<h2>Maximum alleles</h2>
Explanation:
Maximum number of alleles that a person can carry is two
- A gene may have multiple alleles but a person can carry only two of those alleles because chromosomes exists in pairs
- Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent,each pair of alleles represents the genotype of a specific gene
- Gene determines a particular trait whereas alleles determines the variations in which a given trait can be expressed
- Human trait that is controlled by a gene with multiple alleles is blood group however only two of the alleles can be present in a single organism;ABO system of blood groups is controlled by three alleles, only two of which are present in an individual
One example would involve the appearance of black/white lizards in the dessert. Since the white lizards would blend in the sand, they would get eaten less allowing natural selection to favor them over the black lizards. Over time, this will create an unequal distribution of lizards as there will be many more white lizards than black.
Hope this helped :)
Facilitated diffusion is the process of moving molecules across the membrane with the help of transport proteins to make the transportation of the molecules a lot easier and smoother.
Simple diffusion, however, does not have the assistance of transport proteins. Simple diffusion takes place when molecules move from a high concentration (of said molecule) to a low concentration.
The difference: Facilitated diffusion has the help of transport proteins while simple diffusion does not.

Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))
