Answer:
Genetic engineering has its grass roots from the recombinant technology.
Explanation:
Genetic engineering is seen to have started from a scientists activity which involved restriction enzymes and DNA ligases that were used by Paul Berg in 1972 to create the first recombinant DNA molecules. A monkey virus which is SV40 was combined with a lambda one. Following that, the results of the experiment and attempts were further investigated by other scientists and later, the first plant that underwent genetic engineering was the plant tobacco.
They are haploid because they result from meiosis

Grass because without it none of those species would be living
The student put under the "physical changes" portion of the poster about aluminum is option "B".
<h3>What is the boiling point and melting point of aluminum?</h3>
The melting point of aluminum is 933.47 Kelvin, 660.32 degrees Celsius, or 1220.58 degrees Fahrenheit.
It's normal boiling point is 2792 Kelvin, 2579 degrees Celsius, or 4566 degrees Fahrenheit.
Thus, Options "B" aluminum met at 660 degree celcius.
