Answer:
The correct answer will be option- A and D
Explanation:
<em>E.coli</em> is a bacteria which is pathogenic to humans and<em> E. histolytica</em> is an amoeba which is a parasite. Both are different species but both are single-celled organism which to survive share feature among them.
The common characters shared by these two species are: they depend on the source of energy for their survival which they usually get from the hosts.
Both the species reproduce to produce progenies like them which help them maintain continuity of the species of Earth.
Thus, options- A and D are the correct answer.
The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
The answer is The ions are protected inside the lipid bilayer so that it is not pushed back to a more polar environment.
The lipid bilayer is mainly composed of lipids (phospholipids and cholesterol), and is also composed of proteins such as transporters.
The ions (which are polar) can not cross directly through the lipids because they will repel them due to their apolarity. On the other hand they can easily pass through protein channels that will protect them during their passage (the proteins are more polar than lipids).
Chao should use a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of thin plastic sheets floating on top of the liquid. This part of the experiment will best depict plate tectonics because of the variables that can be seen
hope this helps
