Which of the following is the best example of a proper hypothesis? i think there is no effect on hearing if you listen to loud music for only three hours a day. grapes taste better than apples because grapes are sweeter. if different types of leaves are exposed to low temperatures, then they will change colors. water will flow faster through tightly packed soil than through loosely packed soil.

Hello!

I believe the answer is D) Water will flow faster through tightly packed soil than through loosely packed soil.

I hope it helps!

Option C is correct - If different types of leaves are exposed to low temperatures, then they will change colors.

Hypothesis can be described as a conditional description of the predicted connection between two or more variables under examination.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
