Answer:
The correct answer is (b) epinephrine.
Explanation:
Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.
In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.
When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

Answer:
Explanation:
Wave generators harness the power of breaking waves which are disturbances that transmits energy to produce electric power for homes and industries.
This energy source is choice by many because it is environmentally friendly.
Here are some of the disadvantages;
- Threats to marine ecosystem especially those organisms that resides on the continental shelf where most these generators are installed.
- It can pose serious damage to the beach natural outlook as energy waves can be periodically discharged.
- Disruption of ships and vessels that might dock near the beach.
- Noise pollution generated by the plant is undesirable.
- The seasonality of waves might cause fluctuations in power generation.
