Gel electrophoresis separates DNA,RNA, and proteins. DNA fragments are separeted by their size, and proteins are separated by their size and charge (different proteins have different charges).
Well, the correct response would be C. Because the other 2 options are not really testable as they refer to plants having fish meal, or simply the fact that fish meal is better will be more beneficial to the plant and or will not hire
The correct option is A.
An infection disease is a type of disease which a person can acquire as a result of contact with the person who has the disease or as a result of contact with body fluids from that person. Infectious disease can be spread through increased virulence, increased incidence and different portals of entry. A decreased transmissibility reduces the probability of an infectious organism been transmitted.

What kind of organisms existed in the past?
How did organisms move about? are some testable questions hat could be used to further investigate the topic of using the fossil record to identify changes in life on earth.
- Fossils are the remains of extinct plants and animals that have been encased in layers of rock.
- The existence of fossil records demonstrates how living things have altered or evolved over time.
- The specific order in which these species have lived has been identified by paleontologists. For instance, older rocks contained simpler species, while younger rocks contained complex life.
- Existence of species with transitional traits that are placed in sequential stratigraphic order is one pattern in the fossil record.
- This indicates that the fossil record demonstrates minute changes in the structures of creatures across time, supporting evolution.
