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.

Determine whether the statement is true or false, and why. “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated.”
A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
B. True
C. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This inhibits the rate of cell division decreasing it drastically.”
D. False, it should read “If a point mutation occurs in a Proto-oncogene gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Answer: A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Explanation: I already know this for a fact.
The statement “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated" is false.
What is Point mutation?Point mutation may be defined as a method of genetic alteration that is caused by the substitution of a single nucleotide for another nucleotide in the DNA sequences. In this type of mutation, a single nucleotide base is altered through insertion or deletion from the sequence of DNA or RNA.
The above statement is false because if a point mutation occurs in a tumor suppressor gene it can become inactivated which terminates the expression of suppression of tumors.
And now the cell has the capability to grow unexceptionally with an irregular pattern. This allows the rate of cell division to increase unregulated and have a most potent threat of being infected with cancers.

Answer:
false
Explanation:
The vertical zones in the ocean include the epipelagic, mesopelagic and bathypelagic zones. The zones are based on the amount of light that penetrates the ocean waters. The epipelagic zone is also called the sunlit zone because it receives enough sunlight to support photosynthesis.

Alternation of generation
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"Alternation of generation"
Alternation of generations is the type of life cycle that occurs in those plant and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.
Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.

Answer:
Explanation:
Taigas have few native plants besides conifers. The soil of the taiga has few nutrients. It can also freeze, making it difficult for many plants to take root. The larch is one of the only deciduous trees able to survive in the freezing northern taiga.

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.

Explanation:
What type of inheritance pattern shows both traits in possible offspring
Answer:
Codominance
Explanation:
Codominance is when two dominant traits are equally dominant, and therefore they both are expressed in the offspring's phenotype. For example, if in a flower, blue (BB) and red (RR) are codominant their offspring would be both red and blue. One of the common examples of codominance in humans is blood type, which is seen in AB blood since A and B are equally dominant.
