Can someone please help me please it's science Some species of frogs live in freshwater ponds, eat bugs, and are prey to heron. These frogs survive loss of water by estivation (an inactive state of deep sleep during the summer). During a period of prolonged drought, which of the following changes to the population of frogs would be expected? The drought would lead to frogs that –

A.) eat more bugs.
B.) require less sunlight.
C.) estivate longer.
D.) can hide from heron.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
