Which hormones help build bones?

Answers

Answer 1

Answer: Hormones are really important to bone strength. Hormones are chemicals made by glands that travel throughout the body and have many effects on growth, maturation, energy, weight, and bone strength. Sex hormones (estrogen made in the ovary of females and testosterone made by the testes in males) control ability to reproduce. They also are a major reason that bone strength increases in the early teenage years. When teenagers have low estrogen or testosterone levels, the bone becomes weaker.

Answer 2

Other hormones come from the thyroid gland, the parathyroid gland, the pituitary gland near the brain, and the brain itself. These hormones control levels of calcium in the blood, energy levels, and ability to grow. They act the same in boys and in girls. Healthy bones need the correct levels of all of these hormones. There are many reasons these hormones can be too high or low, but fortunately they are all uncommon.

Most of these hormones do not become abnormal because of things we can do. Estrogen and testosterone, however, depend on normal body weight. If teenagers do not get enough nutrition and become too thin, then the hormone levels will be too low. The parathryoid hormone also responds to nutrition. Too little calcium causes parathyroid hormone to increase and that will dissolve some of the bone.

How many liters are equivalent to 500 centiliters

Answers

1000 centiliters = 1 liter.

500 centiliters = x liter

1000 / 500 = 1/x Cross multiply

1000x = 500 Divide by 1000

x = 500/1000

x = 1/2

500 centiliters = 1/2 or 0.5 of a liter.

For the conversion process, 500 centiliters is equivalent to 5 liters.

How to do conversions?

Centiliters (cL) and liters (L) are both units of volume. Centiliters are a smaller unit, while liters are a larger unit. To convert from centiliters to liters, use the conversion factor of 100 centiliters per 1 liter.

In the given scenario, there is 500 centiliters. To convert this to liters, divide the number of centiliters by 100. This division accounts for the fact that there are 100 centiliters in 1 liter.

Given:

500 centiliters (cL)

To convert 500 centiliters to liters:

500 cL ÷ 100 = 5 liters

Therefore, 500 centiliters is equivalent to 5 liters.

Adam's dad takes the parkway to work. It takes him 45 minutes to travel from mile marker 145 where he enters the parkway to his exit at mile marker 98. What is his average speed?1. 62.7 mph

2. 47 mph

3. 1 mph

4. 193.3 mph

Answers

speed=distance/time

see his distance

distance is from 145 to 98
145-98=47 miles

time
60 mins per hour
45 mins =time
time=45/60 hours=0.75 hours

47 miles per 0.75 hours
47/0.75=62.6666666 mph

If atoms are made up of smaller particles, such as protons, neutrons, and electrons, then why are atoms considered the smallest particles of an element?

Answers

Because all protons are the same, all neutrons are the same, and all electrons are the same, and all atoms of all elements are made of them, so the smallest particles of every element are the same particles. It's only when some number of them get together and make an atom that the properties of an element begin to show up.

Let me try it like this, and see if this does anything for you:

All buildings are made of brick, cement, wood, glass, pipes, wires, etc.
But all bricks are the same, all cement is the same, all glass is the same, etc.
Houses, stores, shacks, skyscrapers, and hunting lodges are all made of them.
You don't know what kind of building you have, until some brick, some cement,
some wood and some glass all get put together.

Similarly, you don't know what kind of atom ... of what element ...you have, until
some protons, some neutrons, and some electrons get put together

A spring (k = 20 N/m) sits on a frictionless surface. The spring is compressed 20 cm and a 2 kg mass is placed before the spring and released from rest. How much time passes between the time that the mass is at the point x = 0 m and x = 2.0 m? A.) 4.34s B.) 1.42s C.) 2.48s D.)0.23s E.)none of the above

Answers

Answer:

E.)none of the above

Explanation:

Elastic energy = kinetic energy

½ kx² = ½ mv²

v = x √(k / m)

v = 0.2 m √(20 N/m / 2 kg)

v = 0.632 m/s

Time to travel 2.0 m:

t = (2.0 m) / (0.632 m/s)

t = 3.16 s
