Answer:
<em>The correct option is B) regulation of mitosis</em>
Explanation:
Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.
Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
Answer:
The incorrect statement is that the neural reflex arc becomes slow by the hormones involved.
Explanation:
A neural pathway that controls a reflex is known as a reflex arc. In a reflex arc, the sensory neuron transmits a signal to the interneuron and stimulates it. The interneuron then transmits or passes the signal to the next neuron, that is, a motor neuron. The motor neuron associates with the interneurons in the spinal cord, which transmits messages from the CNS to the body. Thus, a reflex arc comprises the elements, that is, the receptor, integrating center, and the effector. Their main activity is to protect the body from external events.
Answer:
The correct answer is option b. "by their dominant processes that formed them".
Explanation:
Mountains are classified in four different types according to the dominant processes that formed them. The four different types of mountains are: upwarped mountains, fault-block mountains, folded mountains and volcanic mountains. Upwarped mountains are produced by a differential of pressure from inside the Earth that pushed the crust upwards. Fault-block mountains were formed by tectonic plate movement, folded mountain when two plates move together, while volcanic mountains are formed by a crack in the Earth known as volcanic vent.
