Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.
<h3>What is a phylogenetic tree?</h3>
Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.
A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.
Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.
Thus, every individual of same species are related to each other, so scientists can analyze another specimen from the same species.

Answer:
picture? I'll try to answer. It's not B. It's either A, C, or D, but it is <em>most likely</em> not C, So I would honestly say it is probably D
About 20 minutes<span>Sperm can live outside of the body for only about 20 minutes
to an hour, depending on how exposed the semen is to the air and other
environmental factors. To avoid the slightest risk of pregnancy, a woman
should make sure that ejaculated semen doesn't get at all close to her
vagina.</span>
Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).
Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.
Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.
