C) refract
Explanation:
When light passes from air into water, the light waves will bend or they refract and the pencil will appear to be broken.
In normal space, light travels along a straight path with no alteration of the path along which it travels.
- When light crosses the boundary from a denser to a less dense medium, it is refracted.
- Refraction implies that the angle of the light is bent.
- This is because the new medium causes the light rays to slow down compared to the speed it was coming forth with.

RDA stands for Recommended Daily Allowance. To determine the amount needed of a certain adult per day, we simply multiply the mass of the adult to the value of RDA. For this case, we do as follows:
Daily requirement = 12 mg/kg ( 78 kg ) = 936 mg of lysine = 936000 g
Well, basically because the observations can help you out during the experiment.

Excessive ventilation is harmful because it increases intrathoracic pressure, decreasing venous flow and causing problems in the conduction of heartbeats, since it changes the respiratory pattern. In addition, it can cause occasional problems such as reflux and regurgitation.
