Answer:
a) 1:B; 2:C; 3:A; 4:B; 5:C
Explanation:
Primary fuel source for tissues can be defind as the source of energy required for proper functioning of different tissues.
Brain consider glucose, a form of sugar to fuel cellular activities. Food provide glucose energy and through blood brain cell recieves the glucose.
Primary fuel source in resting skeletal muscle are glucose, fatty acids, amino acids that depends on the muscular activity and further participate in the citric acid cycle for oxidation to CO2.
Primary fuel of heart is fatty acids which carry important beta-oxidation equipment and serve as fuel for heart functions.
Glucose is the primary source of energy for adipose tissue which on breakdown contribute to ATP synthesis.
Liver utilises fatty acids, glucose and amino acids as primary fuel source. When glucose is present in high quanity, it converted into fatty acids.
Hence, the correct option is a) 1:B; 2:C; 3:A; 4:B; 5:C
In cellular respiration, energy is converted from glucose, which can be done with and without oxygen
Approximately twenty-five elements occur naturally on Earth.
No, not really because if nothing is near them they cant sense any type of danger. But if something is close they may be afraid but don't sense danger. It basically a spiderman myth.

Answer:
The difference in lighting in this study is an independent variable.
Explanation:
In a scientific study or experiment, the variable being tested or measured or affected by the experiment is called the dependent variable. The independent variable is the variable that is not dependent on any other variables or factors. It is changed or controlled during an experiment in order to cause a change in the dependent variable.
Here, the study is conducted on rats to observe the impact of ginkgo biloba on rat's memory when a measured dose of the same is given through their diet. Ginkgo biloba helps to retain short-term spatial memory in rats. Rats are comfortable in the light and get used to any lighting situations. But they avoid light due to their nature and are generally nocturnal. They cannot see properly in the dark, but can easily navigate through the darkness with the help of their extremely sensible whiskers. The difference in lighting during the experiment acts as an independent variable that is manipulated to induce a change in the dependent variable, to check the ability of ginkgo biloba-enhanced rats and normal diet rats that run through a complicated maze.
