Key physical features. All three species share similar physical characteristics - a relatively small body and a 'robust' or strongly built skull including large lower jaws with extremely large molar teeth.
ATP or Adenosine Triphosphate is the energy that cells produce in order for an organism to perform well. In plant cells, ATP and glucose are produced during the process of photosynthesis. This process occurs along the cristae or walls of the mitochondria and the chloroplasts.
Chloroplasts are the unique membrane of plant cells where ATP is produced and energy is converted into food that the plants use to sustain themselves. Mitochondria are membranes that are found within most eukaryotic cells (cells with nucleus); they also generate ATP for the plants energy and breakdown glucose (sugar) for the plants food.
Restriction enzymes can also be used to generate compatible ends on PCR products. In all cases, one or more restriction enzymes are used to digest the DNA resulting in either non-directional or directional insertion into the compatible plasmid. The most common Type II enzymes are those like HhaI (NEB #R0139), HindIII (NEB #R0104), and NotI (NEB #R0189)
Answer:
The size of the moon ensures that it has some considerable gravitational force associated with its mass. This is unlike asteroids that are not large enough to have significant gravitational forces associated with their relatively low mass. Therefore when the moon was molten in its early years of formation, gravity due to its mass, caused materials to be pulled down towards its center. The molten rock, before it cooled into solid rock, got distributed more or less into a sphere because the force of gravity pulls from all sides from the center of mass.
