Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the naked eye.
Answer:
Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus.Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
If you are conducting a study on the health of people who have been exposed vs not exposed, the method you should use to obtain data would be an observational study because it involves the pre-existing condition of the subjects.
Each hydrogen bond will form ONE COVALENT bond with the other atoms in the molecule. Hydrogen has only one atom; to form a covalent bond, it has to donate one electron and the other atom that hydrogen is bonding with will donate one electron also, making two. These two electrons will be shared between the two, making the atoms to have two electrons each.
