Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.
Answer:
the Frequency remains constant
Answer: "closed" .

Answer:
Limits to variation The most obvious limit to natural selection is that suitable variation may not be available. This may be because certain phenotypes cannot be built, being ruled out either by physical law or by the properties of biological materials.
I hope it's helpful!
1- When sunlight hits the earth at an angle, like near the north or south poles, it causes the radiation to be spread out over a larger area, than when the sun hits at a 90 degree angle, like at the equator. Therefore, it is hotter in the areas where the solar radiation is more heavily concentrated.
2- Seasons are when the earth's rotational axis tilts towards or away from the sun. It is tilted at an angle of 23.5 degrees, in relationship to the sun. The part of the earth tilted TOWARDS the sun is the area currently in summer. The area tilted AWAY from the sun is the area in winter.
3-This is basically what I already said. The area that is currently summer, is the part of earth tilted towards the sun. The area where it's winter is the part tilted away. And then obviously, spring and fall, are on the sides that are perpendicular to the sun. Hope that helps! If so, please mark Brainliest!
