What adaptations of the harpy eagle allow it to be such a successful rainforest predator?
IgorC [24]
The ranking of most eagles in the food chain is at the top. They are called apex predator.

The harpy eagle is one of the largest eagle there is. Common to most eagles are its sharpness of their vision. Most eagles use it to sight their predator while circling above the ground at a distance unseen by the prey. However, harpy eagles adapted a way of hunting prey which is called perch-hunting.

Perch-hunting is a way of looking for predator by scanning the trees for prey by flying in short distances from a tree to another tree. The harpy eagle developed this skill since it is hard to sight a prey in a rain forest because of the leaves and trees blocking its vision. Hence, perch-hunting is very apt for the scenario of a rain forest eagle.

Chemistry omg need help plz I need plz. I real badly at it and try to get better but plz help me
Rufina [12.5K]
We all struggle in some subjects, you do badly when you don't try, and sometimes we try and can't get the answer, I'll help with that. :)

The first answer is CO2(g), CO2 is a gas, and all gas have... 4) No definite shape, no definite volume.

A piece of ice, a block of wood, and a ceramic cup are solids. They have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume.

A liquid takes the shape of what holds it, besides a flat surface, which will just evidently, take the shape of a flat surface. A liquid has a definite volume, because the volume of a liquid is constant because forces of attraction keep the particles loosely together.

Gases attempt to fill a container of any shape or size. Therefore, it has no definite shape.
There are forces of attraction among the particles in all matter, therefore, it has no definite volume.

The second question might become easier with the explanation above. A liquid has a definite volume because the forces of attraction are loosely together! Therefore, it has a definite volume, but it will take the shape of it's container.

This means... Yes! 2) It retains its original volume but changes shape.

This one is easy. To convert one gram of a solid at its normal heating point to a liquid at the same temperature, is the 1) Heat of Vaporization.

Heat of Vaporization is the amount of heat energy required to convert one gram of a substance from a liquid to a gas.

The third question, the molecules for H20, in a solid phase are always in an geometric and arranged pattern.

Most solids are arranged in geometric and arranged patterns, and since H20 is not in its indefinitely shaped liquid phase, it has a definite shape and thus, retains a repeating (geometric) pattern.

(Note- Some solids like wax or rubber do not have an arranged or geometric pattern.)

The “average of a kinetic energy” is defined as the vitality of movement of particles of a framework.

Or in simpler terms, “energy motion”.

So when temperature increases, the average kinetic energy of a molecule(s) 1) increases.

Explanation:

Cells are able to re produce themselves without other cells needed. If cells need others to make more then how would that work and plus we wouldn't have the theory of cells existing.
