What are the three main states of matter? They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. Can be compressed into smaller spaces? Because there is space between the particles, they can be squashed into a smaller volume when the gas is compressed….particles are fixed to […]

How do you write a DNA sequence from mRNA? DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3′ T C G T T C […]

Is CRT TV bad for eyes? There are two things about CRTs that can potentially damage eyesight. #1 is staring at the same close-range object for hours at a time, causing eyestrain. The muscles that focus the lens are forced to hold one position for a long time, and that can hurt them after too […]

How energy is transformed in our body? All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and […]
