1) The angle that Earth is tilted on its axis changes.
Explanation:
Surface of earth received more sunlight due to the tilting of the earth toward sun. Tilting is the property of the earth in which earth rotate its one end toward the sun. This tilting of earth is responsible for the formation of seasons on the earth. Earth tilt about 23.5 degrees toward sun. If there is no tilting occurs, no seasons will be formed.
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
