The diploid zygote forms at fertilization (d) in seed plant reproduction.

The megagametophyte, which creates the egg cell, is a component of the female reproductive structure known as the ovule in seed plant reproduction. The male gametophyte, which generates the sperm cell, is found in the pollen grain, which is the male reproductive structure. When a pollen grain touches the stigma of a female reproductive structure, it starts to build a pollen tube down the style, enabling the sperm cell to contact the egg cell inside the ovule. This process is known as pollination.

A diploid zygote is created during fertilisation as a result of the union of the sperm and egg cells. This zygote then proceeds through mitotic division to create an embryo, which later matures into a seed.

Answer: a

Explanation:

Many deciduous trees, such as sycamores and aspens, drop their leaves each year. After some time, the nutrients from the leaves become part of the soil and are available again. These type of the nutrients are made available to the soil again by the decomposers.

Deciduous trees are the trees that shed their leaves that sheds off their leaves once in a year usually in autumn.

Decompsers are the organisms that feed on the dead living organisms and their waste to produce energy for themselves including dead matter of plants, animals, fallen off leaves, excreta and other items.

They release the nutrients that are sequestrated in organic matter into the soil so that it can be used up by the plants.

The statement "NSAIDs prevent the production of prostaglandins by physically blocking the movement of cox enzymes, or attaching to cox enzymes, changing their chemical structure and function" is true.

NSAIDs, or nonsteroidal anti-inflammatory drugs, work by inhibiting the action of cyclooxygenase (COX) enzymes. Prostaglandins are lipid compounds that play a role in inflammation, pain, and fever. COX enzymes are responsible for the synthesis of prostaglandins. NSAIDs can prevent the production of prostaglandins by two mechanisms. First, they physically block the movement of COX enzymes, preventing them from binding to their substrate and catalyzing the formation of prostaglandins. This reduces the overall production of prostaglandins.

Second, NSAIDs can also attach to COX enzymes, leading to a change in their chemical structure and function. This alteration in the enzyme's structure makes it unable to carry out its normal function of prostaglandin synthesis.
By interfering with the activity of COX enzymes, NSAIDs help reduce inflammation, relieve pain, and lower fever. It's important to note that different NSAIDs may have varying degrees of selectivity for COX-1 and COX-2 enzymes, which can affect their side effect profile.

Photosynthesis is a biological process whereby green plants are able to make use of inorganic materials such as carbon dioxide and water to synthesize carbohydrates in the presence of solar radiation.

The carbon dioxide diffuses through the tissues of green plants such as leaves or stems while the water is conducted into the body of the plant from the root. Solar energy is utilized to drive the process while oxygen gas is liberated as a by-product. The overall equation of the reaction is as follows:

\(6CO_2 + 6H_2O -- > C_6H_{12}O_6 + 6O_2\)

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.

Answer: We can tell how life existed on earth and how different plants and animals are related to each other. Often we can work out how and how and where they lived, and use this information to find out  about ancient environments. Fossils can tell us about the past.

Explanation

Answer:

Law of inertia, also known as Newton’s first law of motion states that An object will continue to be in the state of rest or in a state of motion unless an external force acts on it. We have read about the Aristotle fallacy, as per which an external force is always required to keep a body in motion.

Explanation:

Galileo’s Free Fall Experiment

The most accepted theory of motion in Western philosophy, prior to the Renaissance, was the Aristotelian theory which stated that “In the absence of external power, all objects would come to rest that moving objects only continue to move so long as there is a power inducing them to do so. ” Despite its general acceptance, the Aristotelian theory was discredited by several notable philosophers. Later, Galileo refined the theory of inertia.

How did Galileo Explain Inertia?

Galileo hypothesized that a falling object gains an equal amount of velocity in equal intervals of time. This also means that the speed increases at a constant rate as it falls. But, there was a problem in testing this hypothesis: it was impossible for Galileo to observe the object’s free-falling motion and at the time, technology was unable to record such high speeds. As a result, Galileo attempted to decelerate its motion by replacing the falling object with a ball rolling down an inclined plane. Since free-falling is basically equivalent to a completely vertical ramp, he assumed that a ball rolling down a ramp would speed up in the exact same way as a falling ball would.

Using a water clock, Galileo measured the time it took for the rolling ball to reach a known distance down the inclined plane. After several trials, it was observed that the time it took for the ball to roll the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. In short, if you were to double the amount of distance the ball traveled, it would travel four times as far. Through this experiment, Galileo concluded that

If an object is released from rest and gains speed at a steady rate (as it would in free-fall or when rolling down an inclined plane), then the total distance, s, traveled by the object is proportional to the time squared needed for that travel.

What is Succession ?

Succession is the process through which a region's species and habitat mix changes over time.

There are two types of biological succession: primary and secondary.

When bare rock or fresh land are exposed, primary succession occurs, creating an environment that can support the earliest colonization of an ecosystem.

The ecological succession known as secondary succession takes place when certain plants and animals still remain after the primary succession has been interrupted.

What are the stages of Succession ?

Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization are the five stages of succession. At the same location, a succession of biotic communities organically emerge one after another until the Climax stage is reached. In their early stages, biotic communities evolve slowly.

Therefore the overall diversity of species is constant.
