Which of the following is an advantage of seed dispersal? MCQ with Answer and Explanation

Which of the following is an advantage of seed dispersal?
A. Reduces genetic diversity
B. Increases soil erosion
C. Avoids overcrowding and competition with parent plant
D. Competition between offspring
Answer: Option C
Solution (By JKExamLibrary)
Seed dispersal spreads seeds away from the parent plant, reducing competition for light, water, nutrients, and space. It also aids in colonization of new habitats and increases species distribution. Dispersal agents include wind, water, animals, and explosive mechanisms. Overcrowding would lead to resource limitation. Genetic diversity is promoted by cross-pollination, not directly by dispersal.

Question #1
Beriberi is a disease caused by the deficiency of:
A. Vitamin B2 (Riboflavin)
B. Vitamin B3 (Niacin)
C. Vitamin B6 (Pyridoxine)
D. Vitamin B1 (Thiamine)

Correct Answer: Option D


Explanation:
Beriberi is caused by a severe deficiency of Vitamin B1 (Thiamine). It affects the cardiovascular system (wet beriberi, causing edema and heart failure) and the nervous system (dry beriberi, causing muscle wasting and nerve damage). It is common in populations whose staple diet is polished rice, as the thiamine-rich husk is removed during polishing.

Question #3
The structure that connects the bones and allows movement is:
A. Joint
B. Cartilage
C. Ligament
D. Tendon

Correct Answer: Option A


Explanation:
A joint (articulation) is where two or more bones meet, allowing varying degrees of movement. Tendons connect muscle to bone, ligaments bone to bone, cartilage cushions. Joints are classified as fibrous, cartilaginous, or synovial.
