Which two structures are part of the cortisol pathway?

Answers

Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.

The structures that are part of the cortisol pathway are the hypothalamus and liver.

Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.

What structures are in the Cortisol pathway?

The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.

The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.

The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.

Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.

A widow's peak hairline (W) is dominant to straight hairline (w). Cross a heterozygous widow's
peak hairline person with a straight hairline person. What are the genotypic and phenotypic
ratios of their offspring

Answers

Answer:

Use a punnett square! I'll attach an example.

Genotype - Genetic constitution of dominant and recessive traits inherited from parents. BB, Bb, & bb can be used to represent these.

Phenotype - Observable. If a dominant trait is present, it shows as the phenotype. For example, brown hair is dominant to blonde hair. A person with a BB or Bb genotype will have brown hair, but a person with a bb genotype will have blonde hair.

Statistically, they have a 50% chance of a child with a widow's peak, and a 50% chance of a child with a straight hairline.

The genotypic and phenotypic ratios of their offspring are 50% and 50% ratio of the child.

What are the heterozygous ?

The heterozygous are the condition where you have inherited different forms of a particular gene from each  of your biological parents. By different shapes we generally mean that there are different parts of the gene where the sequence is different.

Genotype - Genetic charter of dominant and recessive developments inherited from parents. BB, Bb, & bb may be used to symbolize these.Phenotype - Observable. If a dominant trait is present, it indicates because the phenotype. For example, brown hair is dominant to blonde hair. A individual with a BB or Bb genotype may have brown hair, however someone with a bb genotype may have blonde hair.Statistically, they've a 50% risk of a toddler with a widow's peak, and a 50% risk of a toddler with a instantly hairline.

Explanation:

The cell membrane is not made up of chromatin. Chromatin is found in DNA.The cell membrane obviously does not produce energy for the cell. It acts as a barrier that lets things in and keeps things out. Lastly, the cell membrane is not a rigid layer of cellulose. Cellulose is a component of a cell wall.

natural selectiongenetic variationenvironmental fitnessgene mutations

Answer:

genetic variation

Explanation:

Whenever migration occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.

Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.

For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.

The bigger the difference in allelic frequencies between populations is, the bigger is the effect of the genetic flow.

2. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Which cellular organelle was most likely on the filter paper, and what process was it performing?

Answers

Answer:

Mitochondria; cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

Which of the possible examples below would most likely lead to a change in the cell theory? A Scientists find life on Mars that is not made of cells.

D Scientists gather life from a volcano that is composed of cells which are very different from humans.

Answers

Answer: Probably B?

Explanation:

The possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.

What is the significance of the cell and its importance?

Cell theory explains that life is made up of cells, but If scientists were to discover life on Mars that did not fit this definition, it would challenge the current understanding of the cell theory and the discovery of life on Mars that is not composed of cells would indicate that the cell theory is not universally applicable.

Hence, the possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.
