Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
Answer:
I'm not sure but maybe for the first it's less than 3% and for the second it's equal to 3%?
Explanation:
Answer:
Q.1: I can't help you with this, sorry :(
Q.2: Seaweed is the producer because it takes energy from the water and sun in thermal reactions.
Q.3: Phytoplankton is the second-order consumer because they eat first-order consumers.
Q.4: Whelks and crabs because they eat limpets, which eat producers, and they also eat seaweed.
Q.5: Gulls are carnivores because they eat the crabs, and so are crabs because they eat mullets
Q.6: Limpets and lobster would become less populated, but not yet endangered. Gulls would starve and probably disappear from this ecosystem.
Q.7: Whelks' numbers would decrease because of the number of lobsters consuming them, but then lobsters would starve because of the decline in their food. Then this would repeat, shaking the whole ecosystem.
One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
Answer : A : They live in extreme environmental conditions.
