Answer:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Answer: c
Explanation:
This stored form of glucose is made up of many connected glucose molecules and is called glycogen
Because water goes through your systems and makes you survive. They can live with water forever.
Correct answer: A) Extension
Extension is a physical position that occurs when angle between the bones and the limbs of joint increases.
It takes place when there is a contraction of muscles and bones move the joint from a bent to a straight position, it is opposite of flexion, in which the angle between the bones and the limb at the joint decreases.
Example: During straightening of the leg, the angle between the tibia and femur increases, which shows extension has taken place.
Answer:
The principle of conservation of energy states that in a closed system, the total amount of energy:
A.remains the same
Explanation:
The principle of conservation of energy says that in a closed system, energy can not be created or destroyed, but it can change form. For a closed system no mass can leave or enter in the system, for this reason there is no energy transfer and for this reason the total amount of energy doesn't change and remains the same in the system.
