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.
Answer:
Amount of sleep
Explanation:
There are two types of variables in a scientific experiment.
<u><em>Independent variable:</em></u> An independent variable can be described as the variable which is changed or can be controlled during the experiment. The effects of the independent variables on the dependent variable are tested.
In the scenario discussed in the question, amount of sleep will be independent variable as it is not dependent on any other factor.
<u><em> Dependent variable:</em></u> It is the variable which is being tested or measured due to changes in the independent variable.
In the scenario discussed in the question, the exam score will be the dependent variable as it will be dependent on the independent variable i.e amount of sleep.
