Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
Answer:
They started to melt
Explanation:
depending on the temperature outside and the length of time they were exposed to the sun they would begin to melt
Answer:speciation
Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another these are allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
Answer:

The natural history approach of Darwin and his predecessors gradually evolved into the twin sciences of animal ecology, the study of the interactions between an animal and its environment, and ethology, the biological study of animal behaviour.
