The frequency of a1a2 genotype is a population is 0.4.

Formula to calculate the a1a2 genotype frequency is: -

[tex]\frac{a1a2 genotype}{total genotype}[/tex] = [tex]\frac{80}{20 + 80 +100}[/tex] = 0.4

Genotype- The word "genotype" refers to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different versions of a gene, that an organism carries in a more specific meaning.

Population- A population is described as a collection of people who belong to the same species and cohabit a certain region. In order to survive throughout time, individuals of a population frequently rely on the same resources, are susceptible to the same environmental restrictions, and affect the availability of other members.

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. One hormone could have opposing effects on different organs as e. cells in the different tissues would have epinephrine receptors coupled to different signaling pathways.

It is through the cell signaling pathway that a hormone is able to cause a cell to cause an action. The activity of a cell that is performed under the influence of a hormone depends on cell signaling.

A hormone might cause two opposing actions for different cell types depending on how the cell perceives the hormone through its receptors. As muscle cells require glycogen hence epinephrine couples with receptors that promote this activity in muscle cells through cell signaling. However, it inhibits this activity in the salivary gland due to the coupling with a receptor of salivary gland cells that inhibit this pathway.

The activity of a hormone through cell signaling helps the cell to complete its specialized functions.

Although a part of your question is missing, you might be referring to this question:

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. How could one hormone have opposing effects on different organs?

a. Cells in the tissues that are suppressed do not express an epinephrine receptor.

b. Cells in responsive tissues have signal transduction pathways.

c. Only responsive tissues are exposed to the epinephrine in the blood stream.

d. Cells in tissues that are not responsive contain enzymes that break down epinephrine when it enters the cell.

The amount of money that was raised for conservation from the sale of firearms is = $8,455,000,000

The number if firearms sold in U.S. during 2020= 19,000,000

The cost of an average firearm = $500

The tax collected per firearm by Pittman-Robertson Act = 11%.

That is, 11% of $500

= 11×500/100

= $55 for every firearm

The total cost of 19million firearms

= 19,000,000 × 500

= 9,500,000,000

The total tax collected form 19 million firearms,

= 55 × 19,000,000

= 1,045,000,000

The amount raised for conservation;

= 9,500,000,000 - 1,045,000,000

= $8,455,000,000.

Answer:

To calculate the amount of money raised for conservation from the sale of firearms during 2020, we'll follow these steps:

Step 1: Calculate the total revenue generated from firearm sales.

Total revenue = Number of firearms sold * Price per firearm

Total revenue = 19,000,000 * $500

Total revenue = $9,500,000,000

Step 2: Calculate the amount of excise tax collected.

Excise tax = Total revenue * Excise tax rate

Excise tax = $9,500,000,000 * 0.11

Excise tax = $1,045,000,000

Therefore, the amount of money raised for conservation from the sale of firearms during 2020, based on the given information, is $1,045,000,000.

The pseudostratified epithelium is the type of epithelium that is composed of a single layer of cells that are attached to a basement membrane, but not all the cells reach the apical surface of the epithelium.

Columnar epithelium cells are the types of cells that form the pseudostratified epithelium. This kind of epithelium is made from a single layer of cells although it appears to be multilayered because of stratification. The single layer of the pseudostratified epithelium cells is attached to the basement membrane. However, not all cells from the pseudostratified epithelium reach the apical surface of the epithelium.

These pseudostratified epithelium cells also show the property of either possessing cilia or being nonciliated.

The synthesis of sugar molecules through the process of photosynthesis requires energy absorbed from sunlight. Bearing this in mind, what kind of reaction is photosynthesis? A particular chemical reaction is exergonic.

What is Photosynthesis?

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Have a great day! :)

The synthesis of sugar molecules through photosynthesis requires energy to be absorbed from the sunlight. Bearing this in mind, photosynthesis is an exergonic chemical reaction.

Photosynthesis is the process of formation of sugars in the chloroplast of plant cells. The synthesis requires energy which is absorbed from the sunlight. This sunlight is trapped in the chlorophyll pigment of plant cells. This energy converts carbon dioxide and water into sugars.

Photosynthesis is an exergonic reaction as this reaction releases free energy in the form of sugars (carbohydrates) in the process of the reaction. In exergonic reactions, energy is produced hence the reaction occurs spontaneously. The reactants does not require any energy to react and form product.

The membrane is composed of phospholipids that will form a lipid bilayer through which products pass through it.

The plasma membrane is made up, among other components, of phospholipids that will generate a phospholipid bilayer due to its amphipathic nature. Due to its conformation, different molecules will not find it easy to pass through the plasmatic membrane into and out of the cell, for this reason, the cell will have types of transport to be able to allow the passage of substances.

Within these forms of transport, we find endocytosis, which is when the cell enters bulky materials inside the cell, exocytosis, which is when it takes bulky materials out of the cell, is the facilitated diffusion by which molecules pass without spending energy thanks to its concentration gradient and active transport in which the channels need ATP to be able to pass the molecules through it since it is done against its concentration gradient.
