Answer: Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.

Explanation:

Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.

Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.

Moreover, evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Hence, evolutionary processes depend on both changes in genetic variability and changes in allele frequencies over time.

The statement that "the skin is not able to receive stimuli because the cells of the epidermis are not living and therefore there are no sensory receptors in the skin" is not entirely correct, so the answer is false.

While it is true that the cells of the epidermis, particularly the outermost layer called the stratum corneum, are composed of dead cells that are no longer living, the skin is still able to receive stimuli through the presence of sensory receptors.Sensory receptors are specialized cells that are responsible for receiving and transmitting stimuli from the environment to the central nervous system. In the skin, there are different types of sensory receptors that respond to different stimuli, such as pressure, temperature, pain, and touch. These sensory receptors are located in the dermis layer of the skin, which lies beneath the epidermis.

Keratinocytes, on the other hand, are the most abundant cell type in the epidermis and are able to synthesize the protein keratin, which provides structural support and helps to make the skin waterproof. They are found throughout all epidermal strata, and while they are primarily composed of dead cells, they can also be alive in some areas where they are actively dividing and differentiating into new skin cells.

A look under the microscope will show the cells rapidly shrink and crenate.

Tonicity can be defined as the ability of an extracellular solution to make water move out or move into of a cell through the process of osmosis.

If a blood sample is placed in an isotonic saline solution and viewed under a microscope, the blood cell will be seen as shrinking and crenate as water molecules move by osmosis from a higher concentration to a lower concentration.

The tonicity of a solution often directly correlates with the osmolarity of the solution.

In conclusion, in a hypertonic solution the extracellular fluid has a higher osmolarity than the blood cells meaning that the fluid contains less water than the cell does.

The fluctuation test performed by Luria and Delbruck is consistent with the random mutation hypothesis. Here is a brief outline of their experiment, ranked from the first to the last step:

1. Luria and Delbruck took a large culture of a bacterial strain susceptible to infection by a bacteriophage.
2. They split the culture into smaller cultures.
3. They allowed the cultures to double for multiple generations.
4. They plated samples containing equal numbers of bacteria from the cultures on Petri plates containing the bacteriophage.
5. They determined how many colonies grew on each plate.

By analyzing the results of their experiment, Luria and Delbruck were able to show that the number of bacterial colonies on the plates varied greatly, even when the starting cultures were identical. This variation is consistent with the random mutation hypothesis, which suggests that mutations occur randomly in bacteria and that these mutations can confer resistance to bacteriophages. Therefore, their experiment supports the idea that mutations play a key role in the evolution of bacterial populations.

Answer:

pancreas

Explanation:

the pancreas is what releases insulin in the body

Pancreas' beta cells produce insulin in response to the blood's growing glucose levels. When blood glucose levels increase, the pancreas begins to secrete insulin.

Glucose from the blood can be absorbed by the cells in the muscles, fat, and liver because of insulin.

These cells use the glucose as fuel, or they can turn it into fat when they need it. Other metabolic processes, such the breakdown of fat or protein, are also impacted by insulin.

Glucose, a form of sugar, is lowered in the blood by the hormone insulin. When the blood glucose level rises, such as after eating, it is produced by the pancreatic beta cells and released into the blood.

Glucose can either be saved for later use or utilized as fuel in the body's cells with the assistance of insulin.

Therefore, Pancreas was producing too much insulin, causing low blood sugar. Pituitary gland adrenal gland gonads thyroid gland.
