Answer:
The muscle has two, three, or four origins, respectively.
Explanation
- A muscle is an organ composed of muscle tissue that contract to facilitate a particular movement
- biceps,triceps and quadriceps are types of skeletal muscles since they use bones as levers
- <em><u>They differ in that; the biceps have two origins, triceps have three origins and quadriceps have four origin.</u></em>
- <em><u>Bicep is a two headed muscle thus said to have two origins ,triceps have three muscle heads and therefore have three separate origin attachment point while quadriceps are made of four muscles heads hence have four origins. </u></em>

Answer: A) They are the site of protein synthesis.
Explanation:
Ribosomes are small round organelles attached to the endoplasmic reticulum in cells, and serve as site of protein synthesis. This is possible because the transfer RNA assembles amino acids to form polypeptide chains right in the ribosomes.
Thus, ribosomes are site of protein synthesis
Answer:
Option (D)
Explanation:
The tropical rain forest and tropical dry forest lies on the tropical regions of both the hemisphere. These are the regions on and around the tropic of cancer and tropic of capricorn. In the tropical rain forest, the rate of precipitation is higher than the rate of evapo-transpiration, so the temperature remains relatively cooler. Whereas, in the tropical dry forest, the rate of evapo-transpiration is more than the rate of precipitation, as a result of which the temperature remains comparatively high.
The tropical dry forest is very good for agricultural purpose, as it contains nutrient rich soil. So it has been destroyed to a greater extent for agricultural use, grazing of animals.
Whereas, the tropical rain forest is not suitable for the agricultural use because the soil here are affected by the rainfall, that washes away the nutrients, making the soil less fertile.
Thus the correct answer is option (D).
