Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Explanation:
I would say that Melissa has made the mistake of using the same uncleaned cutting board first for cutting up chicken which is notorious for forming bacteria quickly when out of the fridge and then chopping vegetables on it thus running the possibility of contaminating the vegetables with chicken bacteria. She should ensure she washes the cutting board carefully with soap and water to avoid contamination of the vegetables.
Atoms are like a blueprint, they make up things, they can make up water as in H2O, nutrients and chemical compounds. These are things that make up a living organism. and atoms make up everything and the fact that they can create something that is living is beyond comprehension if not we would be able to create living things from nonliving things
Answer:
law of superposition
Explanation:
The law of superposition in geology suggests that the sediments are spreading out in a horizontal manner, flat, in all directions, until there's some natural feature that will stop them. It also suggests that the sediments are arranged vertically from the oldest being at the bottom, and the youngest layers being on the top.
Even though this is not always the case in nature, still there are lot of examples that support the law of superposition. When the sediments are aligned in that manner, the geologists find it very helpful and easy to determine the relative age of the layers, as well as the relative age of the fossils that are found in them.
