How does this image compare to the white blood cells you saw using Stella’s compound microscope? What are the pros and cons of using electron and compound microscopes? In your response consider cost and ease of use.
Answer:
The Resolution and Magnify power are the major differences between the electron microscope compare to compound microscope. This is due to the source of power for the operation,Light rays of (400-700nm) are used by the compound microscopes,while short frequencies beam of electrons of( 1 nm)are used by the Electron Microscope.
The compound microscope consists of objective lens with short focal length.They are therefore used for magnification of tiny objects.While the E. microscope makes use of beam of electrons(compare to light rays in the compound microscope) with higher resolutions.The beam of electrons are focused by magnetic lenses to give images.
Electron microscope is cumbersome to use,it is expensive, requires a lot of expertise, and occupies large space.
Compound are less expensive with low maintenance,it does not requires expertise;very easy to operate, and can easily be moved about.
There is low risk of radiation with compound,lower magnification,both dead and living creatures can be used.
E.microscope,has high radiation risk,higher magnification, with only dead materials.
Explanation:
White blood cells are the immune cells that protect the body. They are also known as leukocytes or leucocytes.
The compound microscope magnifies objects lesser than the electron microscope. We can see higher magnified things in the electron microscope.
Pros and cons of electron and compound microscopeCompound microscopes are easier to move and set up because they are small and light.Electron microscopes are heavy and higher. They are harder to set up and move.Electron microscopes use electromagnet glasses, whereas compound microscopes use glass lenses.Compound microscopes are cheaper than electron microscopes.Thus, these are the pros and cons of Compound microscopes and Electron microscopes.

Leukopenia is a condition characterized by a decrease in white blood cells. What effect does leukopenia have on the body's ability to fight infection?
Answer:
This increases their risk of infections
Explanation:
Leukopenia is a condition where a person has a reduced number of white blood cells. This increases their risk of infections. A person’s blood is made up of many different types of blood cells. White blood cells, also known as leukocytes, help to fight off infection.
Leukopenia is a condition, which leads to a low amount of white blood cells, in which major cell neutrophil fight for infection, making a person more susceptible to infection.
What is leukopenia?In the leukopenia condition amount of white blood cells is fewer than 4000 cells per microliter of the blood, having higher chances for infection.
In the immune system, some cells have to fight infection in the body to eliminate any kind of infection, the neutrophil is the kind of leucocyte that help to prevent infection.
There are some consequences of leukopenia, like delay in the cancer treatment, and sepsis which is a life-threatening response to blood infection.
Therefore, leukopenia is the condition for a decrease in white blood cells, and this cells play major part in the immune system to fight the infection.

What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.
Answer:
The body would break down existing muscle to get the amino acids it needs.
Explanation:
If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
What is the function of proteins?Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.
Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.

Describe the process of mitosis and meiosis.
Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
The process of dividing the pre-existing cell into two or more daughter cells is called cell division.
Mitosis
Mitosis is defined as the division of the cell in which a single cell divides to form two daughter cells, having the equal number of chromosomes as present in the mother cell. In mitosis cell division, chromosomes duplicate and equally distribute into two diploid cells. Thus as a result, all the daughter cells come to have the same number of chromosomes compared to the mother cell. It occurs in somatic or vegetative cells.
Meiosis
Meiosis is a types of cell division in which a mother cell divides into four daughter cells and each daughter cell having only the half number of chromosomes as compared to mother cell. Meiosis cell division comprises two divisions: Meiosis I and Meiosis II
The meiosis I division is also known as reduction division. This is because it involves the formation of two daughter nuclei with just half number of chromosomes as that present in the another cell. more over, in the prophase stage of meiosis, crossing over ( interchange of chromosome segments between two homologous chromosomes) takes place. This causes the variation in the off-spring and gas a role in evolution.
The meiosis II is also called equational division because the number of chromosomes remains the same in the daughter nuclei as after meiosis I. In this way, four daughter haploid nuclei formed. Then the divison of cytoplasm of the cell ( cytokinesis) takes place and all nuclei get their own cytoplasm and form four haploids.

The paramecium was the only unicellular organism that Stella viewed through her microscope. All the other organisms were multicellular. How was the unicellular specimen different from the multicellular organisms?
Answer:
The difference between a unicellular specimen and other multicellular organisms will be the NUMBER OF CELLS. See detailed explanation below.
Explanation:
Cells are the simplest and basic unit of life. Living organisms has been classified as unicellular or multicellular depending on the number of the cells that make them up. A unicellular organism is that which possess only one cell to carry out all its life functions. According to the question, the Paramecium is an example of unicellular organism.
On the other hand, a multicellular organism is made up of many cells that specializes to perform the different life functions of the organism. This means that a specific kind of cell carries out a specific life function, this is called Cell differentiation. Examples of multicellular organisms include plants, all eukaryotic fungi etc.
Therefore, Stella's unicellular specimen, which is the Paramecium, will be different from other multicellular organisms in the number of cells possessed by each of them. The unicellular specimen will possess just a single cell while the multicellular organisms will possess more than one cell as viewed by the microscope.

How does the structure of epithelial tissue help it to perform its function? Its ability to conduct electrical signals allows for control and coordination of body movements. Its fibrous layers allow the tissue to be a strong yet flexible binding agent. Its contractile cells that make up the tissue allow for movement. Its tightly packed cells allow for protection against harmful substances.
Answer:
Explanation:
Epithelial tissue consists of tightly packed sheets of cells that cover surfaces—including the outside of the body—and line body cavities. For instance, the outer layer of your skin is an epithelial tissue, and so is the lining of your small intestine.
Epithelial cells are polarized, meaning that they have a top and a bottom side. The apical, top, side of an epithelial cell faces the inside of a cavity or the outside of a structure and is usually exposed to fluid or air. The basal, bottom, side faces the underlying cells. For instance, the apical sides of intestinal cells have finger-like structures that increase surface area for absorbing nutrients
