Answer:
The correct answer is option A
Explanation:
Hypoparaghyroidism occurs when thyroid gland produce little parathyroid hormone.
This is caused by:
1. Injury to the parathyroid glands during thyroid and neck surgery.
2. It is also caused by auto immune disorder. This is as a result when the body's natural defence against invading organisms starts to attack perfectly healthy tissues.
3. Congenital defects: This is as a result when infants are born without parathyroid tissue, that is ability to make thyroid glands or when the mother has hypoparathyroidism.
When a prion enters a healthy organism, it induces existing, properly folded proteins to convert into the misfolded prion form. In this way, the prion acts as a template to guide the misfolding of more proteins into prion form. In yeast, this refolding is assisted by chaperone proteins such as Hsp104. These refolded prions can then go on to convert more proteins themselves, leading to a chain reaction resulting in large amounts of the prion form.

]To calculate the amount of heat entering or leaving a system, the equation
Q
=
m
c
Δ
T
is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.

C. The vestigial structures. <span>A </span>vestigial structure<span> is an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species. Often, these vestigial structures were organs that performed some important function in the organism at one point in the past. However, as the population changed due to</span>natural selection<span>, those structures became less and less necessary until they were rendered pretty much useless. While most of these types of structures would probably disappear over many generations, some seem to keep being passed down to offspring even though they have no known function.</span>
