The only true answer here is B. if you have a periodic table, you can see that Magnesium atomic number is 12 while Aluminium's is 13. this means Al has 1 more proton and weights more than magnesium since proton and neutrons contribute to the weights of the atoms.
Answer:
1.yes
2.no
3.yes
Explanation:
1.Yes. The sugar in milk comes from naturally occurring lactose, not added sugar.There are about 12 grams of natural sugar (lactose) in each 8-ounce glass, which is about the same amount of natural sugar you would find in one small banana. Flavored milk, like chocolate, does contain added sugar for flavor.
2.In lactose-free dairy, the lactose is predigested into glucose and galactose. Consequently, the lactose content may be very low (<0.1 g/L), but the glucose and galactose content of lactose-free milk will be approx. 25 g/L.There is no added sugar in plain lactose-free or regular milk.
3.milk is composed of two molecules of simple sugars—glucose and galactose—that are chemically bonded together. The enzyme lactase breaks down lactose into glucose and galactose, which are easily digested by humans.
The EPA is an independent agency formed for environmental protection. Hence the statement The Clean Air Act would be a reason for the Environmental Protection Agency (EPA) to regulate car emissions is true.
Car emissions are very harmful for all the living organisms in an environment.
Answer: parallax is the best answer
B
Area B of the graph shows the activation energy required if an enzyme was not present
Explanation:
Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.
Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.
