Answer: Option C
Explanation:
The amitochondriate eukaryotes may have genes that have been derived from purple alphaloproteobacteria because they do not have the mitochondria which is needed to optimize energy production in the presence of oxygen, can live and exist in a condition with little to no oxygen which is a characteristic of proteobacteria and hence are anaerobes obtaining energy by anaerobic respiration. They may have also undergone the endosymbiont theory but due to their environment which has little to no oxygen. They do not have a need for the mitochondria organelle and in the process lose this organelle.
The result which would be seen from a properly prepared negative control is nothing.
<h3>What is a Negative control?</h3>
This type of control is used to test and ensure that in the absence of the antigen we do not still get a positive reaction.
Since proper aseptic technique was practised and there was no swabbing of the surface then there would be nothing seen in the properly prepared negative control.

Answer: Interphase; Prophase; Metaphase; Anaphase; Telophase
Explanation:
1) The genetic material is duplicated (Interphase)
2) Chromosomes become visible the spindle apparatus forms (Prophase)
3) The chromosomes line up in the middle of the cell. (Metaphase)
4) The cell plate forms; the nuclear envelope is formed. (Anaphase)
5) Chromosomes move to opposite ends of the cell (Telophase)
Answer:
Viruses are not living things. One reason viruses are not alive is because they require a host to survive and reproduce. A second reason a virus is not alive is because they do not stimuli. A final reason that a virus is not alive is that they are not made up of cells. All living things can reproduce without a host, are made up of cells and react to stimuli except viruses, so they are not living.
Answer: 1. we wouldn’t be able to tilt so no day and night therefore lack of sun and night causing the earth to overheat and be too cold at some point which could kill the whole population.
2. The earth would just float around, we wouldn’t have track of time, and we could float towards the sun or too far away
