Multiply by the power of the eyepiece, usually 10x.
Large crystals indicate that it cooled very quickly. If it cooled slowly, it would have time to settle down and make a nice smooth rock.
Answer:
D. Opposite
Explanation:
The rocket engines lift a rocket from the earth because hot gases with high velocity .react against rocket and push it up.
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:
Forensic anthropologists.
Explanation:
Only one sickle attracted blowflies to the trace amount of blood hidden to the naked eye which resulted in the confession by the murderer.” Several decades later, forensic entomology made its way into the courthouse; today, police detectives, coroners, federal agencies, and medical examiners work closely with forensic
