While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape.("Is the Earth round?") If the Earth were flat, then many of the things we know and love today would be gone. The tides, the moon, the atmosphere, etc.
The Earth is round ,even though there are many contradictions. The Earth spins on an axis, which is why there are different time zones all around the world. If the world was flat, then an Earth's core wouldn't exist and also the laws of gravity would not make since due to the Earth being considered flat. People would never know if they met the end of the Earth, or if they walked off the face of the Earth. Also note that if the Earth was flat then our Solar System would have to be flat since it involves the planets to revolve around the Sun.
50% Not sure how you would draw the punnett square, however heterozygous means different so it would be Ab and homozygous dominant means the same but one is upper case and one is lower case Aa.
