Using an analogy of a water balloon, describe the function of the bladder.

Answers

Answer:

A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.

Explanation:

A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.

What is bladder?

The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.

As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.

The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.

Thus the function of bladder and water balloon are found to be same.

Neutral atoms of neon with atomic
number 10 have the same number of
electrons as
a o²+
b ca²+
c​

Answers

Answer:

d. Mg²⁺

Explanation:

c. K⁺

d. Mg²⁺

Based on the Bohr's atomic model, the atom has electrons (Mass 0; Charge -1), protons (Mass 1; Charge +1) and neutrons (Mass 1; Charge 0).

The atomic number is equal to the number of protons. That means there are 10 protons. As the Neon is netural, the amount of electrons must be 10.

A neutral atom of Mg has 12 electrons, that means the Mg²⁺ has 10 electrons the same than Ne.

Right option is:

d. Mg²⁺

Answer:

M = 0.47

Explanation:

1 - Turn grams to moles using molar mass:

16g NaOH × 1 mol NaOH / 40g NaOH = 0.4 mol NaOH

2- Turn milliliters to liters:

855mL × 1 L / 1000mL = 0.86 L

3- Use formula which is M = moles of solute / liters of solvent:

M = 0.4 mol NaOH / 0.86 L = 0.47

convert 555 torr into kpa

Answers

Answer:

73.97 kPa

Explanation:

It's helpful to know the conversion factors and apply them.

First, convert from torr to atm:

555 torr ÷ 760 atm = 0.730 atm

Next, convert from atm to Pa:

0.730 atm × 101,325 Pa = 73967 Pa

Finally, convert to kPa (1000 Pa in 1 kPa):

73967 Pa ÷ 1000 kPa = 73.97 kPa

PLEASE HELP QUICKLY!! How many moles of NH4OH are in 0.125L of a 1.4 M solution of NH4OH?

Answers

Answer:

0.175mol

Explanation:

Molarity of a solution can be calculated thus:

Molarity (M) = number of moles (n) / volume (V)

According to the information provided in this question, volume of NH4OH = 0.125L, molarity = 1.4M

Using; Molarity = n/V

1.4 = n/0.125

n = 0.175mol

Which of the following is not a force
A. Weight
B. Friction
C. Acceleration
D. Air resistance

Answers

Answer:

Acceleration

Explanation:

Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.

The answer option which is not a force is: C. Acceleration.

What is a force?

A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

The examples of a force.

In Science, the three (3) most common examples of a force include the following:

WeightFrictionAir resistance

In conclusion, acceleration is not an example of a force but a change in the rate of velocity of an object with respect to time.

How many liters of carbon monoxide are needed to react with 32.65 g oxygen gas to produce carbon dioxide?

Answers

Answer:

2.040 mol CO

Explanation:

First, write out your reaction:

CO + O2 --> CO2

Balance the reaction:

2CO + O2 --> 2CO2

Now divide the 32.65 g O2 by the molar mass of O2 (32.00 g/mol) to get moles of O2. Then multiply by the mole ratio of 2 mol CO for every 1 mol O2 to get moles of CO needed to fully react.

32.65 g O2 / 32.00 g/mol = 1.020 mol O2

1.020 mol O2 • 2 mol CO / 1 mol O2 = 2.040 mol CO

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000
