What transpires in a hypersensitive reaction of type II?An antibody-mediated immune response is referred to as a type II hypersensitivity reaction when antibodies (IgG or IgM) are directed against extracellular matrix antigens and cause cellular death, tissue damage, or functional loss.
What transpires in a type II hypersensitivity reaction to cells that contain incompatible antigens?Cells are destroyed by antibodies in type II hypersensitivity reactions. Blood-transfusion responses, in which host antibodies interact with foreign antigens on incompatible transfused blood cells and facilitate the death of these cells, are the greatest examples of this type of reaction.

3. can be triggered by airborne substances, foods or common bacteria and viruses
6. spasms can cause wheezing
8. excess mucus in the body
3. Airborne diseases are illnesses spread by tiny pathogens in the air. These can be bacteria, fungi, or viruses, but they are all transmitted through airborne contact. In most cases, an airborne disease is contracted when someone breathes in infected air.
6. If you have a respiratory problem, such as asthma, these muscles can contract and narrow your airway. When that happens, it's called a bronchial spasm, or a bronchospasm. During a bronchial spasm, breathing becomes more difficult. You may find yourself wheezing as you try to catch your breath.
8. What causes excessive mucus? Smoking or exposure to an irritant in the air may cause you to produce more mucus than usual. If the mucus is clear, you might have allergies. Other conditions that could cause excess mucus include bronchitis, chronic obstructive pulmonary disease, and cystic fibrosis.

why might a species' "optimal" phenotype remain unchanged for long periods of time, resulting in apparent evolutionary stasis?
Species remain unchanged for long time resulting in habitat tracking
What is habitat tracking ?
The way in which a species reacts to environmental change can range from adaptation to the new circumstances, through dispersal to areas with better biological settings (a process known as habitat tracking), to extinction.
Species that traveled farther during their existence survived longer, according to a phylogenetically explicit examination of habitat tracking in Caenozoic big mammals. We demonstrated that the longest distance was preferentially covered just before extinction by dividing the fossil record into equal time periods. This affirms that habitat monitoring is a critical response to environmental change and that it causes a species' survival to be prolonged.

In corn plants, normal height (h) is dominant over short height (h). Complete a hybrid (heterozygous) cross.
A mating experiment between two organisms that are equally hybrid for two traits is referred to as a dihybrid cross.
When two heterozygotes are crossed, the anticipated genotype ratio is 1 (homozygous dominant): 2 (heterozygous): 1. (homozygous recessive). When a phenotypic ratio of 2:1 is seen, a deadly allele is presumably present.
H - Height in inches
short height, h
Heterozygous for H
Heterozygotes would be involved in the cross Hh x Hh.
Hh x Hh
I pronounce: HH Hh Hh hh
Considering that H trumps h;
Both HH and Hh would produce normal-height phenotypes.
A short height will arise from the hh trait.

The percentage change in the incidence rate between 1990 and 2000 is 23.3%.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
From the information, in 1990 the incidence rate for lung cancer in males in Great Britain was 150.8 per 100 000 and in 2000 it was 115.7 per 100 000.
The percentage change in the incidence rate between 1990 and 2000 will be:
= (150.8 - 115.7) / 150.8 × 100
= 35.1 / 150.8 × 100

this part of the middle ear vibrates and stimulates the bones of the ossicles when it perceives sounds waves.
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
Vibrations from the eardrum place the ossicles into motion. The ossicles are actually tiny bones in the human body. These vibrations then travels to 3 tiny bones inside the middle ear called the ossicles. The ossicles helps in amplification of sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).

Energy carriers that are made during the first two steps of cellular
respiration used by the last step in the process To deliver electrons to electron transport chains
Explain cellular respiration.
Through the process of cellular respiration, which involves combining oxygen with food molecules, organisms direct the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste, they are able to maintain their own existence. Adenosine triphosphate (ATP), an energy-rich compound that absorbs the chemical energy released from the breakdown of food molecules and releases it to power other cellular processes, is one goal of the degradation of foodstuffs.
The glycolysis , tricarboxylic acid cycle (TCA cycle and oxidative phosphorylation can be considered the three primary metabolic stages or steps that make up the entire process.
A glucose molecule is broken down into two pyruvate (pyruvic acid) molecules during a process known as glycolysis, which occurs in the majority of cells. Glycolysis produces energy that is captured and stored in ATP as it breaks down glucose and other organic fuel molecules from carbohydrates, fats, and proteins. The substance nicotinamide adenine dinucleotide (NAD+) is additionally changed into NADH during this process.
The breakdown, or catabolism, of organic fuel molecules is largely regulated by the TCA cycle, also referred to as the Krebs or citric acid cycle. The compounds NAD+ and flavin adenine dinucleotide (FAD), however, are responsible for capturing the majority of the energy produced by the TCA cycle and turning it into ATP.
Each pair of hydrogen atoms taken from NADH and FADH2 during the oxidative phosphorylation stage contributes a pair of electrons that, when used by a succession of iron-containing hemoproteins called cytochromes, finally convert one atom of oxygen to produce water. The sequence of steps by which electrons travel to oxygen enables a steady reduction in the electrons' energy. Sometimes referred to as the electron transport chain, this phase of the oxidative phosphorylation process.

Dispersal, which happens when a few individuals of a species travel to a different region, or vicariance, which happens when a natural occurrence, such the development of a river or valley, physically divides species, are the two ways that allopatric speciation events might take place.
