Simora [160]3 years ago

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.

<h3><u>Explanation:</u></h3>

When an underwater earthquake has just been recorded in the middle of the Pacific Ocean, the seismologists will be called to determine if the effects of this earthquake and whether or not it will cause tsunamis off the coast of Hawaii.

Seismology is the study of earthquakes, the escalation of waves and the effects they might have. A seismologist is a scientist who is concerned with these studies. They make use of seismographs and other relevant tools to gather essential data which helps in reading the planetary movements and understanding them better. The study does not always predict an earthquake but it helps in predicting the possibility of tsunamis. Seismology enabled the development of tsunami warning systems.
