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.
Answer:
b. Conducts electricity when dissolved in water
Explanation:
Iron(II) chloride, is the chemical compound with formula FeCl2.
It is a solid with a high melting point of about 677 degree Celsius or 950 K when in anhydrous form but have lower melting point in hydrated form.
The compound is often off-white. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in the laboratory.
There is also a dihydrate. The compound is highly soluble in water, giving pale green solutions.
