Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
The three organisms that belong in the same phylum as your Protist are:1. Algae: Algae are plant-like Protist and are all photosynthetic Protists. 2. Protozoa: Protozoa are animal-like Protists3. Heterotrophs: Heterotrophs are fungi-like Protists. An example is what is known as True Slime Moulds.
A Protist is any organism that is not a plant, animal or fungus. They are normally unicellular, although some can be multicellular, for example, Algae. They all have a nucleus and they mostly live in water.
The analysis of total microbial genomes in an environment is called metagenomics and the total microbial genomes in an environment (or the total microbial community itself) is called a microbiome.
<h3><u>
Explanation:</u></h3>
The study that is associated with the genetic materials that are obtained directly form the sample in an environment refers to the term Meta genomics or ecogenomics or community genomics. It can be considered as the process through which the meta genome is produced.
The genetic material of the microbes such as fungi, bacteria, viruses and protozoa refers to microbiome. These microbes lives inside the body of humans. The weight may range upto 5 pounds for these microbiomes. Micorbiomes are the total number of micro genomes that are present in the environment.
I think option a is the correct answer
