Ans.
The biodiversity of a coral reef ecosystem will be decrease if there is a decrease in coral reef population as most if the marine organisms, such as microbes, sea urchins, plankton, fishes, seahorses, along with larger animals, such as sea turtles, directly or indirectly depend on coral reefs. As seaweeds act as competitors of corals, overgrowth of seaweed population would decrease population of corals.
This will lead to a disturbance in coral reef ecosystem and decrease the ecosystem's biodiversity. Thus, the correct answer is 'option B). the overgrowth of seaweed would prevent light from reaching the reef.'

Conductive hearing loss is when sound cannot reach the inner ear.
Sensorineural hearing loss happens when the sound is not able to be processed correctly.
Gout is brought about deposition of solidified or crystallized uric acid sediments most commonly in the lower extremities brought about by increased levels of uric acid. An elderly patient (67 years old) previously diagnosed with gouty arthritis came in with a chief complaint of severe pain on the foot.
Gouty arthritis has 4 stages:
(1) Asymptomatic hyperuricemia
(2) Acute gout attack
(3) Intercritical gout
(4) Chronic tophaceous gout
Lower extremity examination of gout patients in in stages 2-3 will reveal edema, redness, and extreme of the involved foot. In stage 4 gout, along with edema, redness, and tenderness; there will be the presence of white to yellow deposits called tophus (plural; tophi) usually in the medial side of the big toe.
