Prions A prion is a type of protein that can infect both people and animals by causing the brain's typically healthy proteins to fold improperly. Since prion are only proteins without any genetic material, their manner of action is very different from those of bacteria and viruses.
A prion is a type of protein that can infect both people and animals by causing the brain's typically healthy proteins to fold improperly.
Since prion are only proteins without any genetic material, their manner of action is very different from those of bacteria and viruses. Correctly folded proteins are changed into the disease-associated form once a misfolded prion enters a healthy person, possibly through the consumption of infected food. Nobody is exactly sure how this occurs as of yet.

Answer:
C. Scares away predators
Explanation:
it scares them away so the predators dont eat them
Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = 
= -0.25
a = -0.25 m/
The deceleration of the plane is 0.25 m/.
The biosphere is everything. the whole planet. so all of the above is right
