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.
The mean rate of photosynthesis when the carbon dioxide concentration was 0.2% is 8 .
<h3>What is photosynthesis?</h3>
The process of photosynthesis is defined as the green plants prepare there own food in the presence of sunlight and during this process heat energy is converted into chemical energy is known as photosynthesis. The process is takes place only in green plants as they contain chlorophyll.
The plant use water, carbon dioxide, nitrogen in the form of nitrates, sunlight and sugar as the source of energy to prepare its own food. Plants prepare there own food so they are known as autotrophs.
Therefore, The mean rate of photosynthesis when the carbon dioxide concentration was 0.2% is 8 .
