Explanation:

The first step in calculating the amount of the 2020 dividend that was distributed to preferred shareholders is to determine the total amount of outstanding dividends.

In 2019, West paid a dividend of $4,000, which was presumably distributed to both common and preferred shareholders. In 2020, West paid a dividend of $20,000, so the total amount of outstanding dividends is $24,000 ($4,000 + $20,000). Next, we need to calculate how much of the outstanding dividends were allocated to preferred shareholders. According to the question, West has 10,000 shares of non-cumulative preferred stock with a par value of $10 per share and a dividend rate of 5%. This means that each preferred share is entitled to a dividend of $0.50 ($10 x 5%) per year. The total dividend owed to preferred shareholders is therefore $5,000 ($0.50 x 10,000 shares). Since the outstanding dividends are $24,000 and the amount owed to preferred shareholders is $5,000, the remaining $19,000 must be allocated to common shareholders.

Solution:

The cardiovascular system consists of two pumps (left and right ventricle) and two series of circuits:

Pulmonary circuit and systemic circuit.

The systemic circuit:

This circuit begins in one of the great vessels, the aorta, which branches into smaller vessels to the capillaries that finally reach the organs.

Now, the vascular components include arteries, arterioles, and capillaries:

Arteries: they are thick-walled vessels, the blood that circulates in these vessels has high pressure and they carry oxygenated blood to the body's tissues.

Arterioles: they are branches of the arteries.

Capillaries: they have larger surface areas and cross-sections and are the sites of exchange for nutrients, water, and gases.

on the other hand, the vascular components also include the venous circuit, in this circuit, the venules (smaller veins) join to form larger veins until the larger vein, the vena cava, returns blood to the heart:

Veins: thin-walled vessels where blood circulates with low pressure. These vessels contain most of the blood that flows in the cardiovascular system.

Venules: they are the component with the highest permeability in the microcirculation.

Pulmonary circuit:

In the pulmonary circuit, deoxygenated blood leaves the heart's right ventricle and passes into the pulmonary artery (pulmonary artery trunk). The pulmonary artery trunk divides into the right and left pulmonary arteries.

The right and left pulmonary arteries carry deoxygenated blood to the arterioles and capillary beds in the lungs. In this location (lungs), carbon dioxide is released and oxygen is absorbed. The oxygenated blood then passes from the capillary beds through the venules into the pulmonary veins. The pulmonary veins carry it to the left atrium of the heart. The pulmonary arteries are the only arteries that carry deoxygenated blood, and the pulmonary veins are the only veins that carry oxygenated blood.

The heart:

The heart is located between the lungs in the center of the chest (inferior mediastinum), behind, and slightly to the left of the breastbone.

The heart is wrapped in a membrane composed of two layers, this membrane is called the pericardium.

The outer layer of the pericardium surrounds the source of the major blood vessels of the heart and is attached to the spine and diaphragm by ligaments.

The inner layer of the pericardium is attached to the heart muscle (myocardium). A layer of fluid separates the two layers of the membrane, allowing the heart to move as it beats while remaining attached to the body.

The heart has four chambers.

The upper chambers are called atriums and there are two of them: left atrium and right atrium.

On the other hand, the lower chambers are also two and are called left ventricle" and "right ventricle.

A muscular wall called the septum separates the left and right atria and the left and right ventricles.

The left ventricle is the largest and strongest chamber in the heart. In fact, the walls of the left ventricle are strong enough to push blood through the aortic valve to the rest of the body.

Valves are those that control the flow of blood in the heart. These valves are 4.

The tricuspid valve controls blood flow between the right atrium and the right ventricle.

The pulmonary valve controls blood flow from the right ventricle to the pulmonary arteries. Note that the pulmonary arteries carry blood to the lungs to oxygenate this blood.

The mitral valve allows oxygenated blood from the lungs to pass from the left atrium to the left ventricle.

The aortic valve allows oxygen to pass from the left ventricle to the aorta, the largest artery in the body, which carries blood to the rest of the body.

On the other hand, the heart works through a special network of the myocardium, which stimulates the heart to contract. This electrical signal originates from the sinoatrial (SA) node located in the upper part of the right atrium.

Electrical impulses from the sinoatrial node travel through the muscle fibers of the atria and ventricles, stimulating their contraction.

Decreasing free calcium ions would reduce the postsynaptic responses in the nervous system with acetylcholine.

Free calcium ions play a crucial role in the nervous system by facilitating the release of neurotransmitters such as acetylcholine.

When calcium ion levels decrease, it leads to a reduced release of acetylcholine at the synaptic cleft.

Consequently, this reduction affects the strength of postsynaptic responses, as there are fewer acetylcholine molecules available to bind with receptors on the postsynaptic membrane.

Hence, lower levels of free calcium ions negatively impact the postsynaptic responses in the nervous system with acetylcholine due to a decreased release of the neurotransmitter.

The term for a group of related taxa that are found within the same V-shaped portion of a cladogram is a clade. A clade is a group of organisms that share a common ancestor and includes all of its descendants.

Cladograms are branching diagrams that show the evolutionary relationships among organisms based on their shared characteristics. In a cladogram, each branching point represents a common ancestor, and the groups of organisms that share a common ancestor are organized into nested clades.

Clades are defined by synapomorphies, which are shared derived characteristics that are present in all members of the clade but absent in more distantly related organisms. By identifying and analyzing synapomorphies, scientists can determine the evolutionary relationships among organisms and construct cladograms that reflect their shared history.

Clades can be nested within larger clades, forming a hierarchical classification system that reflects the evolutionary relationships among all living organisms.

The correct statement about the atoms in ammonia ( NH₃ ) is ; ( A ) Each hydrogen atom has a partial positive charge : the nitrogen atom has a partial negative charge

Since Nitrogen is more electronegative than hydrogen in ammonia each of the hydrogen atom will have a partial positive charge while the nitrogen atom will have a partial negative charge.

The type of bonding that exists in NH₃ is covalent bonding since Hydrogen and Nitrogen are both Non-metallic. while the bonding between hydrogen atoms is a dipole to dipole bonding and not completely a covalent bond.

Hence we can conclude that in NH₃ Each hydrogen atom has a partial positive charge while the nitrogen atom has a partial negative charge

 a. A plant with the genotype dr/dr produces two types of gametes: d-r and d-r. The parental gametes are d-r and d-r, while the recombinant gametes are d-r and d-r. The frequency of each gamete genotype is equal, since they are produced through independent assortment during meiosis. Therefore, the frequency of both parental and recombinant gametes is 50%.

b. A plant with the genotype Dr/Dr produces four types of gametes: D-r, d-R, D-R, and d-r. The parental gametes are D-R and d-r, while the recombinant gametes are D-r and d-R. The frequency of each gamete genotype can be calculated using the formula: frequency = (number of that genotype/total number of gametes) x 100%. Therefore, the frequency of D-R and d-r gametes (parental gametes) is 25% each, while the frequency of D-r and d-R gametes (recombinant gametes) is 12.5% each.

a. For a plant with the genotype Dr/Dr (homozygous for both dominant traits):
Since the alleles are syntenic, we can analyze their combinations during gamete formation. The possible gamete genotypes would be:

1. Parental Gametes (no recombination):
- Dr (tall and round) - frequency: 82%
2. Recombinant Gametes (recombination occurred):
- Dr (tall and oval) - frequency: 9%
- dR (short and round) - frequency: 9%

b. For a plant with the genotype dr/dr (homozygous for both recessive traits):
In this case, the plant can only produce one type of gamete since both alleles are recessive:

1. Parental Gamete (no recombination):
- dr (short and oval) - frequency: 100%

There will be no recombinant gametes in this case since the plant is homozygous for both recessive traits.

Answer:

The sequence would be ATTCATTCA.

Explanation:

Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.

So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files.

Warts may disappear over time without treatment. This is due to the natural functioning of the immune system.

What are warts?

Warts are small growths on the skin caused by a viral infection. There are many types of warts, and they are typically classified according to the area of the body where they are located: Common warts (verruca vulgaris) - Most frequently found on the hands and feet, but can also appear on other parts of the body.

Plantar warts - Typically located on the soles of the feet.

Filiform warts - Most often found around the nose and mouth.Flat warts (verruca plana) - Generally seen on the face and legs, but can also appear in other places. Usually, warts will disappear on their own within a few months or years, as the immune system becomes more aware of the virus and how to fight it off.

However, it may take several years for warts to disappear entirely, and they may reappear in the same spot or elsewhere on the body.

D aerobic respiration and fermentation producing carbon dioxide and ethanol

Aerobic respiration and fermentation producing carbon dioxide and ethanol are useful in increasing the amount of gas in a food product. Therefore, option (D) is correct.

Both aerobic respiration and fermentation are separate processes that living organisms employ to generate energy. Aerobic respiration is the more common of the two. The most effective method of respiration is known as aerobic respiration, but it can only take place in the presence of oxygen. Fermentation is a process that is less efficient, yet it can take place in the absence of oxygen.

Because fermentation generates less ATP for each molecule of glucose than aerobic respiration does, fermentation is a less efficient metabolic pathway. Fermentation, on the other hand, does not call for the presence of oxygen, whereas aerobic respiration does. Which process is used will be determined by how much oxygen is available. Aerobic respiration will take place if oxygen is available in the environment. Fermentation will take place if there is an absence of oxygen.
