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:
São Paulo is a city in Brazil that faced the worst drought in Brazil in the last 100 years between 2014–17.
The reason of the drought was diminished rain falls from last three third consecutive year in the region. Humans were somewhere responsible for the drought and less rainfall because this was caused by expansion of deforestation into the Amazon basin. Deforestation disturbed the environmental cycle that caused less amount of rain in São Paulo, Brazil.
Answer:
The correct answer is option C. they amplify the original signal manyfold.
Explanation:
A phosphorylation cascade is a chain or sequence of the reactions that are categorized by the events where one enzyme phosphorylation another up-to phosphorylation of thousands of proteins.
The phosphorylation cascade can be experienced in involving the protein kinases as they the signal transduction of different cellular hormone messages due to their ability to amplify the original signal multiple time and make it more effective.
Thus, the correct answer is option C.
Answer:
Answer: Desert mole excretes concentrated urine with urea. Marine fish excretes urine with uric acid. Tilapia excretes dilute urine with amino acids.
Cells get energy for their functioning through sunlight and other organic food molecules. ATP is a good example of energy pathways through photosynthesis.
