Answer:
B. ...includes methods like metagenomics, which sequence and interpret all the DNA in an environmental sample.
Explanation:
Environmental microbiology is the science in charge of the study of microorganisms, small living things known as microbes. Study organisms that are only visible through a microscope, such as prokaryotic and simple eukaryotic organisms.
Metagenomics is the study of a collection of genetic material from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. It is generally used when studying microbial communities in which one microorganism cannot be separated from another.

<h3><u>Answer and Explanation;</u></h3>
- <u>Endosymbiotic theory</u> explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
- On the other hand according to the <u>autogenous hypothesis, </u>mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.
- <u>Endosymbiont theory </u>is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
- <u>Autogenous theory</u> is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
- <u>Horizontal gene transfer theory</u> is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.
Answer:
The size of a population of microorganisms in liquid culture may bemeasured by counting cells directly or by first diluting the original sample and then counting cell numbers (see below), or by taking some indirect method such as the turbidity (cloudiness) of the culture.
