Basically, observation can be defined as the action or process of observing something or someone carefully or in order to gain information, in other words, watching or analyzing something so as to know more about it. For example, if a biologist wants to observe the behaviour of a specific kind of animal in the wild, that person will have to watch and focus on what that animal usually do, what it usually eats, how it hunts or find food, etc, in order to know more about the animal itself.
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

Answer:
oxygen
Explanation:
oxygen is an essential nutrient which the body needs especially during respiration.
it help the blood cells do provide energy.

There are different kinds of tides. This change occur because when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.
- This result above makes the high tides as been little higher and low tides been little lower than normal.
Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.
This often occurs when the moon, earth, and sun are said to be at a right-angled plane. Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.
