Answer:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction.

As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction. If insulin does not work correctly, it may not be able to bind to the insulin receptor.
DNA contains genetic information. It has a double helix structure.
If the potato slice becomes soft and limp after soaking for one hour in the solution, the solution is hypertonic.
<h3>What is a hypertonic solution?</h3>
In biology, a hypertonic solution is a solution with more solute concentration than it is found in the sap of any other cell placed in it.
Such solutions have lower water potential than the cells placed in them. Thus, water will readily move by osmosis from the sap of the cells into the solution.
Cells that are placed in hypertonic solutions, therefore, usually end up becoming flaccid as a result of water loss.
So, if after soaking for one hour in a solution whose concentration is not known, a slice of potato becomes soft and limp, it means the solution is hypertonic.

Both were powerful nations and they served as trading hubs in their respective regions during that time.
Answer:
A (Genotype)
Explanation:
All organisms possess genetic material which contains information required for certain functions/traits. This genetic material is stored as DNA and contains certain segment that encodes functional products (proteins) called GENE. The make-up of the genes responsible for a particular characteristics in an organism is called the GENOTYPE. Genes occur in variant forms called ALLELES, which are inherited from each parent.
These alleles are responsible for the varying expression of a particular trait e.g. allele T can be responsible for Tallness while the variant form, allele t can be responsible for shortness. In this example, we can see that height is the trait here but the different alleles encode varying expression of it. The combination of the alleles received by both parents, which collectively determines the trait to be expressed is the GENOTYPE.
N.B: The genotype refers to the physically invisible genes not the expressed trait itself, which is the phenotype.
In this case, an allele (gene variant) is responsible for the resistance of Red Blood cells and regulates oxygen carried by them. The phenotype is the resistance that the RBC's possess and its reduced ability to carry oxygen but the combination of alleles responsible for that trait is the GENOTYPE.
This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.
