Answer:
Based on the provided data, the six goldfish are placed in aquariums of varying sizes to assess how living space impacts their survival rates. The food type and quantity, sanitary conditions, and water temperature are kept consistent across the board.
Consequently, from this information, one can conclude that:
A. The independent variable is the aquarium size.
B. The number of fish remaining after six months represents the dependent variable.
C. Water temperature, food type and quantity, upkeep, and cleanliness are the controlled variables or constants.
Controlled experiments include both dependent and independent variables. The independent variable is usually the one that is altered and compared against a stable control. Meanwhile, the dependent variable, which is measured in the experiment, relies on the independent variable. The control group in an experiment is kept constant and is used for comparison with the experimental group.

A muscle cramp happens when a muscle contracts involuntarily and suddenly. Various factors can cause this, such as insufficient minerals like calcium or poor blood flow.
By straightening and vigorously massaging an athlete's leg, the muscle relaxes and returns to its normal position.
Answer: starch
Explanation:
Starch, a carbohydrate, is produced by plants and is primarily found in seeds and tubers.
Starch is also used to treat cotton shirts, as it forms glycosidic bonds which contribute to the fabric's quality.
This compound consists of amylose and 70%–90% amylopectin. Amylose, a polysaccharide, comprises D-glucose monomers linked by the α-1,4-glycosidic bond, forming a helical structure with six glucose units per full turn.
Amylopectin, another polysaccharide, features glucose molecules primarily linked through α-1,4-glycosidic bonds, with occasional branching due to α-1,6-glycosidic connections. Each amylopectin molecule can have many thousands of glucose segments, with branches occurring roughly every 25 to 30 units.
