Question

The mitochondrial inner membrane carries out the same function in cellular respiration as the membrane of chloroplasts in photosynthesis. Which of the following correctly completes the sentence above?

Answer 1

Correct Answers:

thylakoid

Rationale :

🎯The mitochondrial inner membrane is the site of the electron transport chain in cellular respiration. The thylakoid membrane in chloroplasts is the site of the light-dependent reactions (which also include an electron transport chain) in photosynthesis.

Answer 2

Correct Answers:

Heart and lungs

Rationale :

✒The thoracic cavity houses the heart and lungs, making them the most vulnerable to blunt trauma in this area.

Answer 3

Correct Answers:

Insulation

Rationale :

🔍The myelin sheath surrounds the axon of a nerve cell and functions as insulation, allowing faster transmission of electrical impulses along the neuron.

Answer 4

Correct Answers:

B

Rationale :

🎯Curve B levels off after a period of growth, indicating that the population size has stabilized. This pattern is characteristic of a population reaching its carrying capacity, where the birth rate equals the death rate and resources are limited but sufficient to support the population.

Answer 5

Correct Answers:

Diastole

Rationale :

✔Diastole refers to the phase in the cardiac cycle when the heart muscles relax, allowing the chambers to fill with blood.

Answer 6

Correct Answers:

100,000

Rationale :

🎯The pH scale is logarithmic, meaning each unit change represents a 10× difference in hydrogen-ion concentration.

Difference between pH 9 and pH 4 = 5 units
Therefore, hydrogen-ion concentration is:

♦10⁵=100,000 times stronger

Answer 7

Correct Answers:

germ

Rationale :

🧬Germ cells (egg or sperm) are involved in reproduction and pass genetic material to offspring.

Somatic cells, white blood cells, and stem cells do not directly pass mutations to offspring.

Answer 8

Correct Answers:

Small Intestine

Rationale :

💡Small intestine→Major site for digestion and absorption.

Esophagus: Only transports food — no digestion or absorption.
Stomach: Primarily digestion, minimal absorption.
Gallbladder: Stores bile — no digestion or absorption
