Which of the following is true about ischemic stroke? a. Often caused by emboli from the basilar arteries b. Has risk factors that include atherosclerosis c. Can be a result of a hypercoagulable state d. Results from hemorrhage into brain tissue Is associated with acute hypertension

b. Has risk factors that include atherosclerosis

Explanation:

Ischemic stroke happens when there are underlying factors such as atherosclerosis. Atherosclerosis is caused by clogging of fat and cholesterol in the blood vessels. The reduction in the flow of blood to the brain is usually as a result of blood clumping together and blocking the blood vessels carrying blood to the brain.

The symptoms of ischemic stroke include dizziness, loss of coordination, headache etc.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
