Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
The intervertebral discs, which are between vertebrae, are the parts that prevent the vertebrae from grinding against one another.
The intervertebrals discs act as a cushion; they absorb the stress and shockw that occur during movement, preventing such grinding.
Answer:
the mutation they are talking about deals with genes/dna
Explanation:
they show one person (j) who does not have the mutation and therefore does not have the syndrome h
then they show person (k) who has a mutation and therefore had syndrome h
look carefully at the letters on the lines. they represent the DNA in people and correlate to each other
