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.
Answer:
D.
Explanation:
I think it may be point because only one section is changing.
Answer:
The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.
The correct way to paraphrase is 2. Every organism must acquire and use energy to build new structures, repair old ones, and reproduce
Explanation:
That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
