Answer:
I'm not sure if it's true or false, but what I'm sure about is there is chemical energy IN food.
Explanation:
In short, food contains chemical energy
Answer:
The height of a dam:
h = x + 1.65 m,
x = 90 m · tan 26°
x = 90 · 0.4877
x = 43.90
h = 43.90 m + 1.65 m = 45.55 m
The height of the dam is 45.5 m.
Explanation:
In a nutshell:
- Chemical reactions love stability.
- Usually if heat is given off, the chemicals are happier as they are more stable.
- This should happen naturally, like a ball rolling down a hill.
- But if you <em>force </em>chemicals to do things that make them more <em>unstable, </em>you're going to have to put energy in.
- Like forcing a ball up a hill, it isn't naturally going to roll up without you putting in energy.
- "exo-" means "away from" and "endo-" means "within". Think about this in terms of heat, or energy.
- heat released -> exothermic reaction (energy escapes)
- heat put in -> endothermic reaction (energy is put within)
Also the word "enthalpy" and ΔH is used a lot to relate to energy.
A negative ΔH means heat loss and a positive ΔH means heat put in as well.

Answer is : C, increase the surface to allow more space for ATP synthesis.
As it produces large amounts of ATP through oxidative metabolism of pyruvates, which are produced by glycolysis.
The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.
Each cell contains a different number of mitochondria The number present is dependent upon how much energy the cell requires. The more energy a cell needs the more mitochondria that will be present. Cells have the ability to produce more mitochondria as needed. They also can combine mitochondria to make larger ones.
The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism.The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle. However, the mitochondrion has many other functions in addition to the production of ATP.
Ozone filters the UV radiation (emitting by Sun). By doing that, it keeps our environment safe & healthy.
