Answer:
Because of the chemical and structural nature of the phospholipid lipid by layer the lipid soluble molecule can just pass the lipid membrane and some small molecules can also pass freely.
Explanation:
as we know that the homeostasis is an important process for a living cell to maintain it self so for the the exchange of materials between the external and internal environment is must so for that it exchange material with the outside environment of the cell.as the cell membrane is semipermeable(mean allow some molecule to pass(lipid soluble) and not others(lipid non soluble) to pass through the membrane.the cell membrane is selectively permeable due to its nature and chemical composition the chemical composition is lipid and phosphate and glycerol(head) with fatty acid that may b saturated or unsaturated(tail).so finally all those molecule which are polar can not pass through the membrane and non polar can pass the membrane.The size of the molecule is also a factor on which the permeability depends.
Answer:
sodium ions diffuse through leakage channels into the cell, but potassium ions diffuse through leakage channels out of the cell
Explanation:
Answer:
forward; reverse
Explanation:
Chemical equilibrium is a state where there is no tendency to change; the situation is stable.
This occurs when the reaction rate of the forward reaction is equal to the reaction rate of the reverse reaction. This is because when no rate is greater than another, the situation will remain the same.

Two chromosomes in a pair – normally one inherited from the mother and one from the father. For example, the two copies of Chromosome 1 in a cell would be referred to as homologous chromosomes.
Yes they are vascular like other gymnosperms
