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:
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.
Answer:
14. 2.5% of water is freshwater
Answer:
B) 70S ribosomes and circular DNA
Explanation:
Remember: Mitochondria is found in the cytoplasm of almost all <u>eukaryotic</u> cells.
All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.
Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.
