Answer:
<em>D) lining up of chromosomes in the cell</em>
Explanation:
Prophase can be described as the first stage of cell division. During this phase, The chromatin material condenses and becomes compact so that the chromosomes become visible. The nuclear envelope disintegrates and the nucleolus disappears. Hence, the choices mentioned in option A, B and C occur by the end of prophase.
Metaphase is the third phase of cell division. During this phase, the chromosomes line themselves in the centre of the cell. Hence, the lining of the chromosome does not occur by the end of prophase. This occurs during the third stage.
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.
Combinations result in the street because two mosquitoes can have bigger or smaller smaller bodies there but he has a small body
