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

PLEASE HELO DOES ANYONE KNOW THE RIGHT ANSWER ??
Answer:
the last one because matter is the amount of space
The volume of a gas is 550 mL at 960 mm Hg and 200.0 C. What volume
would the pressure of the gas be 830 mm Hg if the temperature is reduced
to 150.0C? Make sure your answer is rounded to nearest whole number
and your final answer has the units of mL. *
Answer:
The volume will be 568.89 mL.
Explanation:
Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
or P * V = k
Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, the pressure of the gas is directly proportional to its temperature. Gay-Lussac's law can be expressed mathematically as follows:
[tex]\frac{P}{T}=k[/tex]
Where P = pressure, T = temperature, K = Constant
Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T}=k[/tex]
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
[tex]\frac{P*V}{T} =k[/tex]
Studying an initial state 1 and a final state 2, it is fulfilled:
[tex]\frac{P1*V1}{T1} =\frac{P2*V2}{T2}[/tex]
In this case:
P1= 960 mmHgV1= 550 mLT1= 200 C= 473 K (being 0 C=273 K)P2= 830 mmHgV2= ?T2= 150 C= 423 KReplacing:
[tex]\frac{960 mmHg*550 mL}{473K} =\frac{830 mmHg*V2}{423 K}[/tex]
Solving:
[tex]V2=\frac{423 K}{830 mmHg} *\frac{960 mmHg*550 mL}{473K}[/tex]
V2= 568.9 mL
The volume will be 568.89 mL.

convert 555 torr into kpa
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

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
PLEASE HELP QUICKLY!! How many moles of NH4OH are in 0.125L of a 1.4 M solution of NH4OH?
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
What’s the easiest way to add energy to matter
Answer:
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
Which of the following is not a force
A. Weight
B. Friction
C. Acceleration
D. Air resistance
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 resistanceIn 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?
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
