The Oxygen-Carbon Dioxide Cycle. Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. ... Animals breathe in the oxygen made by plants and breathe out carbon dioxide as a waste product.
C. during the same time span and from the same material as the sun
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.
DNA is able to control cellular activities most directly by regulating the process of Protein synthesis.
An action potential is the variation of the electrical potential associated with the passage of a pulse along the membrane of a muscle cell or a nerve cell.
<h3>What is a nerve cell?</h3>
The nerve cells are the cells involved in the formation of nervous tissue. it helps in the conduction of stimuli through the nervous system.
An action potential is the variation of the electrical potential associated with the passage of a pulse along the membrane of a muscle cell or a nerve cell.
Thus, the answer is action potential.
