Why do lipids make effective cell membranes in living cells?

Chemistry
2 answers:
Vaselesa [24]3 years ago
4 0

The answer is the second option. Lipids make effective cell membranes in living cells because lipids (fats) are not soluble in water. This means that lipids and water do not mix... This lipid bilayer helps to protect the cell.

They form barriers so the second option is right because lipids are hydrophobic meaning they don’t mix with water

The pressure of 1 mol of gas is decreased to 0.5 atm at 273 K. What happens to the molar volume of the gas under these condition
m_a_m_a [10]

Answer : The molar volume of the gas will be, 44.82 L

Solution :

Using ideal gas equation,

PV=nRT

where,

n = number of moles of gas  = 1 mole

P = pressure of the gas = 0.5 atm

T = temperature of the gas = 273 K

R = gas constant = 0.0821 Latm/moleK

V = volume of the gas.

Now put all the given values in the above equation, we get the molar volume of the gas.

(0.5atm)\times V=(1mole)\times (0.0821Latm/moleK)\times (273K)

V=44.82L

Therefore, the molar volume of the gas will be, 44.82 L

False

Explanation:

Compounds are chemically combined

lemonade is not

If the squeezed lemonade is made by squeezing lemons to extract the juice and mixing it with water and sugar, it would be a homogenous mixture.

If it contains a pulp than it would be heterogeneous

How does scarcity impact society
g100num [7]

Answer:

a market/society is dictated by supply and demand and scarify affects the supply of a product because if something is more scarce/rare then usually there is a higher demand and a higher price. This impacts society because it affects the price of things and how much people are willing to give for it
