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

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.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
