The potato placed in vinegar produced _________.

Biology
1 answer:
anastassius [24]2 years ago
3 0

Answer:

Most living tissue contains catalase. We can use potatoes to help see catalase work because bubbles of oxygen form when we put potatoes into hydrogen peroxide.

Explanation:

As catalase decomposes hydrogen peroxide into water and oxygen gas, bubbles of oxygen collect on the disk. When the density of the combined paper/enzyme/O2 is less than the solution the disc will rise to the surface.

B cells interacting with helper t cells are stimulated to differentiate when _____.
madam [21]
There are choices for this question namely:

<span>A) B cells produce IgE antibodies
B) B cells release cytokines
C) cytotoxic T cells present the class II MHC molecule-antigen complex on their surface
D) helper T cells release cytokines

The correct answer is "helper T cells release cytokines". Cytokines are released by helper T cells when B cells attach to them via receptors. These T cells "help" these B cells to differentiate by secreting certain cytokines. When B cells differentiate, they are converted to plasma cells and able to secrete antibodies to the antigen presented to the T cells. </span>
