In the 1700s, organisms were broken into only two kingdoms - Animalia and Vegetabilia. Throughout the next few hundred years, the name Plantae replaced Vegetabilia, and other kingdoms began to emerge. Finally, in the 1900s, the currently accepted six kingdom system was adopted.

Currently, the kingdoms include: Plantae, Animalia, Fungi, Protista, Archaebacteria, and Eubacteria.

The development of the current classification system is probably due to .
A.
the discovery of differences between organisms
B.
the discovery of new organisms
C.
the invention of new technology and scientific techniques
D.
all of these

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
