In the 2015 VCAA exam Q9b asks
"What name is given to the study of the similarities and differences between the bones and skeletal structures of animals, including fossils of extinct species?"
I put structural morphology but the answer was comparative anatomy. I'm not really understanding the difference between them, could someone explain this to me? Why would it not be structural morphology because I have it in my notes that it is the study of the structure of organisms. Also comparative anatomy is not a term used in the study design.
I also have another question for Q7c in the 2015 VCAA exam that asks
"In the rat pituitary gland, GC stimulates the production of the growth hormone protein. However, in the rat liver, GC stimulates the production of the enzyme tryptophan oxygenase. Given that the genetic sequence is identical in all somatic rat cells, explain how the production of distinct proteins in different cell types could occur."
I had no clue what to write and the answers say that factors expressed by regulator genes could lead to production of the different proteins. How can factors do that when the genetic sequence is identical in all rat cells? Do the factors cause different splicing in two different cells which results in two different proteins? I think I'm way off but I really can't understand this question and I don't think I'm alone cus 94% ppl got it wrong as well that year.
Thanks.
