Answer:
C) Mutations
Hope this helps :)
B) be evaluated through experimentation
C) a be refined after evolution
D) acts as a universal principle
D) acts as a universal principle
It's D because a hypothesis is just an educated guess(sort of) of what you think happens. A universal principle is the exact opposite of that.
3. Denature and decrease its activity
Changes in pH can affect the activity of enzymes. Enzymes have an optimal pH which they function most efficiently, and changes from this pH can cause denaturation of the enzyme. An important aspect of molecular biology is that structure means function. Denaturation affects structure of the enzyme and therefore, function. A pH that is too acidic or basic can disrupt the ionic and hydrogen bonds that maintain the 3D structure. This denaturation results in a loss of enzyme activity rather than increase.
B)speciation
C)convergent selection
D)stabilizing selection
Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.

A. The wave will speed up.
B. The wave will get completely absorbed.
C. The wave will change in frequency.
Answer: A
Explanation:
Answer:
The wave will change in frequency.
Explanation:
As a way to keep motion it should reflect enough to change frequency.
