Stimulation of glucose production and release into circulation to provide a quick fuel source for muscle tissue so that the body is readied for action during a stress event.

Option B.

<h3><u>Explanation:</u></h3>

Cortisol is a steroid group of hormone that is secreted from the Adrenal Cortex from the zona fasciculata. It's the middle layer of Adrenal Cortex. Cortisol helps in different functions of the body that includes the suppression of immune system, increasing the blood sugar level,  gluconeogenesis, metabolism of fat, and proteins. This hormone helps in the gluconeogenesis which helps to produce glucose from non glucose sources. The primary sources include the fats and proteins and the glycogen reserve in liver and muscles. Thus increase in cortisol levels help in the retaining glucose levels in stress or hypoglycemia.

Inessa05 [86]
The nurse can inform the girl's mother that menstruation is likely to occur in about 2 to 2 ½ years. Breast development begins about 8 to 13 years of age; but generally this begins around age 9 or 10, but can typically happen earlier or later. This is called “breast budding.”  Menstruation occurs about 2 to 2 ½ years after breast development.

Some of the things observed when a human red blood cell is placed under a microscope are:

  • They have a donut shape
  • They look like biconcave discs
  • The presence and/or absence of a nucleus

<h3>What is a Microscope?</h3>

This refers to the lab tool that is used to view very small objects in detail to find out their properties.

Hence, we can see that although your question is incomplete, a general idea of things that can be observed when a human red blood cell is placed under a microscope was discussed.

The electrophoretic run or EMSA change test for its initials in English (electrophoretic mobility shift assay) is a technique used to investigate interactions between proteins and DNA or RNA. The technique is based on an electrophoretic run between labeled DNA or RNA fragments and the presence of cell extracts. The basic DNA assay consists of a lane only with the DNA fragment of labeled interest, a second lane with the same DNA plus proteins that, under the given conditions, do not interact with it, and the third lane containing the same fragment of DNA plus proteins with supposed interaction with that sequence. Depending on the result of the third lane, it can be determined whether or not there was interaction. A DNA fragment interacting with proteins tends to travel less distance through the gel at the same time as in lanes 1 or 2, and therefore should be delayed. This technique is based on the works of Garner and Revzin and Fried and Crothers

Due to their physicochemical properties, proteins can be classified into simple proteins (holoproteids), formed only by amino acids or their derivatives; conjugated proteins (heteroproteides), formed by amino acids accompanied by diverse substances, and derived proteins, substances formed by denaturation and unfolding of the above. They consist of structural units called polymers4. Proteins are necessary for life, especially for their plastic function (they constitute 80% of the dehydrated protoplasm of every cell), but also for their bioregulatory functions (they are part of the enzymes) and defense (antibodies are proteins). 5

Proteins play a fundamental role for life. They represent about 50% of the dry weight of the tissues.6 They are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge number of different functions, among which are:

Structural. This is the most important function of a protein (eg, collagen)

Contractile (actin and myosin)

Enzyme (Ex .: sucrose and pepsin)

Homeostatic: collaborate in maintaining pH (since they act as a chemical buffer)

Immunological (antibodies)

Scab production (eg, fibrin)

Protective or defensive (Ex .: thrombin and fibrinogen)

Signal transduction (eg, rhodopsin).

Proteins are composed of amino acids. The proteins of all living beings are mostly determined by their genetics (with the exception of some antimicrobial peptides of non-ribosomal synthesis), that is, genetic information largely determines what proteins a cell, a tissue and an organism have.

Proteins are synthesized depending on how the genes that encode them are regulated. Therefore, they are susceptible to external signals or factors. The set of proteins expressed in a given circumstance is called a proteome.

Through a family of methods called peptide synthesis it is possible to chemically synthesize small proteins. These methods depend on organic synthesis techniques such as ligation to produce peptides in large quantities.10 Chemical synthesis allows the introduction of unnatural amino acids into the polypeptide chain, such as amino acids with fluorescent probes linked to their side chains.11 Methods are useful in laboratories of biochemistry and cell biology, but not so much for commercial applications. Chemical synthesis is inefficient for polypeptides of more than 300 amino acids, and synthesized proteins may not readily adopt their native three-dimensional structure. Most chemical synthesis methods come from the C-terminal end to the N-terminal end, in the opposite direction to the biological reaction.
