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>

And what determines if something is living is whether are not it can reproduce without the assistance of a host organism. Some organelles all cells contain whether prokaryotic are eukaryotic are cell membranes Genetic material (DNA and forms of RNA) a cytoplasm and ribosomes. Obviously there are many more organelles but these are some shared by all cells whether prokaryotic, eukaryotic or plant a type of eukaryote.

In the parental generation, inbred black and an albino mice parents mate. The resulting F1 mice are black and heterozygous at 2
Semenov [28]

Answer:

12:4:3

Explanation:

Let the lack of color pigmentation which is recessive be aa where AA and Aa allow for color (BB, Bb - black, baby - white).

The F1 parents are BbAa x BbAa

This cross will produce 12/16 blacks, 4/16 albinos and 3/16 white.

Science Question 3, Thanks if u help!
noname [10]

Answer:

The correct statement is option C. Mitosis produces cells which are identical to parent cell, while meiosis produces cells that carry half of the genetic material of the parent cell.

Explanation:

Mitosis is a type of cell division in which a single cell is divided into two body parts. This cell division is present in body cells. The cells which are formed are identical to parents while meiosis cells are different from one another. In meiosis, the number of chromosome is half of the parent cell.
