A 12 pound shot put and a small metal BB are dropped from a tall tower, inside a vacuum chamber,
hichkok12 [17]

Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.

<h3>What affects the speeds at which these objects fall?</h3>
  • The falling speeds in both air and a vacuum will be the same for both objects.
  • This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
  • The same will occur in water if and only if the densities of the two objects are equal.

Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

Why are lipids and proteins free to move laterally in membranes?
Rashid [163]

Correct option C) Hydrophilic portions of the lipids are in the interior of the membrane.

Lipids and proteins free to move laterally in membranes because both are inserted into a fluid lipid bi-layer and they are able to diffuse laterally through the membrane.

Lipid Composition of Cell Membranes is a important property of lipid bilayers which is behave as two-dimensional fluids where individual molecules are rotate and move freely in lateral directions

Membrane proteins and phospholipids both are unable to move back and forth between the inner and outer leaflets of the membrane at an appreciable rate. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or undergo transverse movement between bilayers.
