Answer:
The correct answer is "There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include: multiple receptors for the same hormone, a single receptor coupled to different pathways and hormones interacting with receptors for other molecules".
Explanation:
Hormones are among the most versatile molecules of the body, responsible for different biological processes such as human growth, sex development and metabolisms. Hormones are responsible of these complex biological processes because they have drastically different effects in different cells. There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include:
- Multiple receptors for the same hormone. For instance, there are multiple receptor for dopamine, a hormone and neurotransmitter responsible for different functions such as movement, memory, sleep and motivation.
- A single receptor coupled to different pathways. Most hormone receptors act with a cascade of signaling. This in consequence results in a single receptor interacting with different molecules having multiple effects.
- Hormones interacting with receptors for other molecules. One example is the action of one metabolite of progesterone named allopregnanolone. This metabolite interacts with GABA-A receptor, which gives it anxiolitic properties.
Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.

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.
