Gregor Mendel is known as the 'father of genetics' for his experiments on:
A. Pea plants (Pisum sativum)
B. Fruit flies (Drosophila)
C. Snapdragons (Antirrhinum)
D. Four o'clock plants (Mirabilis)
Answer: Option A
Solution (By JKExamLibrary)
Gregor Mendel, an Austrian monk, is known as the 'father of genetics' for his pioneering experiments on inheritance in the garden pea plant (Pisum sativum) between 1856 and 1863. He studied seven pairs of contrasting traits and formulated the fundamental laws of inheritance: the Law of Segregation and the Law of Independent Assortment, which form the basis of classical genetics.

Question #1
Which part of the human kidney filters blood under high pressure?
A. Collecting duct
B. Glomerulus
C. Loop of Henle
D. Renal pelvis

Correct Answer: Option B


Explanation:
The glomerulus is a tuft of capillaries enclosed by the Bowman's capsule, where ultrafiltration occurs due to high hydrostatic pressure in the afferent arteriole. It filters water, ions, glucose, amino acids, urea into Bowman's space. Proteins and cells are retained. Filtration is passive. The filtrate then passes through the tubules for processing. GFR is regulated by JGA.

Question #2
The symbiotic relationship where one organism benefits and the other is unaffected is:
A. Mutualism
B. Predation
C. Commensalism
D. Parasitism

Correct Answer: Option C


Explanation:
Commensalism (+/0) involves one species benefiting and the other neither harmed nor helped. Example: barnacles on a whale, or cattle egrets eating insects stirred by cattle. Mutualism benefits both (+/+), parasitism benefits one at expense of other (+/-), predation (+/-) involves killing. The distinction is based on the net effect.

Question #3
The organ that produces the hormone erythropoietin is the:
A. Kidney
B. Liver
C. Bone marrow
D. Spleen

Correct Answer: Option A


Explanation:
The kidneys sense low oxygen levels and secrete erythropoietin (EPO), which stimulates red blood cell production in the bone marrow. The liver also produces some EPO in fetal life. Bone marrow is the target, not producer.
