I guess the answer is most likely b) they are rare.
solar eclipses can occur fairly often, sometimes 2-4 times a year
Answer:Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. So enzymes speed up reactions by lowering activation energy
Answer:
Dichloroindophenol chemical act as electron acceptor in photosynthesis
Explanation:
DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis
It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant that is produced at the time of photosynthesis with in the chloroplasts.
50% because both are the same Genotyle dominant wise and recessive wise so it will have a fifty fifty chance of having wrinkled seeds
