Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
an organelle that releases energy for metabolic activity in a nerve cell is the what
the mitochondria
The revolution of earth around the sun and the tilt of earth’s axis cause the changing of seasons. TRUE
<u>Explanation:</u>
Earth is slightly tilted at its axis. This causes a change in the amount of sunlight reaching each hemisphere. Due to the tilt one hemisphere will be closer to the sun while the other will be at a greater distance. When the earth revolves around the sun , the hemisphere that is closer to the sun changes.
The hemisphere closer to the sun will experience summer and the hemisphere away from the sun will experience winter.
Answer:
D. contact metamorphism
Explanation:
When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.
