Answer: A
Explanation: Autotroph is another word for a producer which would mean the protozoan would make its own food and wouldn’t need to feed off the WBC and bacteria. I don’t believe it would a mixotroph due to it not expressing the protozoan has any autotroph-like characteristics. Parasite are usually organisms that thrive and survive on their “host” but also harm them in the process this harm would be the cause of the STD and the loss of needed WBCs
Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria. (Learn more about this process in the article The role of clover.)
Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
Industrially: People have learned how to convert nitrogen gas to ammonia (NH3-) and nitrogen-rich fertilisers to supplement the amount of nitrogen fixed naturally.
Answer:
d
Explanation:
it is a compound chemical made up of 24 atoms
You can tell the difference by the amount of hydrogen in the chemical equation. You can tell by the second one that there is H2, which means there are 2 hydrogens in NADPH2 while NADPH only has 1 hydrogen
