E) All of the answers are correct.
Ion channels are proteins located in the membrane that allow ions to pass through the channel pore. Ion channels can be classified (by what opens and closes the channels) into few groups:
• Voltage-gated channels-open and close in response to membrane potential
Examples: Voltage-gated proton channels, Voltage-gated sodium channels, Voltage-gated potassium channels
• Ligand-gated (neurotransmitter) or ionotropic receptors (ligand binds to extracellular domain of the receptor
Examples: "nicotinic" Acetylcholine receptor, ionotropic glutamate-gated receptors
• Lipid-gated- lipid molecules bind to the transmembrane domain of the channel
Example: Inward-rectifier potassium channels
• Light-gated channels-like rhodopsin channel that is directly opened by photons
• Mechanosensitive (e.g. stretch, pressure) ion channels.

Gregor Mendel started experiments on inheritance in the 19. century. The basis of inheritance patterns is the fact that diploid cells contain two copies of the genome and that a gene has different variants, called alleles.Alleles can be dominant (for example, marked A) and recessive (for example, marked a). In a gene locus (position of a gene) there are only two alleles, one from the mother and the other from the father.If individuals have two copies of the same allele they are homozygous (AA (dominant homozygous) or aa (recessive homozygous)). If individuals have two different alleles they are heterozygous (Aa).In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (A) are present (homozygous individuals AA) or only one copy of the dominant allele is present (heterozygous individuals Aa).In autosomal recessive traits, the phenotype is present if both copies of the recessive allele (a) are present (homozygous individuals aa).This is complicated in sex-linked trait, because there are two X cromosomes in females and one X chromosome and one Y chromosomes in males, so terms dominant and recessive are not reliable.It should also be taken into consideration that many traits are complex and caused by many genes interaction and/or environment conditions.
The answer is two identical copies of the parent cell
