Answer:They must be careful not to kill their host
Explanation:
As parasites cannot survive without a host, they must have evolved to be non-lethal, this is why parasites aren’t too much of a worry, if they killed their host they wouldn’t thrive.
D.) Strong nuclear force is most like electric because they are both related to distance
Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
Answer;
-Saturated fats
Explanation;
-Cholesterol is transported in the blood by different carriers. The relative amounts of cholesterol transported by each carrier can affect one’s risk for heart disease. The two major blood cholesterol carriers are LDL (low density lipoprotein) and HDL (high density lipoprotein).
-LDL cholesterol is known as “bad” blood cholesterol, and functions to deliver cholesterol to cells throughout the body and can be deposited as “plaque” on artery walls.
-Dietary fat, especially saturated and trans fats, may raise blood levels of total and LDL cholesterol. High total blood cholesterol levels and LDL cholesterol levels increase risk of heart disease.
One way to identify bacteria is using Gram Staining.

<span>The bacteria are stained with a purple dye (Crystal Violet). Though, most bacteria are then stained red. The bacteria are stained again with Potassium Iodide, then t<span>he bacteria are then washed with alcohol.
The bacteria that keep the dye after washing is known as Gram Positive bacteria. Likewise, those who don't keep the dye are Gram Negative bacteria. </span><span>The bacteria are further stained with a pink dye (Safranin). Gram Negative bacteria will go pink after this dying, whereas Gram Positive bacteria will remain purple, from the original purple dye.
Then there is </span></span><span>Ziehl-Neelsen Staining, also known as acid-fast staining. It's necessary as all mycobacteria have waxy coats on their cell walls that Gram Staining can't touch. All Mycobacteria test positive with this test, so, unfortunately, you cannot differentiate different species of Mycobacteria. </span>
