1 Molecule of MgCl2 = 95.11
1 Mole in 1 molecule of MgCl2 is
1
95.11
= 0.010514
Or Total moles in 309 gm of MgCl2 is #0.010514*309 = 3.2488
Answer is 3.2488 moles
Areas in the DNA that contain repeated segments are the basis for DNA fingerprinting.
DNA fingerprinting is used to check whether there is a family relation between two persons. It is also used to identify the organisms that may be reasons for diseases. Furthermore, DNA fingerprinting are used in solving crimes.
Answer:
If one plant is named Salvia greggii and another is named Salvia vanhouttei, what this tells me about these plants is that they belong to the same genus and to different species. If you remember from your biology classes, genus always has the first capital letter, and species is all in lower case.

Explanation:
. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.
5.Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Because we have smelled them so long we are used to them
