Answer:
Molecules which move against the concentration gradient across the cell membrane employ the mechanism of active transportation.
Explanation:
Normally, permitted molecules moves across the cell membrane of the cell by the process of diffusion and osmosis. This is used when molecules move from hypertonic region to hypotonic region (if ions) and hypotonic to hypertonic (if water). This is a passive transportation which do not require the expense of energy from the cell.
In contrast, when molecules move in or out of the cell against their concentration gradient, that is ions moving from hypotonic region to hypertonic region, they implore the expense of energy in form of adenosine triphosphate (ATP), and the involvement of the membrane carrier proteins. This is called active transport.
Answer:
<em>"Maturation refers to the child's increases in body size."</em>
Explanation:
The statement "Maturation refers to the child's increases in body size" does not tell anything about the state of the patient and it needs to give a clear explanation.
Growth can be described as the physical increase in size of a person.
Development can be described as the process by which children learn different skills as they grow up.
Maturity can be described as the growth in different body system which leads to the development of different skills in the children.
Answer:
The major organs of the nervous system are the brain, spinal cord, sensory organs, and all of the nerves that connect these organs together.
The nervous system reacts to the presence of danger(instinct), stores memories, control the 5 senses, and commands the rest of the organ systems to maintain homeostasis.
The nervous system works together with the respiratory system, the circulatory system, the muscular system, and many more.
