Answer:
Bacteroides plebeius which is present in the gut humans have the same genes to marine bacterium Zobellia galactanivorans.
Explanation:
many researchers findout that bacteroides plebeius acquired functional porphyranase and agarase genes from a marine bacterium called Zobellia galactanivorans. Zobellia galactanivorans is a marine bacterium which has the ability to digest complex polysaccharides such as agarose and porphyran. so due to similar genes, Bacteroides plebeius also digest polysaccharides such as agarose and porphyran present in sea weed.
Evolution can be defined as the process of the change occurring in a population over a period of time through genetic variation. This genetic variation and the process of natural selection help a species to evolve by selecting the traits that helps it to better adapt to the environment. These genetic variations are inherited over time as the species continue to evolve.
Hence, the correct answer is 'change in population through genetic variation over time'.
The answer is cytoplasm
cytoplasm is a gel in the cell and contains the cells organelles :)))
i hope this is helpful
have a nice day
<u>Answer:- </u> <em>Option a </em>radial symmetry
<u>Explanation:- </u>
Most of the organisms have can either of the two types of symmetry:-
1. <em>Bilateral symmetry</em>- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a <em>single</em> plane.
For e.g if you cut the letter M from middle vertically then you have two equal halves.
2. <em>Radial symmetry</em> - A body is said to be radially symmetrical if it can be divided into similar halves in <em>any</em> plane. This means that the organism has its body parts arranged around a central main axis.
The <em>cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.</em>
A because it is used to treat known diseases.
