why a multicellular organism needs specialized cells to survive
Answer:
Cells function differently in unicellular and multicellular organisms. A unicellular organism depends upon just one cell for all of its functions while a multicellular organism has cells specialized to perform different functions that collectively support the organism.

What is the molarity of a solution prepared by dissolving 8 grams of BaCl2 in enough water to make a 450. 0 mL solution? (Hint: must convert grams to moles first).
Molarity is the molar concentration of the solute dissolved in a volume of a solution. The molarity of the solution prepared by dissolving barium chloride will be 0.085 M.
What is molarity?Molarity is the ratio of the moles of the solute to that of the volume of the solution in Liters. It can be given as,
[tex]\rm Molarity = \dfrac{moles}{Volume}[/tex]
Here, moles of the barium chloride can be given by the mass and the molar mass and volume is given as 0.450 L.
Substituting values in the equation:
[tex]\begin{aligned}\rm Molarity &= \rm \dfrac{mass}{Molar \;mass\times Volume}\\\\&= \dfrac{8}{208.23\times 0.450}\\\\&= 0.085\;\rm M\end{aligned}[/tex]
Therefore, 0.085 M barium chloride is the molar concentration.

Nitrogen gas at 20. °c in a balloon has a volume of 3.0 l and pressure of 1.5 atm. if the temperature of the balloon is increased to 30. °c and the pressure to 2.5 atm, what is the new volume of the balloon? use the formula: p1v1 t1 = p2v2 t2 temperature conversion: °c 273 k
The new volume of the balloon which was initially 3 L is 1.86 L
Data obtained from the question Initial temperature (T₁) = 20 °C = 20 + 273 = 293 KInitial volume (V₁) = 3 L Initial pressure (P₁) = 1.5 atm New temperature (T₂) = 30 °C = 30 + 273 = 303 KNew pressure (P₂) = 2.5 atmNew volume (V₂) =? How to determine the new volumeThe new volume of the balloon can be obtained by using the combined gas equation as illustrated below:
P₁V₁ / T₁ = P₂V₂ / T₂
(1.5 × 3) / 293 = (2.5 × V₂) / 303
Cross multiply
293 × 2.5 × V₂ = 1.5 × 3 × 303
732.5 × V₂ = 1363.5
Divide both side by 732.5
V₂ = 1363.5 / 732.5
V₂ = 1.86 L

A 10,0-L cylinder of gas is stored at room temperature (20.0°C) and a pressure of 1800 psi. If the gas is
transferred to a 6.0-L cylinder, at what temperature in CELCIUS would it have to be stored in order for the
pressure to remain at 1800 psí? Reminder, convert your temperature to Kelvin before you begin the problem.
(Please put units)
Considering the Charles' law, the gas would have a temperature of -109.2 C.
Charles' lawFinally, Charles' law establishes the relationship between the volume and temperature of a gas sample at constant pressure. This law says that the volume is directly proportional to the temperature of the gas. That is, if the temperature increases, the volume of the gas increases, while if the temperature of the gas decreases, the volume decreases.
Charles' law is expressed mathematically as:
[tex]\frac{V}{T} =k[/tex]
If you want to study two different states, an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
Temperature of the gas in this caseIn this case, you know:
P1= 1800 psiV1= 10 LT1= 20 C= 293 K (being 0 C= 273 K)P2= 1800 psiV2= 6 LT2= ?You can see that the pressure remains constant, so you can apply Charles's law.
Replacing in the Charles's law:
[tex]\frac{10 L}{293 K} =\frac{6 L}{T2}[/tex]
Solving:
[tex]\frac{10 L}{293 K} T2=6 L[/tex]
[tex]T2=\frac{6 L}{\frac{10 L}{293 K} }[/tex]
T2=163.8 K= -109.2 C
The gas would have a temperature of -109.2 C.

I am very bad :(
1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)

If you had 0.2M solutions of nitric and carbonic acids, which solution would have a lower pH?
Why?
0.2 M each of nitric acid and carbonic acid will have the same pH.
pHThe pH of substances is mathematically given as:
pH - -log [H+]
Nitric and carbonic acid dissociates according to the following:
HNO3 ---------> H+ + NO3-
H2CO3 -------> H+ + HCO3-
Thus, both acids ionizes to produce the same number of moles of H+, thus, producing the same pH
