This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.
Explanation:
The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.
A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.
A solution having lower concentration of solute than the cell cytoplasm is called the hypotonic solution.
The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.
A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.
A cell placed in hypotonic solution will undergo endosmosis of water so it will gain water and its mass will increase.
A: Population
If a group of one certain species are living in the same area they are a population. The same goes for humans, we are the same species and when we live in the same area we say we are part of a population. That’s why you would hear things like “the population of massachusetts is 2million” or whatever it is.
In the simulation, neon and argon have particles that are single atoms. On the other hand, each particle of oxygen is made of two atoms of the same kind. Hope this helps
Answer:
Hydrogen Bonds
Explanation:
The arrangement of phospholipid bilayer of plasma membrane is such that ; the polar phospholipid heads point outwards into the watery external environments. This Polar environment is Hydrophilic or water loving, while the water- hating hydrophobic tail region pointed inwards away from the watery medium.
This gives the usual bilayer shape to the plasma membrane,with the tail facing one another and heads outward.
The hydrogen bond is formed as inter molecular forces between the hydrogen atom (positive side)of water molecule and oxygen atom (negative side)of the polar molecules e.g glucose, to form an idea dipole -dipole force interactions,
Polar Compounds, glucose, urea dissolved easily in hyrophilic watery environment to from Hydrogen bonds with water
<u>The correct answer is Hydrogen bond a dipole dipole force</u>
