Answer:
Organ systems are organs that work together to perform a specific bodily function, so your answer is D
Explanation:
Answer: B and D
Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.
Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.
This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.
Hope this helped.
Answer:
True
Explanation:
According to the law of conservation of mass, mass can not be created nor destroyed.
The implication of this is that the total mass on both sides of the reaction equation must be the same.
Thus, the number of atoms of each element on both sides of the reaction arrow must be the same.
The correct answer is a - cerebrum
The cerebrum, also called cortex is the largest part of the brain. It is divided into four sections, called lobes and these are the frontal lobe, the parietal lobe, occipital lobe and temporal lobe.
Front lobe helps in speech, reasoning, planning, movement , emotions and problem solving.
parietal lobe helps in orientation, and perception of stimuli and movement.
Occipital lobe helps in visual processing.
Temporal lobe helps in memory, speech as well as perception and recognition of auditory stimuli.
