If a person was interested how light passes through clear substances, what field of science would be the best course of study?
1. thermodynamics
2. electromagnetism
3. quantum mechanics
4. optics
Answer:
4. optics
Explanation:
If a person was interested in studying how light passes through clear substances, the field of science which would be the best course of study is optics. Optics refers to the field of science which typically deals with the study of light and infrared radiation, as well as their interaction with substances or objects (matter).
This field of science (optics) makes it possible for scientists and researchers to observe the propagation of light from a source through a medium, understand the behavioral patterns and properties of light.
In a carbon cycle, organisms exchange carbon dioxide with the atmosphere. What will likely happen if plants are removed from the carbon cycle?
The process of respiration will occur, but less amounts of carbon dioxide from the atmosphere will enter the living system.
The process of photosynthesis will not occur and as a result, carbon dioxide from the atmosphere will not enter the living system.
The process of respiration will occur, but organic carbon will not be converted to carbon dioxide for release into the atmosphere.
The process of photosynthesis will not occur and as a result, carbon dioxide will not be released into the atmosphere.
D carbon dioxide will not be released
Which type of ecological succession would experience the greatest species diversity at the beginning of succession? Why?
Answer:
Secondary succession
Explanation:
There are two types of ecological succession that include primary succession and secondary succession.
Primary succession occurs in new lands that provide a habitat to be colonized for the first time while a secondary succession occurs when a place that is pre-occupied by pants or living things is disturbed and then re-colonized.
Secondary succession would experience the greatest species diversity at the beginning of succession because all the minerals and nutrients required for the growth will be already present in the place. Whereas in primary succession, it takes ages to form soil and then colonize it.
Hence, the correct answer is "Secondary succession".

why is it important for our bodies to get rid of built up hydrogen peroxide in our bodies
Answer:
To protect itself, the body makes catalase, the enzyme that decomposes hydrogen peroxide before it can form hydroxyl radicals. Actually, the formation of hydrogen peroxide in cells is an attempt by the body to protect itself from an even more dangerous substance, superoxide.

Which pair of scientists should Elizabeth write instead of X and Y?
Schwann and Hooke
Hooke and Schleiden
Hooke and Leeuwenhoek
Virchow and Schwann
Answer:
Schleiden had even supposed the nucleus to be a constituent part of the wall, sometimes lying enclosed between two layers of its substance, and Schwann quoted this view with seeming approval. Schwann believed, however, that in the mature cell the nucleus ceased to be functional and disappeared.
Answer:
The answer is Hooke And Leewenhoek
Explanation:
Hooke was the first person to call use the name "cells". Leewenhoek called his cell the "animalcell" and he used his own microscopes.

A patient is found to have Maltase enzymes but cannot breakdown maltose. Write an explanation as to why the patient cannot breakdown maltose using your knowledge of enzymes.
Answer: It seems that maltose is unable to bond the maltase. Perhaps an inhibitor bound itself to the active site, so maltose cannot. Perhaps an inhibitor bound itself to the allosteric site changing the shape of the active site.

Fiona did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. She placed a ray box in front of a mirror. She changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light.
Which of the following is the independent variable in this experiment?
The mirror used to reflect the light
The ray box used as the source of light
Angle at which the light from the ray box strikes the mirror
Angle at which the mirror reflects the light from the ray box
Answer:
