Answer:
C. They all use a cut and paste mechanism.
Explanation:
DNA transposons can go through a replicative or nonreplicative transposition.
The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.
The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.
Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.

Answer:
c. smear preparation
a. fixation
b. application of staining dyes
Explanation:
In the bacterial specimen preparation and staining order, the first step would be Smear preparation in which the smear of bacteria is formed on the slide.
Then the bacterial smear is heat-fixed so that the smear does not get washed off during the washing process in the staining procedure. After heat fixing the bacterial smear, the dyes are applied to the bacterial smear to stain the bacterial cells.
Therefore the correct order is-
c. smear preparation
a. fixation
b. application of staining dyes
Answer:
Homologous features
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
<span>Rather than being learned, glucose aversion is inherited as an autosomal incompletely dominant trait, which appears to he controlled by
a single major gene. This was discovered through a study done on cockroaches, some were fed regular bait while some were fed bait laced with glucose. Through time they began to avoid the glucose.</span>
