Answer:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

Answer: Transcription factors
Explanation:
The dioxin enters the blood stream and the fat cells and liver cells store it.
While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.
The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.
This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
The correct answer is signal transduction.
Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.
There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
D. DD = 0.0225; Dd = 0.1275; dd = 0.7225
The value of Dd is different in question.
<u>Explanation:</u>
Given -
Dark colored = DD, Dd
light colored = dd
Frequency of allele D = 0.15
Frequency of allele d = 0.85
Hardy-Weinberg equilibrium is applied.
DD = 0.15 X 0.15 = 0.0225
Dd = 0.15 X 0.85 = 0.1275
dd = 0.85 X 0.85 = 0.7225
Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
