Answer/Explanation

Characteristics of Life Present in Viruses:

  • has a defined boundary - viruses are made up simply of genetic material surrounded by a<u> protein capsid </u>and sometimes a lipid membrane

Characteristics of Life Absent in Viruses:

  • made up of one or more cells - one of the main arguments for why viruses are not living is that they are <u>not cellular</u>
  • uses energy  - this is a tricky one. They don't use or produce their own energy. However, in order to reproduce they do hijack the host cells and <u>steal energy</u> from them in order to reproduce
  • exhibits growth and development - although viruses do <u>reproduce</u>, the individual viral particles do not exhibit growth or development
  • possess internal organisation - other than the fact they ahve genetic material, the inside of a virus does not contain internal organization like a cytosol, instead conssiting of the bare minimum amount of proteins to survive
  • eliminates waste - since they do not have their own metabolism, they have no waste to eliminate

A gas occupies 900.0 ML at temperatures of 27.0 Celsius. What is the volume at 123.0 celsius
Artemon [7]

Answer:

1188.0 mL.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and P are constant, and have two different values of V and T:

<em>V₁T₂ = V₂T₁ </em>

V₁ = 900 mL, T₁ = 27.0°C + 273 = 300.0 K.

V₂ = ??? mL, T₂ = 123.0°C + 273 = 396.0 K.

<em>∴ V₂ = V₁T₂/T₁ </em>= (900 mL)(396 K)/(300.0 K) = <em>1188.0 mL.</em>
