Answer:
C. The bacteria that survived were transformed with plasmid that contains the resistance gene for ampicillin.
Explanation:
Plasmids are small, circular double stranded DNA molecules that are found in bacteria. It carries genes that provides the bacteria with an advantage.
There are five types of plasmids namely, Fertility F-plasmids, resistance plasmids, Virulence plasmids, degenerative plasmids and the Col plasmids.
Ampicillin is an antibiotic that is supposed to kill the bacteria. However, most bacteria have resistance plasmids that can lead to antibiotic resistance.
That explains why some of the bacteria survived.
The effect of temperature or nutrition on the expression of genes are examples of how <u>the environment </u>can alter the phenotype.
Increases in temperature (warm environments) showed a non-significant increase in a phenotypic manner and a marginally significant increase in phenotypic variability. Larger increases in temperature noticed extra increases in phenotypic variability, but no increase inside the mean phenotypic response.
Usually, growing temperature induced an acceleration inside the improvement, and the higher the temperature, the sooner the expression reaction of any particularly focused gene. In more detail, larval yolk utilization and growth rates multiplied, while yolk utilization performance decreased with increasing temperature.

Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
