Answer:
Courtney is looking at Prokaryotic Cell.
Explanation:
Ok, when Courtney is observing the science experiment, and finds a cell that includes DNA and has a nucleoid region but does not have nucleus, it is a prokaryotic cell and only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes, where pro means before and kary means nucleus.
Let's explain what is a prokaryotic cell: prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. And most prokaryotes have a cell wall outside the plasma membrane.
Answer:
The similarities that can be seen in the members of kingdom plantae and plankton is that both of them perform photosynthesis.
These organisms provide oxygen and food to the other members. These members get energy for living their life.
The planktons and the members of kingdom plantae requires nutrients for their growth and development.
The differences that can be seen in the plankton and members of plantae is that plankton are found on the surface of water.
The members of plantae can be found on the land, on the surface of water. But some of the species like brown and red algae are found in the depth of sea or ocean.
I believe that if kinetic energy were to decrease, then the speed would decrease because the more kinetic energy an object has, the more speed an object has.

D.-
Explanation:
A control group is needed to carry out the experiment, that control group is the one that is not injected with anything. Ethanol and pesticide need to be injected into separated groups to document whether it is one or the other that is harmful
