Answer:
Because each subject in an experiment has to have equal conditions to ensure the most accurate results. And water temperature is known to impact plant growth. An experiment using different water temperatures is a terribly inaccurate experiment.
Labeo = gills
Dolphin= pisces
Tadpole = hibernation
snake= internal fertilization
Eagle = aerial mode of life

Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system
Explanation:
The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.
The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air
Answer:
D. decreasing in population.
Explanation:
Triggerfish are the brightly colored fish and sea urchins are the globular animals, echinoderms. Triggerfish eat sea urchins for their survival.
An increase in the use of recreational boats over the area will damage the habitat of the triggerfish and also affect their food supply, it will result in a decreasing population of triggerfish. Due to lack of sea urchins and habitat disturbance, the Triggerfish population will decrease
Hence, the correct answer is "D. decreasing in population."
