The bone tissue contains many small pauses this is most likely caused by osteoporosis.

Osteoporosis is a health condition that weakens bones, making them fragile and more likely to break.

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture.

Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.

Bone is living tissue that is constantly being broken down and replaced.

Hence, the bone tissue contains many small pauses this is most likely caused by osteoporosis.

Answer:

The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume

I hope this helps ^^

Answer:

The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m—about 100,000 times smaller.

True, the metric system is now known as the international system of units.

A system of measurement in which the basic units are the meter, the second, and the kilogram.

The Metric System is also known as The International System of Units. The metric system is called that because it is the system that the vast majority of countries in the world currently use.

The only countries that do not use this system are Liberia, Myanmar, and the United States, although schools in the United States are working to teach students both variations.

Second Ionization energy is required to move from  Ca⁺ to Ca²⁺ + e⁻. Hence, option D is correct.

First ionization energy: The energy needed to remove the outermost, or highest energy, an electron from a neutral atom in the gas phase.

An element's second ionization energy is the energy required to remove the outermost, or least bound, an electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first.

Let us write the reaction equation properly:

                 Ca⁺ → Ca²⁺ + e⁻

In the reaction above, we see that calcium goes from a single charge to being doubly charged by losing an electron.

Different atoms bind their valence electrons with different amounts of energy. We must supply enough energy to remove the most loosely held electrons in an atom. This amount of energy required is called ionization energy.

The first ionization energy removes the outermost electron and makes the atom to become an ion.

Hence, option D is correct.

The volume of 1.6 M NaHCO₃ must be poured on the spill to react completely with the sulfuric acid is 323.75 milliliters

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is defined as the moles of a solute per liters of a solution.

Molarity is also known as the molar concentration of a solution.

Let's find out the number of moles of H₂SO₄ in 81 ml of 3.2 M H₂SO₄

Number of Moles = Volume (ltr) X Molarity

                              = 0.081 x 3.2 = 0.259 mol H₂SO₄

According to the question given, balanced chemical equation ;

H₂SO₄+ 2NaHCO₃ --> Na₂SO₄ + 2CO₂ + 2H₂O

From the balanced equation -

1 mol H₂SO₄ reacts with 2 mol of NaHCO₃

Therefore,

0.259 mol H₂SO₄ reacts with X mol of NaHCO₃

X = 0.259 x 2 mol = 0.518 moles of NaHCO₃

we know,

Number of mole = Volume x Molarity

For NaHCO₃ ;

0.518 = V x 1.6

V = 0.323 ltr

V = 323.75 mL NaHCO₃

Hence, 323.75  milliliters of 1.6 M NaHCO₃ must be poured on the spill to react completely with the sulfuric acid.

The volume of the person's lungs if the temperature rises from 36°C to 39°C is 3.53L and will likely not explode.

The volume of a substance can be calculated using the following formula:

V1/T1 = V2/T2

Where;

3.5/309 = V2/312

309V2 = 1092

V2 = 1092 ÷ 309

V2 = 3.53L

Therefore, the volume of the person's lungs if the temperature rises from 36°C to 39°C is 3.53L and will not explode.

The volume of 1.0 g of nitrogen in a balloon is increased. It causes: the mass of the gas to decrease the density of the gas to increase and the pressure of the gas to decrease the temperature of the gas decrease.

How much space an object or substance takes up.

If you increase the temperature of the gas in the balloon, the pressure will initially increase.  The balloon will expand until the pressure inside drops back down and is equal to the pressure outside.

If you increase the atmospheric pressure, the balloon will compress until the pressure inside equals the new pressure outside.

If you remove gas from the balloon, the pressure will drop, causing the balloon to compress until the pressure is again equal to the pressure outside.

if you place the balloon underwater, it will be under greater pressure, causing the balloon to compress until the inside pressure equals the new outside pressure.
