C is correct. the rest is either about food webs or about both food webs and food chains.
Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.
Answer:
2. Stimulating antibody production.
Explanation:
Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
