When you have an answer for t you want to compare it in the given table. You need to always look at the p value of 0.05 (just ignore the others, IDK why but for biology you use this). Then you want to calculate the degrees of freedom= (n-1)+(n-1) where n is the number of data that you have. This will also be in the table and then you choose the value which is equal to both of those values. So for example, if your degrees of freedom is 26 and p=0.05 look across here and see where they meet. Then using that value there and your answer you can work out if the null hypothesis should be rejected.
If your t value is much greater then the two areas/habitats (whatever is being tested) are significantly different due to a biological factor and not due to chance In this case you reject the null hypothesis.
Thats all you need to know.
Hey! I'm really panicking.. Can you please go over the specific immune bit with the T lymphocytes and B lymphocytes. I understand phagocytosis.
Hey! I'm really panicking.. Can you please go over the specific immune bit with the T lymphocytes and B lymphocytes. I understand phagocytosis.
So after phagocytosis, the antigen is represented on the plasma membrane of an antigen presenting cell. This is recognised by T lymphocytes. The T lymphocyte with the complementary receptor to the shape of the antigen is selected (clonal selection). This then divides by mitosis (clonal expansion) and the resulting cells can then differentiate into other cells: These include: T-helper which uses interleukins to communicate with other cells and stimulates clonal expansion of B lymphocytes T-killer which kills any infected cells hence destroying the pathogen T memory which provides long term immunity T regulatory which shuts down the immune response after the pathogen is dealt with.
Once the B lymphocytes are active they also divide by mitosis and can differentiate into the following: B memory cells which provide long term immunity Plasma cells which produce antibodies
Some possibilities Describe the 2 theories of enzyme action How proteins are made Cardiac cycle Specific immune system
Or they could be stupid and tell us to write about a practical
Thanks, yeah hopefully we don't get a practical question.. And are the two theories of enzyme action that youre talking about the induced fit and lock and key or something else?

Yeah induced fit and lock and key.. At least one will pop up
