. Each type of connective tissue has its own cell type according to its functions. Cellular types, fibers, and aqueous medium appear in different amounts in different parts of the organism.

The connective tissue is composed of cells that are very separated from each other because of the abundant extracellular matrix, which is produced by fibroblasts, a predominant cell population. The extracellular matrix has fibrillar proteins of different natures such as collagen, fibrillin, and elastin that determine tension properties.  There are also adessive proteins such as fibronectin and laminin. All of these proteins are included in a medium that contains water, salts, GAGs, proteoglycans, glycoproteins, and other macromolecules that confer turgidity and facilitate diffusion. The properties of this matrix in different connective tissues mark the difference between each other.

The connective tissue originates in the mesoderm, which in the early stages of development, differentiates from an embryonary connective tissue called mesenchyme.

Behavioral adaptations include birds migrating and laying in the sun to warm up body temperatures (Options 6 and 5); structural adaptations include flippers to swim, camouflage, and large ears to radiate heat (Options 2, 4 and 3); physiological adaptations include toxins in plant leaves, compounds that prevent the coagulating of blood, and bears hibernating (Options 1 and 7 and 8).

Evolutionary biological adaptations are different strategies that organisms have to survive in particular environmental conditions, which may involve behavioral strategies in which the organisms exhibit certain behaviors to fit environmental conditions.

On the other hand, physiological adaptations are based on changes in the biological mechanisms of organisms such as the movement of blood in certain conditions, while structural adaptations are related to changes in the anatomy.

Therefore, with this data, we can see that evolutionary biological adaptations are diverse and they are associated with strategies to survive and reproduce.

Answer:

Genotypic ratio = 1:2:1

Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

Explanation:

This question involves a gene coding for the ability to roll the tongue or not in humans. The allele for tongue rolling (R) is dominant over the allele for non-tongue rolling (r).

According to this question, two individuals that are heterozygous for tongue rolling mate i.e. Rr × Rr. The proportion of offsprings that will be likely produced from this cross will be: RR, Rr, Rr, and rr.

- Offsprings with RR, Rr, Rr are tongue rollers

- Offsprings with 'rr' are non-tongue rollers.

Hence, the predicted genotypic and phenotypic ratio are as follows:

Genotypic ratio = 1 RR :2Rr :1rr

Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller
