Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.

Explanation:
Cartilage and Bone are specialized forms of connective tissue.
They are both made up of cells embedded in an extracellular matrix.
It is the nature of the matrix that defines the properties of these connective tissues.
Cartilage is thin, avascular, flexible and resistant to compressive forces.
Bone is highly vascularized, and its calcified matrix makes it very strong.
True, This is because they they reproduced itself by spores called Sori so therefore they do grow underground stem
Offspring will be heterozygous expressing the dominant trait.
Hope this helps.
