The answer to your question is false
The answer is Parathyroid Hormone (PTH). Steroids reduce calcium
levels in the blood. This results in activation of the parathyroid hormone that
is essential in the metabolism of calcium
in the blood. PTH induces reabsorption of
calcium from bones to restore homeostasis
Ca2+ levels in the blood hence causing
osteoporosis. Osteoporosis causes an increased risk of bone fractures.
By using the equation F=ma (Force = Mass*acceleration), the answer is 15,100 N for the first one and 1.25 m/s^2 for the second.

Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
The probability that the child will not inherit Huntington’s disease is therefore 1/4.
<h3>What is Probability?</h3>
This is defined as a numerical description of how an event is likely to occur and the formula is :
Number of favourable outcomes/Total Number of outcomes.
When the heterozygous traits(Hh × Hh) are crossed, we have HH, Hh, Hh, hh.
The recessive trait is hh which makes the probability to be 1/4 in which the resulting child will not inherit the disease.
