Answer: A double-stranded DNA molecule is unwound into single strands. Polymerase matches the right nucleotides to the single strand so that each forms a double strand of DNA.
Explanation: During replication, a double-stranded DNA molecule is unwound by an enzyme known as helicase into two single strands of DNA that serve as templates for new strands of DNA.
Then another enzyme known as DNA polymerase matches the free and right nucleotides to the nucleotides on the single DNA strands (templates) to form a double-stranded DNA molecule.

Answer:
They must shed their exoskeleton, or molt, in order to grow. The exoskeleton splits open. the animal emerges and swells to a larger size until the newer, larger exoskeleton is hardened.
Answer:
The correct answer would be - Dd Pp.
Explanation:
As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP
. similarly the recessive trait that is dwarf and pubescent plant would be ddpp
Thus, the cross between these would be -
DD PP x ddpp
And gametes would be - DP,DP, dp, and dp.
So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype
.
Thus, the correct answer would be - Dd Pp.
The nurse should ask one more time and if the answer is no then they should accept the answer because they are not able to help the problem if they don't have more information.
