Where does the water enter the plant in photosynthesis?
Answers
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

describe the basis of rights according to natural rights theorists
Answers
The basis of rights according to natural rights theorists is the belief that there are certain rights that are inherent to human beings, regardless of their race, gender, nationality, or any other characteristic. These rights are considered to be natural, in the sense that they exist independently of any human-made laws or institutions.
They are often seen as deriving from human nature itself, or from some transcendent source such as God or the universe. Natural rights theorists is that these rights are fundamental to human dignity and well-being, and that they provide a basis for moral and political obligations. Some of the most commonly recognized natural rights include the right to life, liberty, and property, as well as freedom of conscience, speech, and association.
Natural rights theorists argue that these rights are not granted by governments, but are instead inherent to human beings themselves. This means that governments have a duty to protect these rights, but they cannot create or revoke them. Natural rights theorists also contend that individuals have a right to resist unjust laws or governments that violate these rights, since such actions are contrary to natural law.

Identify the driving force and molecules/ particles for the following membrane transport mechanisms. Diffusion, Filtration, Osmosis, Primary Active transport.
Answers
1. Diffusion: The driving force for diffusion is the concentration gradient. Molecules involved include small, nonpolar molecules like oxygen (O2) and carbon dioxide (CO2).
2. Filtration: The driving force for filtration is hydrostatic pressure, Small molecules, ions, and water are typically involved in filtration.
3. Osmosis: The driving force for osmosis is the concentration gradient. In osmosis, water molecules are involved.
4. Primary Active Transport: The driving force for primary active transport is ATP , This process involves carrier proteins, such as the sodium-potassium pump.
- Diffusion: The driving force behind diffusion is the concentration gradient, which refers to the difference in concentration of a substance between two areas.
Molecules or particles will naturally move from an area of high concentration to an area of low concentration in order to balance out this gradient and reach equilibrium. No energy input is required for diffusion to occur.
- Filtration: The driving force behind filtration is pressure, which pushes molecules or particles through a membrane. This pressure can come from a variety of sources, such as gravity, mechanical forces, or differences in fluid pressure on either side of the membrane.
Filtration can occur passively or actively, depending on the specific mechanism involved.
- Osmosis: The driving force behind osmosis is also the concentration gradient, but in this case it specifically refers to the concentration of water molecules.
Water will move from an area of low solute concentration (i.e. high water concentration) to an area of high solute concentration (i.e. low water concentration) in order to balance out this gradient and reach equilibrium.
Again, no energy input is required for osmosis to occur.
- Primary Active Transport: The driving force behind primary active transport is the use of ATP (adenosine triphosphate) energy to move molecules or ions against their concentration gradient.
This process involves specific proteins called pumps that use energy to transport molecules or ions from an area of low concentration to an area of high concentration.
Primary active transport is a type of active transport, which means that energy input is required for the process to occur.

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?.
Answers
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.

Cutthroat hindrance is a sort of catalyst restraint wherein the inhibitor predicaments to the dynamic site on the chemical. This forestalls the restricting of the substrate to the chemical and subsequently influences the pace of the breakdown of the compound substrate complex. Cutthroat inhibitors tie reversibly to the dynamic site of the chemical to shape a compound inhibitor complex. In this, the most extreme speed (V max ) is unaltered while Km is expanded as the inhibitor slows down the limiting of the substrate and this hindrance can be overwhelmed by expanding the substrate fixation. In this, the inhibitor particle isn't synthetically different from the compound.

Start with a carbon backbone: C-C-C-C-C-C-C-C-C-C-C-C-C-C.This gives you 14 carbon atoms connected in a straight chain.To introduce double bonds, we need to remove two hydrogen atoms and create double bonds between adjacent carbon atoms. Let's choose the 3rd and 4th carbon atoms from the left.Remove two hydrogen atoms from the 3rd and 4th carbon atoms: C=C-C=C-C-C-C-C-C-C-C-C-C.Now, we need to balance the number of hydrogen atoms. Each carbon atom should have four bonds. Since we removed two hydrogen atoms, we need to add two double bonds.Introduce two double bonds between the 1st and 2nd carbon atoms and between the 6th and 7th carbon atoms: C=C-C=C-C=C-C-C-C-C-C-C-C.To complete the formula, add hydrogen atoms to each carbon atom to satisfy the valency.

What is uncoiled,stringy DNAcalled?
A. Chromatin
B. Chromosomes
C. Chlorophyll
D. Sister Chromatids
Answers
Uncoiled, stringy DNA is called chromatin. Chromatin is a complex of DNA, proteins, and RNA that make up the genetic material of eukaryotic cells. In non-dividing cells, chromatin is uncoiled and spread throughout the nucleus.
It can be organized into distinct regions, such as euchromatin, which is less condensed and more transcriptionally active, or heterochromatin, which is more condensed and transcriptionally silent.
During cell division, chromatin undergoes a series of changes to form visible chromosomes. The chromatin condenses and becomes more tightly packed, eventually forming distinct chromosomes composed of two sister chromatids held together by a centromere. Chromosomes are visible under a microscope and are used to study genetic material, inheritance, and genetic disorders. Therefore, chromatin is the correct answer to the question.

What makes up genes? Explain in 1 paragraph please
Answers
Answer: Genes are made up of DNA
Explanation: Genes are made up of DNA . to be more precise each gene is made out of possibly 25 000 dna to 2 million dna.
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Which leads reflect ischemic changes in the right coronary artery?
Answers
Leads II, III, and aVF reflect ischemic changes in the right coronary artery. The leads II, III, and aVF are known as the inferior leads in an electrocardiogram (ECG).
These leads specifically monitor the electrical activity of the heart's inferior wall, which is primarily supplied by the right coronary artery (RCA). Ischemic changes in the RCA can be detected by observing abnormalities in these leads.
The RCA is responsible for supplying blood to the inferior part of the heart, including the inferior wall and the posterior part of the septum. When there is a blockage or reduced blood flow in the RCA due to ischemia, it can lead to changes in the ECG recordings of the inferior leads (II, III, and aVF).
These changes may include ST-segment depression, T-wave inversion, or the development of pathological Q-waves, indicating myocardial ischemia or infarction in the area supplied by the RCA.
Therefore, by analyzing the ECG findings in leads II, III, and aVF, healthcare professionals can identify and assess the presence of ischemic changes in the right coronary artery territory, providing valuable diagnostic information for patient care.

The correct order of the steps to trace the process of respiration is:
Air moves from the atmosphere into the lungs.
Gas is exchanged between air in the alveoli and blood in the pulmonary capillaries.
Gas is exchanged between tissue cells and blood in the systemic capillaries.
Air flows out of the lungs back to the atmosphere.
Respiration is a vital process for living organisms as it provides the necessary oxygen for cellular energy production and removes carbon dioxide, which is a waste product of cellular metabolism. It plays a crucial role in maintaining the balance of gases and pH in the body, and disruptions in respiratory function can have serious health consequences.
This represents the pathway of air and gas exchange during respiration, starting with inhalation of air into the lungs, followed by gas exchange in the alveoli of the lungs where oxygen is taken up by the blood and carbon dioxide is released, then transport of oxygenated blood to the systemic capillaries where oxygen is delivered to tissues and carbon dioxide is picked up, and finally exhalation of air containing carbon dioxide back into the atmosphere.

To digest carbohydrates, digestive enzymes must first break them down into their subunits, the enzymes must catalyze the hydrolysis of glycosidic bonds.
All disaccharides and complex carbohydrates are intended to be broken down into monosaccharides for absorption, albeit some (such as fibre) are not entirely absorbed in the small intestine. Amylase from saliva is released while chewing, which triggers the start of digestion in the mouth.
The breakdown of carbohydrates is greatly aided by enzymes. Starch is broken down into smaller sugars like maltose and glucose by the enzyme amylase. These sugars are further disassembled into their constituent sugar molecules by other enzymes like lactase and sucrase.
