Answer:
Angiosperms
Explanation:
Angiosperms are important to humans in many ways, but the most significant role of angiosperms is as food. Wheat, rye, corn, and other grains are all harvested from flowering plants.
The answer is Meiosis. Meiosis is involved in the formation of egg and sperm/gametes.
Answer: (B) to function as the final electron acceptor in the electron transport chain.
Explanation:
Oxidative phosphorylation is a process that takes place in cellular respiration. It consists of two component pathways which includes the electron transport chain (etc) and chemiosmosis.
In etc the electrons are passed from one to another molecule, the energy is released by the electrochemical gradient.
In chemiosmosis, the energy stored in the electrochemical gradient is used to produce energy molecules in the form of ATP (Adenosine triphosphate).
The oxygen is present at the end of the etc. It's function is to accept the electrons also picks up the protons to form water. If oxygen is absent then no molecule will accept the electrons, the electron transport chain will stop. There will be no chemiosmosis as the ATP will not be produced in the absence of formation of a electron gradient.
Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

<span>The neuron, a cell
that composes the nervous system. For example a brain, an organ composed
of thousands of neural fibers and glial cells that performs many
important organismic functions.
Neurons are specialised cells that
have dendrites, axons and terminal buttons that sends and receives
stimuli from the environment and transduces it into a meaningful
information and understand the complexities which the brain now
functions. </span>
