What must happen for most areas on Earth to experience all four seasons?

The Sun must reach its highest point in the sky.
The Northern Hemisphere must experience winter.
The axis must be tilted at a certain angle that remains unchanged.
The north end of Earth’s axis must always point away from the Sun.

The Earth spins counterclockwise on its axis at an angle of 23.4 degrees. This spinning of the Earth causes day and night because only half the world faces the sun. Moreover, as the Earth spins on its axis, it orbits the sun, taking 365 days to complete a whole orbit. Because of the tilt of the Earth's axis, different areas receive different amounts of sunlight during the Earth's orbit, creating the four seasons.

Explanation:

The timing of the seasons is opposite for each hemisphere. This is because when the north pole is tilted toward the sun, the northern hemisphere faces the sun at a greater angle than the southern hemisphere. Therefore the northern hemisphere gets warmer. This represents the summer months for the northern hemisphere and winter for the southern hemisphere. As the Earth continues its orbit, the south pole eventually is tilted toward the sun, reversing the seasons in each hemisphere.

C. The axis must be tilted at a certain angle that remains unchanged.

Explanation:

I took the quiz:)

ysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. lysosomal enzymes are synthesized in the endoplasmic reticulum (er), are transported to the golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.

explanation:

the sphincter muscles at the end of the digestive tract is the anus.
