Van der Waals interactions may result when electrons are not symmetrically distributed in a molecule. Van der Waals forces, in physical chemistry are essentially
associated with the name of a Dutch researcher Johannes Diderik van der Waals
and indicate the separation of dependent interactions among particles and
atoms.
The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.
We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.
Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.
The answer is:
The F1 generation will have all cleft chin.
The P generation and F2<span> generation will have cleft chins and no-cleft chin.</span>
Magnetic reversals C. PROVIDE STRONG EVIDENCE FOR SEAFLOOR SPREADING.
Magnetic reversal is evident when the <span>change in the Earth's magnetic </span><span>field results in the magnetic </span><span>north being aligned with the geographic south, and the magnetic </span><span>south being aligned with the geographic north. It is also called geomagnetic reversal</span><span>.</span>
Magnetic reversals can occur in less than 100 years. It led to extinction events during the pre-historic times. Because the magnetic field is rapidly weakening, magnetic reversal may cause biblical floods.
