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:
Option B, chemical energy to thermal energy
Explanation:
All living organism feed on food that contains energy in the form of chemical energy. Once the food is intake and processed for fulfilling energy requirement of all metabolic processes with in a cell, the remaining energy is released as heat (thermal energy). Thus, an amoeba while consuming a sugar molecule converts chemical energy with in the sugar to thermal energy in the form of energy molecules.
Hence, option B is correct
Answer:
Explanation:
Based on what is known about the fetal skeleton and the ossification process it can be said that this occurs due to babies having more of the osteoblasts bone cells. These cell's main function is to lay down new bone material, this therefore creates a thicker harder bone which allows for proper support so that the body can continue growing and become stronger overall.
Answer: Burning Fossil Fuels
Explanation: Technically getting rid of anything on this list would reduce greenhouse gas emissions burning fossil fuel releases 50 billion tonnes of CO2e each year texting on cellphones is estimated to emit 32,000 tons CO2e per year and eating meat is estimated to emit 3.3 tons of greenhouse gas emissions.
