The study of tree rings is called dendrochronology. Trees produce a single growth ring each year and by studying the size and composition of each ring scientists can get information about the age of the tree, available nutrients in the area, and general climatic conditions. A relatively small ring may indicate a year when there was very little rainfall and a larger ring indicates favourable conditions for plant growth.
Ice cores hold information on past global volcanic activity and past atmospheric conditions. Tiny bubbles in the ice cores give information on the concentration of gases in the atmosphere. Ice core data plays a key role in linking the increase in carbon dioxide concentrations to present day global warming.
What do the Gram stain, acid-fast stain, and endospore stain have in common?
A. used on a wet mount of the specimen
B. use heat to force the dye into cell structures
C. outcome based on cell wall differences
D. use a negative stain technique
E. are simple stains
Answer: Option C
Explanation:
The staining can be defined as a procedure which is carried out in order to make the study easy. As many of the bacterial species appear similar and are transparent so staining is done in order to see what bacterial species incorporates what color in them to make the study more easy.
Staining also depends on the type of chemicals present in the cell wall of the organism( cell wall composition). Different organisms have different staining techniques and stains by which they show color.
This ability tells alot about their characters. Like the fast stain bacteria are very hard to stain. They are mycobacterium on which normal stain do leaves any effect because of the cell wall composition. This property states that they are resistant to many of the chemicals . Likewise gram staining and endospore staining is also dependent on the type of chemical that is found in their cell wall.
