Answer:
Producers, consumers and decomposers
Explanation:
Producers can make their own food by capturing the sun's energy, but consumers and decomposers can't. Consumers need to eat other organisms to obtain energy. Decomposers are like the recyclers of nature. They obtain energy for their own needs while returning simple molecules to the environment.
Answer:
Molarity = 0.202 M
7.36 g/L HCl
Explanation:
KOH + HCl ----> KCl + H2O
1 mol 1 mol
0.560mol/L *0.045L x mol/L*0.125L
0.560mol/L *0.045L = x mol/L*0.125L
x = 0.560mol/L *0.045L /0.125L= 0.2016 mol/L≈ 0.202 mol/L=0.202M HCl
M(HCl) = 1.0+35.5 = 36.5 g/mol
0.2016 mol/L*36.5 g/mol ≈ 7.36 g/L HCl
Centrifugation is usually use to separate different components of blood.
