Answer:
mutations in proto-oncogene are generally cancerous while mutation in tumor-suppressor alleles are recessive and result lost of function
Answer:
C
Explanation:
The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.
The correct answer is option B, that is, the sympathetic system prepares the body for stress and activity and the parasympathetic system prepares the body for rest.
Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system that works obligatorily. The sympathetic nervous system holds the key in controlling the body at the time of stress and injury, it is generally regarded as fight or flight. It contracts the muscles of the heart in order to enhance the rate of the heart.
On the other hand, the parasympathetic nervous system is responsible to monitor the function of the body when it is at rest. It assists in sustaining the homeostasis in the body. It relaxes the muscles of the heart in order to reduce the rate of the heart.
Answer:
it will result in reduced genetic diversity within the spedes
