Answer: The type of deformation in which the object permanently changes size and shape without fracturing is called ductile deformation.
Explanation:
Ductile deformation is when the object bend or flow without fracturing like clay.
On the other hand, when the object breaks is considered brittle deformation.
Answer:
A. There must be a change in chemical properties.
At least 2 or 3 atoms must change for it to be considered chemical. There must be some type of reactants that will change this. Otherwise, it's not a chemical reaction.

A radioactive half-life talks about the amount of time
it takes for half of the original isotope to deteriorate.
The solution for this problem is:
Half-life (lst order
reaction) = ln2 over k <span>
<span>so half-life = .693 over 3.25 = .213 day is the
half-life for the metabolism reaction</span></span>

Answer:
D
Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.
