Answer:
Option B, blocking alpha-1 receptors found in smooth muscle in the bladder neck and prostrate, causing them to relax
Explanation:
The subtype alpha (1A) of alpha (1) adrenoceptors are mainly responsible for expressing and contracting bladder neck, urethra and prostate thereby enhancing bladder outlet particularly in elder men (45 Years above) who have enlarged prostates.
If this alpha-1 andrenoceptors found in smooth muscle of bladder neck and prostrate are blocked somehow, then the muscles will relax and this how antiandrogens are used for treat ing benign prostatic hypertrophy
If these α1A subtype receptors are stimulated by norepinephrine, then smooth muscles are caused thereby producing a physical block at the bladder neck
Hence, option B is correct
The appropriate answer is EXCRETION. Excretion is the process by which metabolic waste products are eliminated from the body. Living things take in molecules from the environment and chemically change them into molecules that form their own structures, control their physiology and provide them with energy. Metabolism is the sum of these reactions. These reactions produce waste material that can be toxic to cells if they accumulate. Metabolism therefore requires the process of excretion.
It piles up and then it will ruin the economy
Answer: =<u>Convergent</u> evolution
