Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
Answer:
The process by which a cell responds to substances outside the cell through signaling molecules found on the surface of and inside the cell. ... Signal transduction is important for cells to grow and work normally. Cells that have abnormal signaling molecules may become cancer cells. Also called cell signaling.
Egg activation, whether initiated by or independent of fertilization, induces a rise in intracellular calcium. This calcium increase often manifests as a signaling wave that traverses the egg and releases it from meiotic arrest and metabolic dormancy.
Answer:
Rho protein.
Explanation:
Transcription may be defined as the process of formation of RNA molecule from the DNA template. Three important process of transcription are initiation, elongation and termination.
The termination may occur through rho dependent and rho independent mechanism. In rho independent termination, the rho proteins are not required and not necessary for the termination. The uracil stretch is important for rho independent termination.
Thus, the correct answer is option (b).
