consider the cell structure that is shown below.

a cell structure is shown. this structure consists of phospholipid bilayer, proteins, and carbohydrates.

which is a function of the structure that is represented in the image?
controls the movement of substances into and out of cells
builds proteins from amino acids
in determining plant cell shape
provides support and protection

The correct option is A) controls the movement of substances into and out of cells

Explanation:

As the description tells that the structure is a phospholipid bilayer, one can easily predict that the structure is a plasma membrane. A plasma membrane consists of lipid tail and phosphorus heads. As lipids are hydrophobic they are embedded inwards between the phosphate heads. The plasma membrane also consists of proteins and carbohydrates embedded in its structure. The proteins also facilitate the movement of molecules inside the cell.

The function of the plasma membrane is to allow and control the movement of molecules inside and outside of a cell.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
