Explanation:

Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.

Answer:

A) In this wild mustard, there is enough heritable variation to permit these different varieties

Explanation:

The mentioned varieties were created by artificial selection for various traits in the wild mustard Brassica. This wild type plant was native to Europe and Asia and had a wild range of genetic variations to allow the development of different strains.

For example, the selection of strains that formed the overlapping leaves led to the development of cabbage. Repeated breeding allowed this trait to become prominent as it is in the modern cabbages. Likewise, the strains of the wild cabbage that had prominent storage stem gave rise to kohlrabi while the strains with enlarged axillary buds were selected for the development of brussels sprouts.

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the

dedylja [7]

Area circle = π*r²

Area square = l²

The side of the square is equal to the diameter of the circle

Area square = D²

A diameter is always twice the radius

Area square = (2r)² = 2²r² = 4r²

So this is the rate:

Area circle/Area square = (π*r²)/(4r²)

Area circle/Area square = π/4

Volume is always Area*h when cross sectional area is a constant

Volume Prism = Area Square*h

Volume Prism = 4r²*h

Volume Cylinder = Area Circle*h

Volume Cylinder = π*r²*h

So far this is option D)

Let’s calculate the rate:

Volume Cylinder/Volume Prism = π*r²*h/4r²*h

Volume Cylinder/Volume Prism = π/4

Volume Cylinder = π/4* Volume Prism

This is also option D)

Now let’s calculate Volume Cylinder from that formula:

Volume Cylinder = π/4* Volume Prism

Volume Cylinder = π/4 *(4r²*h)

This is also option D)

So option D) is correct

Answer:

Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
