Answer:
No, the light-dependent reactions doesn´t depend on the Calvin Cycle
Explanation:
While the Calvin cycle produces ADP and NADP+, both of which are photophosphorylated by the light-dependent reactions, there is another carbon cycle, called PHOTORESPIRATION, in which the enzyme RuBisCO (RuBP oxygenase-carboxylase), OXYGENATES RuBP (ribulose-1,5-bisphosphate), instead of the CARBOXYLATION OF RuBP (the normal Calvin Cycle), releasing 3CO2 and spending ATP and NADPH (produced by the light-dependent reactions), thus, providing the ADP and NADP+ photophosphorylated by the light-dependent reactions.
PHOTORESPIRATION results in a NET LOSS of fixated carbon, and is activated by certain conditions like HIGH TEMPERATURE and LOWER CO2 AVAILABILITY (due to CLOSED STOMATA as a response to droughts). However, the main functions of this system are not clear. It may be involved in nitrate assimilation, free radicals regulation, plant growth, homeostasis of plant cells, among others.
Near volcanic areas where there is a lot of lava flow, and cracks in ground.
Answer:
(4) is bred and the trait is capable of being inherited
Explanation:
<u>Mutation generally refers to a sudden change to the DNA sequence in the genome of an organism.</u>
Since, DNA is the molecules responsible for heredity and the inheritance of traits by offspring from their parents, a mutation should be inheritable.
<em>Hence, if a sudden appearance of hairlessness in one of the puppies is observed by a dog breeder, he/she can effectively conclude that the situation is caused by a mutation if the affected dog is bred with another dog and the hairlessness is observed in any of the resulting progeny.</em>
Option 4 is the correct option.
