Answer: Cell differentiation can be defined as a process in which the less specified cell is converted into the more specified cell. The cells at the embryonic stages is less specialized and during the process of development it becomes more specialized and this process is regulated by gene expression. The gene expression involves a specific group of genes which is expressed or suppressed, that decides the function of the cell.
A fertilized egg shows a single cell which is non-specialized that will become complex and will turn into a multicellular organism by cell differentiation.
This is the reason the adult rabbit looks so different from the single fertilized egg.
Answer: Glucagon stimulates lipolysis and decrease ghrelin levels.
Explanation:
Glucagon is an hormone that is secreted in the pancrease which convert stored glycogen to glucose that is released in the blood. High blood glucose increase insulin levels. Too much of glucagon can cause diabetes. Glucagon stimulate lipolysis which provide fatty acids to tissues to be use as fuel. Glucagon decrease the ghrelin levels. Glucagon stimulates amylin secretion.
the locomotary organs are cillia, flagella and pseudopodia or is called false feet
