Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !
random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !
and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !
Answer: Adrenergic drugs are used both in the emergency treatment of Myocardial infarction, Asthma attack and Anaphylaxis T/F.
Explanation:
Andrenergic drugs acts by blocking renin release,and interfers with synthesis and release of Nor-epinephrine (Nor-adrenaline) thereby helping to reduce the peripheral vascular resistance and lowering the blood pressure.example; Methyldopa.
As a bronchodilator in asthma attack, Adrenergic drugs relax bronchial muscle spasm then dilate the bronchial trees thereby allowing proper ventilation of the lungs example: Aminophylline
Adrenergic drugs like epinephrine are used in anaphylaxis/ allergic reactions as well as hypersensitivity reactions to inhibit the action of histamines and as such relieve allergic reactions.
<span>The answer would be: requires an outside energy source for a nonspontaneous chemical reaction to occur

An electrolytic cell is a cell that could change electric energy into chemical energy. It uses electric to induce a nonspontaneous chemical reaction.
