Excretion & Homeostasis
Solution
A fundamental similarity between nervous and hormonal system is that both
A
involve chemical transmission
B
have widespread effects
C
shed chemicals into the blood stream
D
evoke rapid responses
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The fundamental similarity between the nervous and hormonal systems is that they both use chemical signals to communicate and coordinate bodily functions. The nervous system uses neurotransmitters to transmit signals rapidly through nerve impulses, while the hormonal system uses hormones to transmit slower, more general signals throughout the body via the bloodstream. Both systems contribute to maintaining homeostasis and regulating various physiological processes.
Chemical transmission is a fundamental similarity between the nervous and hormonal systems. Both systems utilize chemicals to transmit signals, but they differ in the type of chemical and the method of transmission.

Variation & Genetics (Heredity)
Solution
Which of the following is a sex-linked character?
A
Sickle-cell anaemia
B
Tongue rollling
C
Skin colour
D
Colour blindness
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Colour blindness is a sex-linked character, specifically an X-linked recessive trait, meaning the genes responsible for it are located on the X chromosome.
Colour blindness is caused by genes on the X chromosome, and because males only have one X chromosome (XY), a single copy of the recessive gene can cause the condition.

Adaptation & Evolution
Solution
A physiological adaptation of plants to the problem of excessive water loss is
A
reduction in the number of stomata
B
reversal of the normal stomatal rhythm
C
possession of shallow roots
D
possession of waxy cuticles
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
To combat excessive water loss, plants employ physiological adaptations like stomatal closure, reduced leaf surface area, and waxy cuticles, along with strategies like leaf shedding and root proliferation to conserve water.
Stomatal closure, and specifically its reversal, is a crucial physiological adaptation that plants use to conserve water and prevent excessive water loss, particularly during drought or other water-stressed conditions.

Solution
which of the ways of controlling bilharzia can result in pollution?
A
clearing water weeds on which the snail feed
B
Treating infected people with drugs
C
Preventing contamination of water by infected urine and faeces
D
Applying chemical to kill the snails
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Bilharzia which is also known as Schistosomiasis is a disease caused by a parasite that develops in snails, lives in water and enters humans through your skin. Applying chemicals to ill the snails in the bid to control bilharzia will lead to air pollution because the snails would die and would begin to have offensive smell. However, option D is the correct answer.
