Answer:
Sarah should add 19 grams of protein to her diet if she gets pregnant.
Explanation:
Daily protein requirements = body weight in x conversion factor
Pregnant women= 1.1g/kg prepregnancy body weight
Sarah's prepregnancy weight= 132 pound
Sarah should add about 19 grams of protein to her diet to account for the higher protein requirements of pregnancy. That’s only about 1 cup of Greek yogurt. Pregnancy might be the time to switch to these “twice the protein” products.
every cell in our body contains Dna
Well, we can rule out diffusion and osmosis because these are passive processes, so we're left with A and C. I'd say A, because the energy is used in muscle contraction.
Answer:
Each cell has a unique chemical composition
Explanation:
All the other answers are apart of the modern cell theory.
Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
