Answer:
The similarities in the way barchan and hooked spit forms are:
First, they are formed from sediment or sand movement.
Second, this movement makes them have a peculiar curved form that provides them their major characteristic.
Explanation:
First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.
Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
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.
