What name is given to a discrete packet of light?
a) phaser
b) wavelength
c) photon
d) quantum

The correct answer is: C) photon

Light has the unique characteristics of both a wave and a particle at the same time.

Characteristics of wave: reflection, refraction, diffraction.

The particles that make up light are basic units of light called photons ( a bundle of electromagnetic energy) or quantum of electromagnetic energy. Photons have no mass, no electric charge, have  energy and momentum which are dependent on the frequency…

b. the carbon cycle ensures living things have a source of hydrogen

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
