Answer:
The correct answer is A.
Explanation:
An osteoclast is large multinucleated cell present in the bone. Its main function is bone resorption, which occur when the osteoclasts secret hydrogen ions and many enzymes. As a result, bone matrix is digested by them. The most important enzyme is the protease cathepsin K, which degrades collagen.
Cathepsin K is regulated by parathormone, calcitonin and growth factor interleukin 6.
Matrix digestion is key during <u>bone fractures</u>, because it allows the repair and remodeling of the bone. But when this action is excessive, it can lead to osteoporosis (loss of bone density).
I took bio last year and I remember something about how many amino acids there are and I think it’s about thirty or so

Answer:
1. 1.26823082 mL
2. 0.5 g/mL
Explanation:
The density formula is:
1.
Rearrange the density formula for v,
<em>Multiply both sides by v.</em>
<em>Divide both sides by d.</em>
Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.
Substitute the values into the formula.
Divide. Note the grams, g, will cancel.
2.
Use the density formula.
Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.
Substitute the values into the formula.
Divide.
one of the most important rain forest predators, attacking a wide range of different primates, is the monkey-eating eagle. we know this because all forest primates have an identical alarm call that means, essentially, "Eagle!"
<h3>What are primates?</h3>
Primates are those forest animals that has highly developed brain and backbone.
Some of them are predators while others are source of food for predators known as preys.
Example of such predators are the monkey eating eagles which are capable of hunting monkeys as their preys.

This question “How fast can light travel” is considered as an good scientific question because it helps inform for other experiment.
Answer: Option D
<u>Explanation:</u>
The speed of light is a universal physical constant and it is found to be and it is important to determine various physical units such as electromagnetic wave propagation, e.g., optics, radio waves.
This light constant is majorly used in many of the experiments and hence it is very much helpful in determining values required in an experiment. Thus the measurement of the light speed can help us inform other experiments, so we can conclude option D as correct answer.
