B is the answer! Hope this helps :)
Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase
Here is a word equation for the hydrolysis of lactose:
lactose + water → galactose + glucose
Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
Answer:
c. organisms are better adapted to an environment.
Explanation:
With natural selection the parent gives of a gene that is better suited for survival in an environment.
Viruses are not always classified as living cells because they cannot live independently. They rely on a host to provide all resources to live, without a host they are in a dormant, near dead like state. Therefore it has to define a virus as dead or alive as it may or may not have a host.
