The first terrestrial vertebrates evolved from
A
pisces
B
reptilia
C
amphibia
D
mammalian
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
- The earliest vertebrates resembled hagfish and lived more than 500 million years ago. As other classes of fish appeared, they evolved traits such as a complete vertebral column, jaws, and a bony endoskeleton. Amphibians were the first tetrapod vertebrates as well as the first vertebrates to live on land.

Solution
The part of alimentary system of a bird where food is ground into small particles is the?
A
cloaca
B
stomach
C
crop
D
gizzard
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
The gizzard is the mechanical stomach of a bird. It is located just after the true or glandular stomach in the gastrointestinal system. Since poultry have no teeth and swallow feed whole, this muscular organ, sometimes called hen's teeth, mechanically grinds and mixes the bird's feed.

Respiration & Gaseous Exchange
Solution
The enzymes of the glycolytic pathway are located in the?
A
mitochondria
B
gastric juice
C
plasma
D
cytoplasm
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Glycolysis is a metabolic pathway that does not require oxygen for the breakdown of glucose into pyruvate or pyruvic acid by enzymes in the cytoplasm of the cell.
Then the NADH + H+ generated by glycolysis has to be transferred to the mitochondrion to be oxidized, and thus to regenerate the NAD+ necessary for glycolysis to continue.
