Answer:
One-half b c sine (60 degrees)
One-half a squared sine (60 degrees)
StartFraction a b sine (60 degrees) Over 2 EndFraction
Explanation:
The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.
From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.
∴ the three options that defines the expressions that represent the are of triangle ABC are:
One-half b c sine (60 degrees)
i.e 
One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.
i.e 
StartFraction a b sine (60 degrees) Over 2 EndFraction
i.e

The parathyroid glands is group of tiny glands that is located in the neck which controls the calcium levels of the body. This gland produces parathyroid hormone (PTH). This hormone raises the blood calcium level by breaking down the bone causing the release of calcium. It also increases the ability of the body to absorb calcium from the food that we eat and it increases the ability of the kidney to hold on to calcium that would be lost in the urine later on.
The regulation of calcium levels in the body is crucial for the heart, nervous system, kidneys and bones to function normally.
Therefore, the answer is parathyroid glands.
Copy number changes is considered as genetic changes which does not lead to the formation of oncogenes.
Copy number change- The cytogenetic level of resolution, known as copy number variation (CNV), involves both duplications and deletions of sequences that generally have lengths between 1,000 base pairs and 5 megabases.
Genetic Change- Genetic mutations, which occur as our cells divide and generate duplicates of themselves, are modifications to your DNA sequence.
Base Pairs- The DNA molecule is made up of two bases (or nucleotides) that contain nitrogen. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T). These bases come in certain pairings (A with T, and G with C).
