Which of the following is the preferred degree for a seismologist?
a. biology
b. engineering
c. geoscience
d. physics

The preferred degree for a seismologist is a geoscience degree.

Refer to the following passage in the Edg assignment:

"Most entry-level positions for those working in the field of geoscience are required to have at least a bachelor’s degree; however, college teaching and high-level research positions require a PhD. Although a geoscience degree is preferred, degrees in computer science, engineering, mathematics, biology, chemistry, and physics are accepted by most employers as long as some coursework in geology was included. Also, applicants with laboratory and field experience are highly desired by employers."

can you attach a picture of the lettuce? : )

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
