One independentvariables can be tested in a controlled experiment. The correct option is A.
A person, place, thing, or phenomenon that you are attempting to quantify in any way is simply referred to as a variable in research.
The best approach to distinguish between a dependent and independent variable is to look at what the words themselves reveal about the variable you're using.
Only one variable at a time should be tested in an experiment. This guarantees that the experimental result is definitely caused by a single, recognisable component.
A controlled experiment in a scientific study is a test that the researcher actively modifies such that only onevariable is examined at a time.
Thus, the correct option is A.

B) accessing food
C) obtaining oxygen
D) avoiding predators
Answer:
The answer is C
Explanation:
Because in order for it to breath well it needs to move its gills
White tip reef sharks pump water across their gills to obtain oxygen.
White tip reef sharks spend most of the day lying on the ocean floor. They pump water across their gills while remaining still, as the movement of water across their gills is necessary for obtaining oxygen. Gills in fish, including sharks, absorb oxygen from the water as it passes over them. Sharks have well-developed sense organs that aid them in locating prey, including a keen sense of smell and the ability to detect electromagnetic fields.
Electroreceptors called ampullae of Lorenzini allow sharks to detect the electromagnetic fields that are produced by all living things, including their prey. The lateral line is used to detect movement and vibration in the surrounding water, and is often considered to be functionally similar to the sense of 'hearing' in terrestrial vertebrates.

recycled products on plant growth. Miguel’s lab
group compared the effect of different aged grass
compost on bean plants. Because decomposition is
necessary for release of nutrients, the group
hypothesized that older grass compost would produce
taller bean plants. Four flats containing the same
species of bean plants (25 plants/flat) were grown for
5 days. The plants were then fertilized with compost
as follows: (a) Flat A: 450 grams of two-month-old
compost; (b) Flat B: 450 grams of four-month-old
compost; (c) Flat C: 450 grams of six-month-old
compost; (d) Flat D: 0 grams of compost. The flats
of beans were planted in the same type of soil. The
plants received the same amount of sunlight and
water each day. At the end of 30 days, the group
recorded the height of the plants in centimeters. What is the flaw in this experiment?
