A book that weighs 0.35 kilograms is kept on a shelf that’s 2.0 meters above the ground. A picture frame that weighs 0.5 kilogra

ms will have the same gravitational potential energy as the book when it’s raised to a height of meters.
(Use PE = m × g × h, where g = 9.8 N/kg. )

E p = m · g  · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J 
( same gravitational  potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9  h
h = 6.86 : 4.9
h = 1.4 m
Answer:<span> ... to a height of 1.4 m.</span>

3. What is crossing over? When does it occur during meiosis? Why did you have difficulty modeling this element of meiosis using
FrozenT [24]
Crossing over happens in Meiosis 1 only. In Prophase 1 a cells chromatin (chromatin = chromosomes that have not condensed yet) condense and pair up forming homologous chromosomes (paired = XX (2 chromosomes together)). When this happens segments/ alleles of the chromosomes pairing up swap over. This creates genetic diversity as each chromosome is different, it has parts from its pair. This leaves every chromosome unique and individual.

I hope this helps, sorry some of the vocab is rather technical. By the way I would suggest watching the 'Crash Course: Meiosis' on YouTube, this really helped me when I was learning this topic. :D
