Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the process of diffusion in which ion or some substances are transported across the membrane by a specific carrier membrane protein. The process does not require the input of energy and is driven by a concentration gradient.
The absorption of simple sugars in small intestine occurs through facilitated diffusion. The polar sugar molecules can not cross the nonpolar inner core of the membrane. Hence, the membrane proteins transport the sugars down the concentration gradients without any input of energy.
Answer:
C
Explanation:
A, B, and D are done by other things, but acid can also be used to get rid of unneeded/wanted bacteria or organisms.
There are choices for this question namely:
Carvedilol
Betaxolol
Acebutolol
Propranolol
Metoprolol
The correct answers are "betaxolol", "acebutolol",and "metoprolol". These drugs are from the class called beta blockers as they inhibition the action of beta receptors in the heart leading to a decrease in heart rate and blood pressure. There are also beta receptors in the bronchial tree, an inhibition of which will lead to bronchoconstriction.
Betaxolol, acebutolol, and metoprolol are cardioselective beta blockers and only blocks the beta receptors located in the heart. Carvedilol and propranolol are non-selective beta blockers that can cause bronchoconstriction which is contraindicated in patients with asthma.
Answer:
B
Explanation:
The more the soil absorbs water the less space there is for the soil to absorb more therefore it runs off.
