One-celled (single-celled)
organisms, however, tend to be different from those with many cells.Larger celled organisms <span>such
as plants and animals, have a higher degree of specialization where the cells
work together and function to create a living organism.</span>
Answer:
Water soluble hormones bind to a cell surface localized receptor initiating a signaling cascade using intracellular second messengers for example epinephrine.
Hormone binding activates the G-protein and G-protein activates the adenylyl cylase and it catalyzed the conversion of ATP to cAMP which is second messenger in this pathway. cAMP activate the protein kinase and then protein kinase activate certain cytoplasmic protein which alter the activity of cell.
<span>The answer is: A. It ranks organisms by importance in evolutionary history.
The phylogenetic tree represents only the relationships among organisms but does not rank their importance. It uses hypotheses other than facts in presenting the events of speciation based on their ancestors.</span>
Answer:
DNA sequences.
Explanation:
DNA sequences, I believe, are the best evidence of common ancestry since they share more traits with more closely related organisms. The similarities and variances in fossils, anatomy, and embryos are all due to DNA.
