Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves
jarptica [38.1K]

Answer:

The correct option is;

Water absorbing energy in large amounts to increase energy by a degree of temperature

Explanation:

The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls

Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose

The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds

The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.

NEED HELP ASSAAPP!!!! 2. What protein changes shape in sickle cell anemia? What are two effects of this change?
mixer [17]

Answer:

Hemoglobin

Explanation:

Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.

The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.

The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.
