The correct answer is C. lens. Lens is a convex sealed capsule containing a clear fluid and focuses light to the back of the eye. Iris is the colored part of the eye that contracts and expands under influence of ciliary muscle. Retina is the inner surface of back of eye. Cornea is a transparent and curved surface of eye that helps to focus light.
In simple terms, Gene expression can be stated as the process by which the heredity details in a gene sequence a be made into a functional gene.
<u>Explanation:</u>
- The odd one for this question is probably would be "it occurs because of cellular signals within your body".
- It explains how a cell functions. In Gene expression, the gene encodes the protein and the message from DNA to RNA gives the cell functions.
- It is the specific combination of genes that are turned on or off. It can be stated as the process of turning off and turning on, it acts as a switch to on and off it is known as the gene expression or gene regulation.
- It creates different DNA within each of your cell types. The unique design of gene expression results in unique and different combinations of proteins and makes each cell types.
Answer:
Regulatory gene
Explanation:
Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.
However, there is need for gene expression to be regulated.
Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.
Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.
Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.

Their main function is to provide support to the plant, holding leaves, ... Meristems produce cells that quickly differentiate, or specialize,
Explanation:
Answer: This told him that the allele for a green pod is dominant to the allele for yellow pods.
Explanation: Dominant traits will express themselves even if the allele for the other trait is there. If all of the offspring were green even though they carried the allele for a yellow pod, green must be dominant.
