Answer:
Withdrawal methods, breast feeding methods
Answer:
Both aristotle and ptolemy models stated that the planets rotate on their axis. Both models stated that the planets and objects in the solar system have small orbits called epicycles. The both persons are stated that the sun is the center of the system around which objects have elliptical orbits.
Answer:
Carbon can form four covalent bonds
Explanation:
Answer:When we increase the temperature of one of the reactants in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases the chance of a more successful collision and the rate of reaction.
Explanation:
Answer:
mutation rates can be used to design molecular clocks in order to estimate divergence times among species
Explanation:
In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).
