<span>The female frog's reproductive system is consist of a pair of ovaries and a pair of oviducts. The ovaries are attached to the kidneys. The kidneys carry countless ova which are released to outside through the oviducts. </span><span>In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.</span>
number 1 is not part of the theory of evolution.
Evolution is change in the heritable characteristics of biological populations over successive generations.
Answer:
4. Warm air from the inside moving toward the cold air outside.
Explanation:
A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.
This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.
Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.
<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>
