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.

In the human body, which of the following is considered an external defense in the prevention of disease? Mucous O Histamines O Antibodies O Fever
Answer:
I believe it would be Mucous
Explanation:
Since Histamines and Antibodies are chemicals that are inside a human body they are not an external defense. Also, a fever can only happen if the disease gets inside the body, thus its not an external defense. All this leaves only one option out and that is Mucous.

Binary fission occurs in which of the following type of organsim?
Answer:
A. Prokaryotes like bacteria
Explanation:
Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).
Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.
The answer is thus A.

what controls traits and inheritance?
Answer:
Genes
Explanation:
Gregor Mendel discovered in his experiments that a factor determined the physical characteristics of an organism. This factor is called a gene. A gene is the molecular unit of heredity in a living organism.
Genes are segments of DNA that holds the information needed to build and maintain an organism and pass genetic traits to offspring. The trait of an organism, which refers to the physical characteristics of an organism, are passed from parents to offsprings via genes. The genes also contain variant forms called ALLELE that determines which trait an organism will possess.
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.
