Answer:
From the outside human arms, bird wings, and bats wings look very different. Humans are covered in skin, birds are covered in feathers, and bats are covered in hair. But on the inside there are many similarities among human, bird, and bat forearms. Did you know that humans, birds, and bats have the exact same types of bones in their forearm? These organisms share the same forearm bones because they all evolved from a common ancestor.
Human, bird, and bat forearm bones include the humerus, ulna, radius, carpals, metacarpals, and phalanges.

Answer:
An object's acceleration depends on its mass and on the net force acting on it.
Explanation:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Answer: Rainfall and temperature can affect the rate in which rocks weather. High temperatures = more rainfall increasing the rate of chemical weathering. Rocks in tropical regions exposed to a lot of rainfall and hot temperatures weather faster than similar rocks in cold, dry climates.
Explanation:
Answer: A (
,309.8°)
B (2
, 315°)
C (
, 26.56°)
Explanation: To transform rectangular coordinates into polar coordinates use:
and 
For point A:
°
Point A is in the II quadrant, so we substract the angle for 360° since it is in degrees:
309.8°
Polar coordinates for point A is (, 309.8°)
For point B:
°
Point B is in IV quadrant, so:
315°
Polar coordinates for point B is (
, 315°)
For point C:
26.56°
Polar coordinates for point C is (, 26.56°)
Answer:
C is the right answer.
