Answer:
In acid-fast staining, carbon fuchsin is used as a primary stain which dissolves the mycolic acid present in the cell wall of <em>Mycobacterium smegmatis </em>and penetrates through it which results in staining <em>Mycobacterium</em> red.
Staphylococcus aureus cell wall does not contain mycolic acid so carbon fuchsin does not penetrate its cell wall, therefore, it becomes colorless after destaining with acid alcohol.
After destaining step methylene blue is added to stain non-acid-fast bacteria blue. So if I mistakenly forgot to use methylene blue during the procedure <em>Mycobacterium smegmatis</em> will appear red due to carbon fuchsin present in their cell wall and S<em>taphylococcus aureus</em> will appear colorless because it is destained.
1. Cell starts into mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)
3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)
4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)
5. Two new molecules of DNA are created
Statements:
Adenine
Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)
DNA
Replication
Double helix
Answer;
b. nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Two conditions related to cardiac compromise are angina pectoris and myocardial infarction. In comparing the two, remember that nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Explanation;
-Angina pectoris is the chest pain or discomfort due to coronary heart disease. It occurs when the heart does not get enough blood, due to blockage or narrowing of one or more heart's arteries.
-Myocardial infarction occurs when there is decreased blood flow or stoppage to a part of the heart, resulting to the heart muscle damage.
-Nitroglycerin extended-release capsules are used to prevent chest pain (angina) in people with a cardiac compromise. However, Nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Telophase 2 is the last phase of Meiosis !!
so it consists of
3) spindle fibre starts to disappear
4) Nuclear membrane forms
5) late telophase show cytokinesis !!
so 3,4 and 5 are your answers !!
