Crust:crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle,Temperature: Typically in the range from about 500 °C (900 °F) to 1,000 °C (1,800 °F)

Mantle: The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer,Temperature: From
1000° Celsius (1832° Fahrenheit)

Outer Core: Is mostly composed of liquid iron and nickel,Temperature: between 4,500° and 5,500° Celsius

Inner Core: The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles,Temperature: is about 5,200° Celsius

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.
