An energy pyyramid shows how the energy "flows" from organism to organism as it goes up.
Answer:
1. import and export of nutrients and wastes
2. cell signaling
3. cell recognition
4. cell growth and motility
Explanation:
Plasma membranes are selectively permeable which means it only allows selective molecules to cross through it. So the plasma membrane helps in the import and export of nutrients by simple diffusion, facilitated diffusion or through active transport.
There are membrane protein embedded in the plasma membrane which have different role. Some help in cell signaling like GPCR, some help in cell recognition and some act and transporter proteins.
The plasma membrane is also responsible for cell growth and motility because it allow the raw materials and signals to pass through it which is required by the cell to metabolize and grow. So 1,2,3,4 is the correct answer.
Answer:
One - third.
Explanation:
The children and adults must be protected from the malnutrition and each individual has the right to attain the minimum nutrient requirement. Different programs run in U.S.A. to fulfill the nutrient deficiency.
RDA (Recommended Dietary Allowance) is a type of allowance given to the individual for the average daily intake to meet the nutrient requirement. Adequate Intake (AI) is provided when the individual do not have proper proves to develop RDA. The home delivered meals provide atleast one-third of the RDA.
Thus, the answer is one-third.
