Changes in global temperature and other blank conditions have effects on organisms and on the blades to which they belong. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a blank pattern

Environmental conditions

macroevolutionary

Explanation:

Environmental conditions has a great affect on the survival, growth and development of organisms. If the environmental conditions are suitable for the organism so it will increase in population while on the other hand, if the environmental conditions are against the organisms so the organisms extinct from that region. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a macroevolutionary pattern. Macroevolution is defined as the evolution of groups larger than an individual species.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
