B) Sugars are transported from the leaves to the roots.
Leaves- Simple leaves have an entirely undivided blade, but they can also have lobes in which the gaps between the lobes don't reach the main vein. In a complex leaf, each leaf blade is split into leaflets, each of which has a stalk and is connected to the main vein.
Root- A plant's roots serve a number of vital purposes. The plant is anchored in place by its roots, which fend off the forces of wind, water movement, and mud flow. In order to transport oxygen, water, and nutrients upward through into the plant to a stems, leaves, and flowers, the root system absorbs these elements from the soil.

The process occurring at the sensory receptors that convert physical energy into coded neural activity that the nervous system can process is called c. sensory transduction
In the field of science, we can define sensory transduction as a process by which a change in the physical environment is recognized by the sensory receptors. This information is changed into electrical signals that are transported along the neurons. The neurons transmit these action potentials to the CNS which interprets it and sends signals for producing a response through the effector neurons.
The sensory receptors detect any kind of environmental change and the physical energy of the neurons changes into a neural activity that is initiated by the nervous system in recognition of this change by the sensory receptors.

At the end of the electron transport chain, where is the light energy that was absorbed and converted by chlorophyll stored?.
At the end of the electron transport chain, the light energy is stored in ATP and NADPH molecules.
What are the steps of the electron transport chain reaction?In Photosystem II, chlorophyll is used to store radiant energy.
The energy level of the electrons provided by the water molecules increases when the pigment molecules absorb light.
The excited electrons travel from Photosystem II to Photosystem I at a lower energy level via the electron transport chain.
New electrons are taken out of the water molecules to replace the excited electrons as they leave photosystem II.
The photosystem I electrons are transferred to another electron acceptor by the absorption of light energy, where they are then transported back and used to create NADPH molecules.
As electrons leave Photosystem I, new electrons from Photosystem II enter to take their place.
Hydrogen ions are still present in the thylakoid lumen after the water molecule disintegrates, and the ATP synthase pumps them to the stroma.
ATP molecules are made using the energy that has been released.
Hydrogen ions go back from the stroma to the thylakoid compartment.
Therefore, at the end of the electron transport chain, the light energy is stored in ATP and NADPH molecules.

Explanation:
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.

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.

What do you mean by protein?Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Among many tasks that proteins carry out in living things include catalyzing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another. The primary way that the proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into the certain 3D structure that controls its activity.
A polypeptide is an ordered sequence of amino acid residues. At least one lengthy polypeptide is present in every protein. Less than 20–30 residue polypeptides are frequently referred to as peptides and are rarely thought of as proteins. Peptide bonds and nearby amino acid residues hold the individual amino acid residues together. The sequence of a gene, which is encoded in the genetic code, determines the arrangement of amino acid residues in a protein.
The genetic code typically only defines the 20 conventional amino acids, but in some organisms, it may also include selenocysteine and—in some archaea—pyrrolysine. The residues in a protein are frequently chemically altered by post-translational modification shortly after or even during synthesis, which modifies the physical and chemical characteristics, folding, stability, activity, and ultimately the function of the proteins. Non-peptide groups, often known as cofactors or prosthetic groups, are sometimes added to proteins. Additionally, proteins can cooperate to carry out certain tasks, and they frequently join forces to create stable protein complexes.

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.
