Answer:

Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.

Why amylose doesn't form a gel when hot water is added? can someone explain

Jet001 [13]

Amylose is less soluble in water. It does not form a gel when hot water is added. Amylose constitutes about 20-30% of the starch. Amylose can be hydrolyzed with α amylase and β amylase enzymes completely.

Triangle ABC is an equilateral triangle with side lengths labeled a, b, and c. Triangle A B C is an equilateral triangle. The le

kirill115 [55]

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 $\frac{1}{2}bcsin60^{0}$

One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.

i.e $\frac{1}{2}a^{2}sin60^{0}$

StartFraction a b sine (60 degrees) Over 2 EndFraction

i.e $\frac{absin60^{0}}{2}$
