Consider statements about human physiology: 1. The hypothalamus regulates body temperature. 2. The cerebellum controls voluntary muscle coordination. 3. The medulla controls reflex actions like swallowing. Which are correct? MCQ with Answer and Explanation

Consider statements about human physiology: 1. The hypothalamus regulates body temperature. 2. The cerebellum controls voluntary muscle coordination. 3. The medulla controls reflex actions like swallowing. Which are correct?
A. 1 and 3 only
B. 2 and 3 only
C. 1, 2 and 3
D. 1 and 2 only
Answer: Option C
Solution (By JKSSB Mock Tests)
The hypothalamus is the primary thermoregulatory center, maintaining body temperature through sweating or shivering. The cerebellum coordinates voluntary movements, ensuring smooth and accurate muscle activity and balance. The medulla oblongata contains vital reflex centers controlling involuntary actions such as swallowing, coughing, sneezing, and vomiting. All three statements are anatomically and physiologically correct.

Question #1
The organ of the human body that stores glycogen as a reserve carbohydrate is:
A. Liver
B. Spleen
C. Pancreas
D. Kidney

Correct Answer: Option A


Explanation:
The liver is the primary site of glycogen storage and releases glucose into the blood between meals (glycogenolysis) to maintain blood sugar. Muscles also store glycogen but for local use. The pancreas regulates blood sugar via insulin/glucagon, spleen stores blood and recycles iron, kidneys excrete waste.

Question #2
The stage of human embryonic development in which the embryo implants in the uterine wall is the:
A. Blastocyst
B. Zygote
C. Morula
D. Gastrula

Correct Answer: Option A


Explanation:
The blastocyst, a hollow ball of cells with an inner cell mass, hatches from the zona pellucida and implants into the endometrium around day 6-7 after fertilization. The zygote is the fertilized egg, morula is a solid ball, gastrula forms the three germ layers post-implantation.

Question #3
Consider statements about microorganisms: 1. Algae are photosynthetic. 2. Protozoa are multicellular. 3. Fungi reproduce by spores. Which are correct?
A. 1 and 3 only
B. 2 and 3 only
C. 1, 2 and 3
D. 1 and 2 only

Correct Answer: Option A


Explanation:
Algae are a diverse group of photosynthetic, eukaryotic organisms ranging from unicellular to multicellular forms. Protozoa are unicellular, heterotrophic eukaryotic organisms, not multicellular. Fungi typically reproduce asexually and sexually through the formation of spores, which are dispersed to form new individuals. Thus, statements 1 and 3 are correct.
