Answer:
Rhizomes are modified stems running underground horizontally. They strike new roots out of their nodes, down into the soil. They also shoot new stems up to the surface out of their nodes.
- Kaibab Squirrel gives us one nice example of the evolution that is caused by geographical isolation - about 10,000 years ago when the last Ice Age ended, physical formations in the valley changed in a way that prevented squirrels from reaching the Colorado River. The valley has become a geographical barrier separating forests and squirrels on each edge. One group of squirrels became two separate groups that were no longer able to mate, kaibab squirrels. Abert squirrels are North American species, found across a group of locations. Kaibab squirrels are a subspecies of Abert squirrels, found only in one region in the United States. - Kaibab and Abert squirrel live in ponderosa pine forests, where they build nests of twigs and pine needles. They eat nuts, fruits, and fungi, as well as seeds, bark and twigs from the trees they make at home. The most important source of food in the squirrel Kaibab is the seeds contained in the cones of ponderosa
Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

What is DNA molecule?</h3>
- Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
- Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
- An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
- To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.

It is important for a scientific claim to be accurate because a scientific claim is supposed to be able to be trusted and it needs to be credible. To develop a scientific claim you need to first test your theory many times to make sure that the same result happens every time.
Hope this helps
Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be <u>to make an exact copy of a DNA strand for bacterial reproduction.</u>
<em>DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction. </em>
Without reproduction, DNA replication would not have been necessary.
