DNA is made up of the individual units called Nucleotides.
the term used to describe how well an organism functions in its environment is variation
Answer:
ATP production.
Explanation:
The result will be the production of ATP molecules if we place thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. The thylakoids are able to formed ATP in the dark because H+ gradient is required for ATP synthesis. The scientists find out that the light reactions were not necessary to establish the H+ gradient required for ATP synthesis by ATP synthase.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
