Answer:
Hypothesis is ''With the increase of algae in the aquarium, fish population decreases''.
Explanation:
The main problem was that there is no need for 2 aquarium because there is no need for aquarium 1 which has no fish and aquarium 2 which has fishes but no algae. With the increase of algae in the aquarium, fish population decreases is the hypothesis for this experiment. Concentration of algae is the independent variable of the experiment because there is no effect on it in the experiment.

Answer:
The answer is letter a, chemical evolution.
Explanation:
Chemical Evolution <u>is one of the processes that helps explain the origin of life. It states that the first living cell on earth started from non-living matters that were not capable of reproducing.</u>
This <em>non-living matter </em>could be both <em>organic and inorganic molecules.</em> It is said that the structures of these molecules changed over time (example is protein breaking down when exposed to too much heat). When these systems become complex, they form new structures (this is known as repetitive reproduction). This then gives rise to bacteria.
Thus, this explains the answer.
I believe the answer is...
Bioconversion
Three ways scientists base their identifications of evolutionary relationships are:
1. Does not take genetics into account.
2. Does not consider convergent evolution.
3. Physical similarities does not mean that they are related.
Evlutionary relationships talks about relatedness between organisms, usually this can be shown by a phylogenetic tree through phylogeny. Reconnection and speciation of organisms must be considered in studying relatedness of organisms.
