Corn plants and milkweed plants grow in the same area. over several years, the milkweed plants have taken over the field and the corn plants no longer have space to grow. this best demonstrates which type of an interaction between the plants? cooperation parasitism commensalism competition

competition

Explanation: Cooperation describes an interaction in which organisms work together so that all organisms in the group are benefited.

Parasitism describes an interaction in  which one species i.e parasite is benefited at the expense of host.

Commensalism describes an interaction in which one species benefits and the other neither benefits nor harmed.

Competition describes an interaction in which two organisms that interact must use the same limited resources.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
