What is the process of cellular respiration?The process by which organisms combine oxygen with food molecules, rerouting the chemical energy contained in these molecules into life-sustaining processes while excreting carbon dioxide and water as waste, is known as cellular respiration.
Organisms mix oxygen with food molecules during cellular respiration, directing the chemical energy in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste.
While cells are respiring, oxygen may be present or not. However, because the cell seems to "respire" by ingesting molecular oxygen (as an electron acceptor) and releasing carbon dioxide, the process is essentially known as "cellular respiration" (as an end product).

Calculate the force the man in applying to the van.
The force man is applying to push a van of 2000kg and acceleration of 0.05m/s/s is 100 N.
What is force?Force can move a body that is at rest and can also stop a moving body or slow it down. It can accelerate the speed of a moving body and can change the direction along with its shape and size of a moving body
The force is defined by Newton's second law of motion:
Force exerted by an object is equal to mass multiplied by acceleration
F = m ⨉ a.
SI units are Newtons for force, kilograms for mass, and meters per second squared for acceleration. A force can change velocity of the object with mass. It is a vector quantity as it has both magnitude and direction.
Given mass is 2000 kg and acceleration 0.05 m/s/s,
we can find force using formula:
F= m * a

What is Hypertension?A persistent medical disease called hypertension, often known as high blood pressure, causes the condition in which the blood to be greater than it should be. The heart must work harder than usual to pump more blood through all the blood arteries in this situation.
Based upon what the heart is doing, the pressure within the arteries varies. The pressure rises as the heart pumps blood through the arteries by contracting. The pressure drops when the heart unwinds. Systolic blood pressure is the maximum pressure recorded during a blood pressure reading. Diastolic blood pressure is the lowest pressure.

Between each presynaptic and postsynaptic neuron is a Synaptic cleft that is the fluid-filled space between them. Each presynaptic neuron releases a Neurotransmitter that binds with receptors in the Postsynaptic segment of a postsynaptic neuron.
The gap between the pre-and postsynaptic cells, also known as the synaptic cleft or synaptic gap, is around 20 nm (0.02 ) broad. Rapid changes in neurotransmitter concentration are made possible by the cleft's tiny volume. The primary purpose of the synaptic cleft is to create a place for the chemical transfer of nervous system information. These signals can also be regulated thanks to the synaptic cleft.
A postsynaptic neuron sends signals away from the synapse, whereas a presynaptic neuron sends signals toward a synapse. The synapse, a juncture where the terminal part of the axon contacts another neuron, is where information is transmitted from one neuron to another.

Describe the pathway taken by these molecules of carbon dioxide from the muscle cells to the blood
Explanation:
The blood can transport carbon dioxide in three different ways. Plasma proteins or haemoglobin hold it in place, it is dissolved directly in the blood, or it can be converted into bicarbonate.
Carbon dioxide is primarily transported by the bicarbonate system. The carbon dioxide diffuses into the red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO−3) and H+. The H+ ion binds to haemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. It is called the chloride shift.
The bicarbonate leaves the red blood cells and enters the blood plasma. The lungs transport bicarbonate back into the red blood cells in exchange for chloride. The H+ dissociates from haemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which then catalyzes the reaction to turn carbonic acid back into water and carbon dioxide. As a result, carbon dioxide is expelled from the lungs.

Photosynthesis on the other hand is referred to as the process in which plants manufacture their food in the presence of sunlight and some compound such as water etc.

______ are formed in stars’ cores as a result of fusion.
Ultraviolet waves
Radio waves
Gamma rays
Infrared waves
Gamma rays are formed in stars’ cores as a result of fusion.
Gamma rays are produced during the breakdown of radioactive atomic nuclei and the decay of particular subatomic particles. Gamma rays are also produced via the procedure of pair annihilation, where an electron and its antiparticle, a positron, disappear and two photons are created. Inside the star's core gamma rays are produced through the following steps:
Two protons in the Sun fuse. The pair breaks apart again frequently, but occasionally one of the protons changes into a neutron through the weak nuclear force. With the conversion into a neutron, a positron and neutrino are formed, which results in proton-neutron pair known as deuterium.A third proton crashes with the composed deuterium. This collision influences the construction of a helium-3 nucleus and a gamma ray. These gamma rays emit out from the core of the Sun and are released.Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that exit as two hydrogens.To learn more about gamma ray here

If glucose is the sole energy source for cellular respiration in an animal, what proportion of the carbon dioxide exhaled is derived from oxidation of pyruvate to acetyl coa?.
The proportion of the carbon dioxide exhaled derived from the oxidation of pyruvate to acetyl CoA is 1/3.
Pyruvate is produced by glycolysis in the cytoplasm and its oxidation takes place in the mitochondrial matrix before chemical reactions begin, pyruvate enters the mitochondrion crossing the inner membrane and arriving at the matrix.
Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂
This is the reaction of the conversion of pyruvate into acetyl CoA.
1 molecule of pyruvate is converted into 1 molecule of carbon dioxide.
Also, 2 molecules of pyruvate are converted into 2 molecules of carbon dioxide (as glucose on glycolysis yields 2 molecules of pyruvate).
Acetyl-CoA also contributes to the citric acid cycle and generates two molecules of CO₂.
Pyruvate thus generates a total of 3 molecules of CO₂, whereas glucose generates 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate)
Thus, Fraction = 2/6 = 1/3.
