Atyrosine kinase receptor is different from a g-protein linked receptor in that it can trigger

a. more than onepathway at the same time.
b. when both signal moleculesare in their receptor sites, the molecules form a dimer – two molecules joined together.
c. atp is converted to adp and the phosphate groupgets attached to the tyrosine molecules.
d. the addition of the phosphate groups / relay proteinscauses a cascade of cellular responses.

a. more than one pathway at the same time.

Explanation:

Basically, RTK (receptor kinase receptor) principally activate many different transduction  pathways about 10 or more  and many cellular response in living cells.Thus,  its activates more than one signal transduction pathways at once, (compare to G-protein ), and with this mechanisms it aids in coordination of  some aspects of cell growth and cell reproduction .

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

a and c are the answeres
