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.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
