Heat, light, sound and fire may have been involved when the Bunsen burner was lit with the spark from the Van de Graaff generator. Bunsen burner is a common device in the lab.
<h3>What is a Bunsen burner?</h3>
Bunsen burner is a laboratory device (gas burner) that generates a single open gas flame.
The gas most commonly used in Bunsen burner is generally natural gas, i.e., methane gas.
This device (Bunsen burner) can be used to generate a heat source during a lab experiment.

Answer: From top to bottom- T, C, G, A, T, A, T
Explanation:
These are the nitrogenous bases that make up a part of nucleotides in DNA. 
There are 4 bases in DNA: 
- Adenine 
- Guanine 
- Thymine 
- Cytosine
The bases pair together from A to T and G to C, the way I remember is just reading it as AT GC and it works for me, but you make want to make an acronym if it helps you remember better. 
As a result, all you have to do is type in the corresponding base to form the correct base pairs.

Answer:
The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>
Explanation:
The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
