Important muscle electrical signals is the movement of charged material (ions) across cellular membranes in a limited area
To know what type of transport occurred the lab and collected data are needed. As they are not present an explanation of the different transport's types, will be given.
Water, proteins, ions, and molecules of different sizes can pass through the cell membrane using different types of transports. The transport that each molecule uses depends on the concentration, size, and polarity.
We can classify the types of transport as active and passive.
Passive transport is the one that does not need energy to happen since the molecules move from a place of high concentration to a one of lower concentration. In this group, we have:
- Simple diffusion: small molecules in high concentration on one side of the membrane; move to the other side due to the difference in concentration.
- Osmosis: water passes through the membrane from a place of low concentration of molecules to one of high concentration. Water moves inside or outside the cell to valance the concentration of solutes on both sides of the membrane.
- Facilitated diffusion: uses proteins to transport large molecules, ions, or hydrophobic molecules from one side to the other. In this type of transport, we have proteins that form channels so those hydrophobic molecules can pass through the lipid membrane, and carrier proteins, which binds to a specific molecule changing their shape and transporting the molecule.
Active transport needs the<em> energy</em> to transport molecules; since it goes against the gradient's concentration. In this group, we have:
- Sodium-Potassium pump: uses ATP to move sodium outside the cell and potassium to the inside. The ions with this transport go to where they are most concentrated.
In conclusion, there are different types of transport; they depend on the concentration or type of molecule. To find out what mechanism of transport occurred in the lab, look at the components of the experiment and analyze which of these transports could be present.

Explanation:
In complete dominance, the effect of one allele in a heterozygous genotype completely masks the effect of the other. The allele that masks the other is said to be dominant to the latter, and the allele that is masked is said to be recessive to the former.
Answer:
Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process. Some of the most dangerous gases are chlorofluorocarbons, halogenated hydrocarbon, methyl bromide, and nitrous oxide.
Minimize the use of cars. The best transport options are urban, bicycle, or walking. If you use a car, try to carpool to decrease the use of cars. This prevents pollution.
Do not use cleaning products that are harmful to the environment. Many cleaning products contain substances that are corrosive. Replace these dangerous substances with non-toxic products such as vinegar or bicarbonate.
Buy local products. Not only do you get fresh products but you avoid consuming food that has traveled long distances. The more food is transported, the more nitrous oxide is produced due to the cars or trucks used to transport it.
Maintain air conditioners, as their malfunctions cause chemicals to escape into the atmosphere.
