True
Explanation:
Atoms of different elements have different masses because different atoms have a different number of subatomic particles i.e neutrons, protons and electrons.
Answer:
Mutation
Explanation:
Mutation creates new genetic variation in a gene pool. It is how all new alleles first arise.
Answer:
Water molecules are broken down into H+ ions, electrons, and oxygen molecules. The water molecules provide the H+ ions and electrons that are used in the light-dependent reactions.
Explanation:
Other crystals can be similar or same shape.
Explanation:
Type II restriction enzymes are the familiar ones used for everyday molecular biology applications such as gene cloning and DNA fragmentation and analysis. These enzymes cleave DNA at fixed positions with respect to their recognition sequence, creating reproducible fragments and distinct gel electrophoresis patterns. Over 3,500 Type II enzymes have been discovered and characterized, recognizing some 350 different DNA sequences. Thousands more ‘putative’ Type II enzymes have been identified by analysis of sequenced bacterial and archaeal genomes, but remain uncharacterized.
