Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side
A gene is a section of DNA that codes for a trait or other functional product so the answer is B. gene :)))
i hope this is helpful
have a nice day
Answer:
The answer is in image see it you will get all answers.
Atoms in a molecule are said to be bonded when they share pairs of electrons with each other and this type of bonding is known as covalent bonding. When they share equal number of electrons in a pair and a full electron shell is completed, they become the most stable. But when the electrons are shared unequally by the atoms in a molecule, a POLAR COVALENT BOND is said to be shared by them. This happens as a result of two atoms sharing electron with different electronegativity i.e. the tendency to attract a shared pair of electrons.
You need to create a table like the one below and show that, if crossed, these two dogs would create 100% wire-haired dogs, but with smooth genotype. They will be heterozygous wire-haired, because the wire hair dominates over the smooth hair.

The genotype is the genes you can't see, and phenotype is what you can see. So some traits can just be in your genotype, so you don't have them but your children can get them. If there are two different traits in your genes the dominant ones will win and will be the ones you see. There needs to be two recessive genes for that gene to win. I hope this was clear. It's a little complicated!
