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.

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>

If an organism has an ‘n’ of 32, how many chromosomes are in its somatic cells? How many chromosomes are in its gametes?
Alex

<em />n represents the haploid number of an organism. We know that gametes are haploid, therefore there will 32 chromosomes in each gamete. A somatic cell on the other hand is what we know as a body cell, which is a product of mitosis. Mitosis produces diploid cells which is represented by 2n. In order to find this value, simply multiply the n value by 2 and you should get 64 chromosomes in each somatic cell.

If interbreeding within the hybrid zone of the mountain pass decreased over time, what would you expect to happen to the Western
tamaranim1 [39]

Answer:

The two population will become separate species due to allopatric speciation

Explanation:

Allopatric speciation is also known as geographic speciation. In this speciation two populations of the same species isolated geographically from each other which prevents gene flow between them and the two populations evolve separately and over time, it leads to the creation of a separate species.

So here as interbreeding within the hybrid zone of the mountain pass decreased over time so it will lead to speciation in these populations and they will evolve into two separate populations due to lack of gene flow as a result of geographical isolation.

Why is nonpoint source pollution more difficult to control than point source pollution?.
Alex787 [66]

Answer:

true

Explanation:

<em><u>Some water pollution is caused from “point sources” that is discrete locations, from which pollutants are discharged, e.g., a pipe, ditch, ship, or factory smokestack. Point sources originate in large and easy to trace facilities, hence are easier to control. In contrast, pollution from “nonpoint” sources is cumulative, arising from multiple inputs over larger areas, such as farms, city streets, and residential neighbourhoods. Hence, such sources are harder to precisely identify, and because of this uncertainty, nonpoint source pollution is harder to control than the point source.</u></em>
