Saturn is the least dense planet in our Solar System. It is made up of mostly hydrogen and helium, which are the two lightest elements in the universe and thus make Saturn the lightest planet that we know of. This could Possibly be the answer!!
<span>Prokaryotes lack a distinct cell nucleus and their DNA is not organized into chromosomes. They also lack the internal structures bound by membranes called organelles, such as mitochondria.</span>
Answer:
DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.
Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.
The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.
The points where DNA is currently unwinding are called replication forks.

Answer:
D?
Explanation:
Im assuming the last one is "The number of cells in its body". If so, that is the right one.
Answer: Option D) Peptide bonds are amide linkages.
Explanation:
A peptide bond is formed between two amino acids with the loss of one molecule of water and the formation of an amide (CO-NH2) bond.
Usually the carboxyl group (COOH) of the first amino acid links with the amino group (NH2) with the loss of H2O, thus forming an amide linkage
