Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

Answer: Sympathetic Nervous System.

Explanation:

The sympathetic nervous system is part of the autonomic nervous system. The sympathetic nervous system activates what is often termed the fight or flight response. The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles. Breathing quickens, delivering fresh oxygen to the brain, and an infusion of glucose is shot into the bloodstream for a quick energy boost. The sympathetic nervous system allows animals to make quick internal adjustments and react without having to think about it.

Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished
Amanda [17]

Answer:

Stabilizing selection

Explanation:

The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.

During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.

In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages.  Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.

Thus, Stabilizing selection is correct.

Male-pattern baldness is a X-linked recessive trait, labelled X^{\text{b}}
VashaNatasha [74]

Answer:

100%

Explanation:

Pattern baldness if X linked and recessive.

A father with X^BY and a mother with X^bX^b have a son.

First, let us look at the result of the cross between the two:

X^BY   x   X^bX^b

male progeny: X^bY, X^bY

female progeny: X^BX^b, X^BX^b

<em>The two sons resulting from the cross inherited male pattern baldness. Hence, the percentage chance that the son will inherit male pattern baldness is 100.</em>

The filtrate formed by the nephrons in the kidney is NOT urine. The filtrate is first refined and concentrated by the processes
dexar [7]

The filtrate is first refined and concentrated by the processes of <u>reabsorption and secretion</u>, which form the urine that leaves the body.

<h3>Process of filtration in kidney:</h3>

The glomerulus filters your blood, and the tubule restores necessary substances to your blood while removing waste. The glomerulus is nestled within a region of the kidney called the Bowman's Capsule. This is where filtration occurs. The high pressure causes some substances to pass through the capillary walls when blood is forced through the tiny capillaries. The walls serve as a filter or sieve. This is how the function of the nephron. A glomerulus filters your blood, while a tubule restores necessary substances to your circulation while removing extra waste. Each nephron has both of these functions.
