Answer: When we regularly eat more kilo joules than our body needs, the spare energy is stored as fat. Eating as little as 100kJ extra each day (or burning 100kJ less by exercise), can lead to one kilogram of body fat creeping on over a single year.
Explanation:
Sugar and it’s because they are very similar
D because they are complete systems
Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water.
Answer: Option A & D
<u>Explanation:</u>
A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.
When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
Answer:
because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time.Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly
