A independent variable is a variable which the experimenter can control and by changing the independent variable the experimenter observes or records the value of dependent variable.
so i see if you are asking independent than the answer is A.
if you are asking dependent variable than the answer may be B because manipulated by changes to the independent variable would be the best answer.
Answer: Metabolic rate is the total amount of energy an animal uses in a unit of time
Explanation:
Hi, metabolic rate is the total amount of energy an animal uses in a unit of time.
It refers to how quickly fuels are consumed to keep the organism’s cells functioning.
Its unit of measure can be Joules, calories or kilocalories per unit of time.
Metabolic rate is proportional to the activity level. The More active the animals is , the higher the metabolic rate is.

a combined transmitter and receiver called a transducer sends a sound pulse straight down into the water and the pulse moves through the water and bouces off the ocean bottom so that the transducer is able to pickup the reflected sound
Answer:
The observation is an evidence of static electricity.
Explanation:
Static electricity refers to the stationary electric charge that is produced by friction. In other words, this kind of electricity is created when objects (2 objects for example) that are not good conductors of electricity are rubbed together.
During the rubbing process, electrons from the objects come in contact leading to the creation of a stationary electric charge. A good example of static electricity is when you are combing your hair and you see a spark in the mirror.
Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
