Answer:
b. thick wall.
Explanation:
Endospore is a structure formed by some bacteria, that help them survive unfavourable conditions (e.g. lack of nutrients). This survival strategy of some bacteria (usually Gram+ bacteria) help them stay dormant for a while, until stressful conditions stop. A thick wall composed of many layers (exosporium, spore coat, spore cortex, core wall) of the endospore is what provides resistance to different stressful chemical and physical factors such as UV radiation, temperature, chemical damage etc.

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.
The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.
Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
Answer:
b.Their cell walls have very different biochemical properties.
Explanation:
Cellulose is a homopolysaccharide of glucose residues and is the main chemical component of the cell walls of the plant cells. The glucose residues in cellulose are linked together by beta 1-4 glycosidic bonds. Chitin is a linear homopolysaccharide of glucose residues and is the main structural component of the fungal cell wall. On the other hand, peptidoglycan is the major structural component of the bacterial cell walls. Peptidoglycan is a heteropolysaccharide of two different residues. These are N-acetylglucosamine and N-acetylmuramic acid. Therefore, the chemical components and that make the cell walls in plants, fungi and bacteria differ significantly from each other imparting them distinct chemical features.
