Answer:
The number of possible trees increases only linearly with the number of components one is comparing
One can use DNA, RNA and/or protein sequences.
It is possible to estimate which species are separated by less evolutionary distance.
Explanation:
The pylogenetic analysis is a process to estimate the evolutionary relationship. The sequence of a gene, DNA, RNA or protein can be used to assess the evolutionary relationship of species. Phylogenetic tree increases only linearly with the number of components. It is possible to estimate which species are separated in divergence time by less evolutionary relationship.
<em>Radioactive tracers are useful in </em><em><u>determining medical problems.</u></em>
Answer: <em>B. Determining medical problems.</em>
Explanation:
Radioactive tracers are comprised of carrier particles that are reinforced firmly to a radioactive atom. These bearer particles shift incredibly relying upon the motivation behind the scan.
A few tracers utilize atoms that associate with a particular protein or sugar in the body and can even utilize the patient's very own cells.
Examples of radioactive tracer are - tritium, carbon-11, carbon-14 and oxygen-15 and so forth. Radioactive tracers are either injected in the body intravenously or orally.
The correct option is this: IT HAS PEPTIDOGLYCAN.
Eubacteria are those bacteria that are considered to be real bacteria and they can be found virtually everywhere. They are prokaryotes and thus lack true nucleus. They are normally categorized based on their shapes. One specific characteristic of eubacteria is their possession of cell walls that are made of peptidoglycan, this chemical strengthen their cell wall and enhance their ability to withstand hostile environments.
