Supporting Tissues & Skeletal System
Solution
The joint between the atlas and axis vertebrae allows for
A
rotatory movement only
B
up and down or nodding movements only
C
rotatory and nodding movements
D
no movement at all
E
slight movement
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
-The joint between the atlas and axis vertebrae is a PIVOT JOINT.
-The Odontoid Process of the axis acts as a pivot which allow the rotation of the head on the vertebral column.
-Hence; the atlas and the skull together ROTATE about the Odontoid Process.

Reproduction in Plants & Animals
Solution
For pollination and fruit formation, the essential part(s) of the flower should be the
A
corolla
B
ovary
C
pistil (gynoecium)
D
ovules
E
receptacle
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
The pistil is a highly essential part of a flower, particularly for pollination and fruit formation. It's the female reproductive part of the flower, and its stigma receives pollen, initiating the fertilization process that leads to seed development within the ovary, which then matures into a fruit.

Nutrition in Plants & Animals (Photosynthesis & Food Substances)
Solution
A green plant growing in a compost pit is feeding?
A
holozoically
B
parasitically
C
saprophytically
D
holophytically
E
in none of the above ways
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed organic matter.
Holozoic nutrition is a heterotrophic mode of nutrition that involves consuming other organisms, while holophytic nutrition is an autotrophic mode of nutrition that involves making food through photosynthesis. Green plants possess Chlorophyll which enables them manufacture their own food through the process of photosynthesis, regardless of where they are growing.However, the compost pit is just to supply the green plant with other nutrients that might be needed for growth.This mode of nutrition is also known as holophytic mode of nutrition.

Excretion & Homeostasis
Solution
During excretion of urea there is also a corresponding re-absorption of water into the blood. This re-absorption takes place in the
A
uriniferous tubules
B
Bowman's capsule
C
glomerulus
D
malpighian capsule
E
renal artery
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The uriniferous tubules refer to each of the long, fine, convoluted tubules conveying urine from the glomeruli to the renal pelvis in the vertebrate kidney. Water and salts are reabsorbed into the blood along their length.
