The planets that reside in the <u>Outer </u> region of the solar system are Jupiter, <u>Saturn</u>, Uranus, and Neptune. Although these planets are made up of lighter elements, they have a solid core. The atmosphere of all these planets is made up of hydrogen and <u>helium</u>. In addition to these two elements, the planets Neptune and <u>Saturn</u> contain methane.
Answer: Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
The great majority of the cell divisions that happen in your body involve mitosis. During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
In all of these cases, the “goal” of mitosis is to make sure that each daughter cell gets a perfect, full set of chromosomes. Cells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a carefully organized series of steps.

Answer:
Deoxyribose
Explanation:
DNA stands for "deoxyribonucleic acid" because it has the sugar deoxyribose. It's named because it has one fewer oxygen than ribose. Be careful not to confuse the two sugars--ribose is in RNA, which stands for "ribonucleic acid."
Attached is a picture of the differences between the two sugars.
