What does the term electron orbital describe?An electron orbital describes the orbit of an electron around the nucleus.An electr
AlekseyPX

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".

The step at which the researchers would do at the end of researching Edna is to amplify the amount of DNA.

Option (d);

<u>EXPLANATION:</u>

  • The term EDNA means Environmental DNA.
  • Invasive species in the waterway are the waterborne plants and animals who can likely cause effects to the human as well as the environment.
  • If researchers want to use eDNA to look for invasive species in the waterway, they will first collect a sample.
  • After cutting DNA into pieces, DNA would be precipitated in each sample.
  • And in the end, the amount of DNA would be amplified in each sample to understand how it would cause harm to the environment.
