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.
Answer:
The correct answer would be 37.
Egg or sperm or gametes are cells produced by the process of meiosis and carry half the number of chromosome (n) present in a parental cell (2n).
Meiosis is a type of cell division which results in the formation of four daughter cells each having exactly half the number of chromosome present in parent cell.
The sperm unite or fertilize with egg which restore the chromosome number (2n) in the zygote.
Answer:
In genetics, Hh means a heterozygote.
Explanation:
Usually, in genetics, H would be the dominant, and h would be the recessive trait. HH is usually dominant, and hh would be recessive. So, Hh would mean a heterozygote. In a heterozygote, this would mean that the recessive trait is in the genotype, but the dominant trait would still take over. This also means that sometimes, the recessive trait can be shown along with the dominant. This can be possible through co-dominance, and incomplete dominance. Hope this helps!
