Which is a non-Mendelian trait?
A. A trait controlled by many genes
B. A trait with a clearly dominant form
C. A trait controlled by one gene
D. A trait with two alleles
Answer:
The answer would be A.
Explanation:
Non-Mendelian traits are traits that are not passed down with dominant and recessive alleles from one gene. Examples of polygenic traits are hair color and height. ... Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
A non-Mendelian trait would be a trait that is controlled by many genes. The right option would be A.
Mendelian traits are traits that obey the principles of the Mendelian laws While non-Mendelian traits simply do not conform with the principles and laws of Mendel.
A trait that is Mendelian would have the following:
Show simple dominance or recessive formControlled by a single geneEach gene must have 2 alleles. The 2 alleles can be the same (homzygous) or different (heterozygous).Thus, a trait that is controlled by many genes is clearly a non-Mendelian trait.

Compare and contrast passive transport, active transport, and osmosis
Answer:
Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.
Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.

DNA replication is a process that involves copying the DNA molecule if a single base was miscopied what would be a possible result of this for the cell in which it happened
Answer:
If a single base is miscopied during replication then there is a possibility that the new base which has been incorporated will specify the same amino acid just like the old base. It happens because genetic code is degenerate which means that more than one codon can specify same amino acid.
