Answer:
True is the correct answer.
Explanation:
- The statement that a prion is an infectious, self-reproducing protein structure is true.
- prion is an infectious particle and they do not have genetic material.
- Prion present in the brain region that results in deadly neurodegenerative illnesses in humans and animals.
- Prions are the self-producing proteinaceous infectious capable of transferring infection in the absence of the nucleic acids.
- prions enter in the brain by an infection and they emerge from the variation in the gene that encodes the protein and once the prions present in the brain multiply by causing the benign proteins to refold into an abnormal form.
<span>Boyle's Law is k = PV so
Initial k = 13.0 L x 4.0 atm = 52 L atm
Final kf = 6.5 L x 8 atm = 52 L atm
The gas obeys Boyle's Law
The answer with two significant figures separated by a comma is k = 52, kf = 52.</span>
this is the answer is
Zn<span> + </span>HCl<span> = </span>ZnCl2<span> + </span>H2 <span> </span>
