All of the offspring produced in a test cross involving a brown rabbit and a white rabbit are brown. The result of this cross is best explained by A. Incomplete dominance B. Codominance C. Crossing over D. Dominance
Answer:
D
Explanation:
The result of the cross is best explained by dominance.
According to Mendel, when the alleles that make up a gene are different and one of the alleles is dominant over the other, the dominant allele would mask the effects of the recessive allele.
In the same vein, when the alternate version of the same trait is dominant, such trait would be expressed over the other version in heterozygous state.
Assuming that the genotype of the brown rabbit is BB and that of the white is bb. When the two rabbits are crossed:
BB x bb
Bb Bb Bb Bb
All the offspring would be heterozygous and brown in color because the brown allele is dominant over the white allele.
Hence, the correct option is D.

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.
Hope this helped :)

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.

In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
In order for protein synthesis to occur, both transcription and translation must occur. Which of the following statements describes the difference between transcription and translation?
In transcription, the genetic code of a DNA molecule is encoded. Translation is the process of converting the DNA code into a code that RNA can use.
In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.
In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.
Answer:
1
Explanation:
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. The translation is the process of creating an amino acid chain by using the encoded messenger RNA. So the correct option is D.
What are transcription and translation?The first step in the process of gene expression is called transcription. In this process, the DNA sequence of a gene is copied for the formation of an RNA molecule.
RNA polymerase enzymes link the nucleotides of DNA to form an RNA strand. The DNA strand is the template. For every gene in the genome, transcription is separately controlled.
The translation is the process by which an mRNA molecule encodes for a protein. The process of translation happens with the help of tRNA in the ribosomes.
Translation requires ATP which is produced by the tRNA. The tRNA in the ribosomes supplies energy to RNA for the transcription of proteins The entry of mRNA occurs by the smaller subunit of RNA and the amino acid chain extends from the larger subunit.
Therefore the correct option is D.

During replication, enzymes called ____________________ untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the _______________________.
Answer:
During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.
Explanation:
Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.
For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.
The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.
The study of genes is called genetics.

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.
