The chemical compound seen here is called methane. carbon and hydrogen are chemically combined using chemical bonds in which electrons are

Explanation:

A covalent bond is defined as the bond which is formed by sharing of electrons.

For example, atomic number of carbon is 6 and its electronic distribution is 2, 4. Whereas atomic number of hydrogen is 1.

Hence, in order to complete their octet a carbon atom needs 4 more electrons whereas a hydrogen atom needs one more electron.

Therefore, both carbon and hydrogen atom will combine together and result into the formation of that is, methane.

Therefore, we can conclude that the chemical compound seen here is called methane. Carbon and hydrogen are chemically combined using covalent chemical bonds in which electrons are shared.

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.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
