Solution
In a population study using the transect method, a student is likely to record the highest number of species in?
A
a tropical rain forest
B
a guinea savanna
C
a sahel savanna
D
an estuarine swamp
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
A student using the transect method is most likely to record the highest number of species in a tropical rainforest because it has the highest biodiversity of all the listed ecosystems. While other ecosystems like the guinea savanna are diverse, tropical rainforests are recognized as the most biologically rich ecosystems on Earth.

Digestive System & Feeding Mechanisms
Solution
The carnassial teeth of a carnivorous animal consist of the
A
last upper premolar and the first lower molar
B
last upper molar and the last lower molar
C
first upper premolar and the lower molar
D
first upper molar and the first lower molar
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The carnassial teeth of a carnivorous animal are made up of the fourth upper premolar and the first lower molar.
The carnassial teeth work like scissors to slice through meat, tendons, and muscles.The sharp cusps of the carnassial teeth are able to slice through meat because the inside of the fourth upper premolar closely passes by the outer surface of the first lower molar.
