Answer 16-20 please, please do not comment nonsense if not you will be reported. The first accurate and correct answer gets brainliest

16. is b which is gymosperms

17. is d which is pistill

18. is b which is pollination

19. (I'm not sure of the answer of this question.)

20. is d which is cotyleon

Explanation:

16 is b because gymnosperms are a group of seed-producing plants that include conifers,

cycads, ginkgo and gnetophytes.

17 is d because the part of the stamen where pollen is produced is Anther. Pistill is the ovule producing part of a flower.

18 is b because pollination is the transfer of pollen to sigma.

19 (unknown answer)

20 is d because the food-storing structure in the seed is cotyleon.

this protocol describes a detailed procedure for intracellular flow cytometry staining.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
