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 is Change in cognitive function.
Reason. confusion, hallucinations, agitation, dizziness, falls and poor motor skills are often mistaken for early stages of dementia, but all can be caused by a UTI.
The correct option is the first one "Codominance", since both alleles are expressing at the same time.
Answer:
Option C.
Ocean acidification is the main ecological problem due to mariculture.
Explanation:
- Mariculture also known as the aquaculture that stands for the fish farming occupation.
- The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
- Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
- A build up of organic material beneath fish farms impacts the flora and fauna of an area.
- That makes drastic changes on sediment chemistry.
