Mitochondrial DNA mutation occurs at a constant rate throughout history. Thus, each different base in Mitochondrial DNA is able to show just how long ago the 2 species diverged from each other.
Hope this helps! :)
This is what is commonly know as 'peat'. Peat is found in peatlands, bogs, mires and moors, and is an accumulation of partially decayed vegetation or organic matter. The decay is slowed down by a lack of oxygen due to waterlogged conditions. These areas are very important carbon sinks as the CO2 released by the decaying matter is trapped within the peat. It requires thousands of years for peatland to develop. Peatlands are very important as they provide a record of past vegetation and climate within the preserved plant remains.

Explanation:
The definition of transformation in bacteria is described by the first statement: transformation is the assimilation of external dna into the bacterial cell. In a more elaborate sense, transformation is described by the altering of the cell as a result of the uptake or intentional incorporation of dna from an external source. It is one of the three processes for horizontal gene transfer. The other two are transduction (infection of a phage), and conjugation (transfer of dna between two bacterial cells that are directly in contact).
Answer:
Considering what research tells us about encoding and retrieval, the teacher would be well advised to help students encode information about the cell <em>in both visual and verbal forms.</em>
Explanation:
Psychological studies have shown that images are able to generate better memories in a person. Anything which is learned through images will be remembered by the human brain for a longer period of time.Also, anything which is learned from a language which the brain interprets is known to generate memories. Hence, both visual and verbal forms of learning would help the students to learn components of a cell.
