You can do golden rice. It was genetically modified to produce beta carotene, which rice does not usually have. When metabolized by the body beta carotene is turned to vitamin A which is essential to human vision, immune systems, and healthier skin
Blood flows through an artery that is partially blocked. as the blood moves from the wider region into the narrow region, alternately increases and then decreases.
<h3>What is the purpose of blood flow in heart?</h3>
The removal of positive charge by electrochemical gradients causes the membrane potential of the cell to shift more strongly in the direction of the equilibrium potential for potassium.
The membrane would become more negative as potassium permeability through the membrane increased. Given that potassium is a positively-charged ion and that the intracellular environment has a net negative charge, enhancing the membrane's permeability would result in a more negative membrane.
For instance, the amplitude of the potassium concentration gradient across the myocyte decreases as the external potassium level rises, lowering the resting membrane potential.

<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
The correct answer is that it is an organism's habitat and inherited traits that determine its niche.
The principle of competitive exclusion states that the two species cannot hold the similar niche in the same habitat. A niche of an organism is predicted by its habitat that is its physical surrounding. The inherited traits and adaptation enhances the organism's chances of survival, and it also predicts a niche of an organism.
