Permeability is the condition of
being capable of having materials flow into and out of a membrane. The
permeability of a cell membrane is determined by how easily a molecule can diffuse across the membrane. Usually,
only molecules that are fat-soluble can permeate across a cell membrane. This
is because the layer that is exposed on the linings of the cell membrane is
nonpolar and can therefore allow the fat-soluble molecule to pass through.
Answer:
may be egg shaped or may be spiral shaped has no recognizable shape has no new stars being formed has almost no gas or dust between stars.
Assuming you are asking about some sort of oscillation, the magnitude of the net force is maximum where the acceleration of the object is the largest. The velocity of an object is maximum where the acceleration is zero.
Answer:
To use them in future projects and saving the community.
Explanation:
An explanation about using them in future projects is that you can, for example, use plastic for a biology project. It's also a proven fact that recycling can help the environment so there will be less pollution due to having certain recyclables in the wrong places such as the ocean.
Answer:
It remains constant
Explanation:
As we know that buoyant force on an object given as
Fb = ρ Vd g
ρ= Density of fluid
Vd=Volume displace by body
g=10 m/s²
Fb =buoyant force
So from above we can say that buoyant force does not depends on the depth. It only depends on the fluid density and volume displace by body.
So when rock gets deeper and deeper the buoyant force will remain constant.
It remains constant
