20 questions
Question 1: The impulses generated by the maculae are primarily sent to the cerebrum for interpretation of balance.
A. Ano
B. Ne
Explanation: The study materials state that the impulses generated from the maculae are sent to the cerebellum, not the cerebrum, to restore balance.
Question 2: Based on the provided study materials, which of the following statements about deafness, its causes, or treatments are correct?
A. Deafness can be caused by the hardening of ear tissues, such as the ossicles.
B. Cochlear implants function by transmitting sound vibrations directly to the auditory nerve as an electrical impulse.
C. Injury to the tympanic membrane is the only cause of total hearing loss.
D. Hearing aids are a treatment for deafness that receive, transmit, and amplify sound vibrations.
Explanation: The study materials state that deafness 'may be caused by: hardening of ear tissues such as the ossicles.' Therefore, option 0 is correct. It also explains that a 'cochlear implant receives sound vibrations and converts them into an electrical impulse which is transmitted directly to the auditory nerve,' making option 1 correct. Furthermore, it states that a 'hearing aid receives, transmits and amplifies sound vibrations,' making option 3 correct. Option 2 is incorrect because the materials list 'injury to parts of the ear, nerves or parts of the brain responsible for hearing' as a cause, not solely injury to the tympanic membrane, and deafness can be partial or total, not exclusively total.
Question 3: Auxins produced at the tip of the stem promote the growth of lateral branches closer to the tip.
A. Ano
B. Ne
Explanation: Auxins produced at the tip of the stem move downward and inhibit the growth of the lateral branches closer to the tip of the stem. This process is called apical dominance.
Question 4: Which of the following describes a chemical defense mechanism employed by plants, according to the provided study materials?
A. The production of auxins to inhibit the growth of lateral branches.
B. The bending of stems towards a light stimulus through phototropism.
C. The growth movement of roots downwards in response to gravity.
D. The study materials do not provide information on specific chemical defense mechanisms.
Explanation: The study materials mention 'Chemical defences' as a sub-topic under 'Plant defence mechanism' on page 236. However, no specific details, examples, or descriptions of chemical defense mechanisms are provided within the given text. The text proceeds to discuss plant hormones like auxins, tropisms, and experimental procedures, but not the nature of chemical plant defenses.
Question 5: Abscisic acid is the plant hormone that promotes seed dormancy.
A. Ano
B. Ne
Explanation: According to question 1.1.3, which asks 'Which plant hormone promotes seed dormancy?', option C 'Abscisic acid' is the correct answer. Additionally, question 1.2.8 defines 'The plant hormone that promotes seed dormancy' as Abscisic acid.
