Atestable hypothesis could be formed from which question?
are bass more active in the daytime than at night?
when whales jump out of water, are they happy?
are red tulips prettier than tulips of other colors?
why are gerbils more popular as pets than hamsters are?

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.

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
