Question #1: D
Question #2: B
These are the correct answers hopefully. I knew the second one, but the first one I had to look up and do a wee bit of research
<span>The correct answer is b. The open ocean. The definition of an island ecosystem does not have anything to do with water, but simply refers to an ecosystem that exists as a microcosm within a far larger, separate ecosystem. The ocean has lots of separate island ecosystems within it, but it itself cannot be referred to as one.</span>
The enzyme will work as a catalyst and make the chemical reaction happen quicker
Answer : The The correct option is, If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.
Explanation :
- Elastic collision : It is defined as in which there is no loss of kinetic energy in the collision.
- Inelastic collision : It is defined as in which there is a loss of kinetic energy in the collision and this energy changed to another form of energy.
If the collision involves bouncing, it is inelastic because kinetic energy is not conserved.
If the collision involves sticking together, it is inelastic because kinetic energy is not conserved, it is changes to potential energy.
<span>Dehydration synthesis involves substances combining together (synthesising) while at the same time losing water (dehydrating). The process of lipids turning into fatty acids involves dehydration synthesis.</span>
