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.
I believe mutation will make a population have more genetic variation. Genetic variation describes naturally occurring genetic differences among individuals of the same species. It is the difference in DNA sequences between individuals within a population. Variation permits flexibility and survival of a population in the face of changing environmental circumstances. It is considered an advantage, as it is a form of preparation for the unexpected.
Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
A mutation is a long-lasting alteration to the DNA's nucleotide sequence that can occur during replication and/or recombination. Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.
Different Mutations
Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
1. Base Replacements
Point mutations are single nucleotide replacements; you may recall the point mutation Glu ——-> Val is the culprit of sickle cell anemia. There are two types of point mutations, the most prevalent of which are.
Transition and Transversion.

#SPJ4
Density tells you the mass of exactly one unit of volume any given substance.
The answer is C. 13.6
B. Frost wedging.
This occurs in places where temperatures frequently rise and fall below freezing, as water expands and cracks the rocks when it freezes.
