When viewing the shape of a human cheek cell, what microscope would most likely be used?
A.) Light
B.) Dissecting
C.) Transmission Electron
D.) Scanning Electron
Answer:
Your answer Is C!!!!! :)))
Explanation:
A light microscope can be used to view the shape of a human cheek cell. So the correct option is A.
What is a light microscope?In many research labs, including those using electron microscopes, light microscopes are crucial tools. They can be used to support electron microscopy or as the main viewing tool. The methods used to prepare samples for light microscopy are constantly expanding, and they might include everything from tissue cultures and sliced biological creatures to samples from the sciences of materials and geology.
There are significant parallels between the optical principles of light and electron microscopes. Understanding the operation of a light microscope is essential for both getting the best possible light pictures and comprehending electron microscopy.
We make use of the waveform characteristics of light in microscopy. When generated at a specific source, these waves vibrate perpendicular to the direction of transmission. There are peaks and troughs on every wave. One wavelength is the length of the light ray's onward journey (lambda). The color and intensity of the source affect the wavelength.
Therefore the correct option is A.

In an experiment, Dr.Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. The amount of calcium ____ variable. The risk of bone fractures _________.
1. A reliable
An independent
A dependent
2. Can be changed by the participants
Can be changed by the researcher
Could change with calcium intake
Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.

Using this information and what you learned about mechanisms of gene expression, why do cats have such fur pigmentation
Answer:
Explanation:
Gene expression is when information from a gene is used to product a gene product, this product enables to produce protein as the end product.
Phenotype which is the physical expression of the genetic make up gives the gene expression.
Cat having a fur pigmentation indicates the presence of a functional protein that has fur i.e the genetic make up of the cat has fur which give rise to the phenotypic expression.

O a. The substance is from an animal source.
O b. The substance is the poison ricin.
O c. The substance is from a plant source.
O d. The substance is a lipid.
Answer:
a. The substance is from an animal source.
Explanation:
Glycogen is a carbohydrate polymer in which animals store their excess glucose as. When animals digest their ingested food, it gets broken down into GLUCOSE. This glucose, when in excess, gets stored as GLYCOGEN.
According to this question, a substance found at a crime scene is being examined using chemical tests. The test revealed that glycogen is present in the substance. This can mean that the substance is from an ANIMAL source because GLYCOGEN is only present in animals.
Answer:
a. The substance is from an animal source.
Explanation:
I, myself, took the exam, but also glycogen is found in animals cells. It is a branch of glucose that is usually stored in liver and the skeletal muscle.
