The correct answer is A. Are bass more active in the daytime than at night?

Explanation:

A testable hypothesis refers to a possible explanation or guess about a phenomenon that can be proven as valid or invalid through experiments or tests. Due to this, a testable hypothesis should emerge from questions that focus on a specific natural phenomenon; moreover, the phenomenon studied should be measurable and objective, due to this, aspects such as opinions, feelings or perspectives are not recommended.

According to this, the question that can be used to form a testable hypothesis is "Are bass more active in the daytime than at night?" because this focuses on a phenomenon that is measurable and objective as you can measure the level of activity and this does not depend on the perspective or opinion of people. Moreover, others such as "When whales jump out of the water, are they happy?" or "Are red tulips prettier than tulips of other colors?" are too subjective, and therefore these are not testable.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
