Answer:
I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2
Explanation:
My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.
My glucose molecules were broken down into pyruvate, and I stayed that way for a while, as I made my way to the mitochondria of the child's cells. Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.
If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.
Glucose is converted into ATP because it is usable energy. Glucose is stored energy
Answer:
3. shapes the genetic characteristics of a species as a consequence of adaptation
Explanation:
Natural selection is a process characterized by how plants and animals that are able to adapt to changes in their environment are able to survive and reproduce while those that are unable to adapt do not survive.
In natural selection, those variations in the genotype which increases an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations.
Natural selection is a way of enhancing the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.
