OLga [1]

Answer:

1/3 of black F2 progeny will be homozygous.

Explanation:

Here, BB = black coat color = true breeding dominant black strain

bb = white coat color =  true breeding recessive white strain

When true breeding black and white guinea pigs are mated to give F1 progeny:

BB X bb = Bb ( all black guinea pigs )

When two of the F1 guinea pigs are mated to give F2 progeny:

Bb X Bb = BB, Bb, Bb, bb

F2 progeny has 3/4 progeny as black (BB and Bb) . Out of them 1/3 are homozygous and 2/3 are heterozygous.

Hence, 1/3 of black F2 progeny will be homozygous.

rjkz [21]

Answer:

The energy from the sun moved in the form of Light radiation, which the Sunflower then used in a process called photosynthesis. They use this to make sugar and that's what grows the seeds. This is then eaten by the cardinal, who uses it as chemical energy to fuel itself. The flower is growing from the energy that the sun gave off, and the cardinal recieves energy from the seeds.
