The answer is the third option.

Each offspring will receive one chromosome from each parent. PP can only offer P, and pp can only offer p. Since P is the dominant chromosome, all of the offspring will be 100 percent purple.

The answer is <span>100 percent purple
</span>
Let P be dominant allele for purple flowers and p recessive allele for white flowers. So purebred purple flower has two P alleles and its genotype is PP and purebread white flower has two p alleles and its genotype is pp. Since P is dominant over p, when found together like in heterozygous plants (Pp), the flowers will express dominant allele and will be purple.
So, a cross between <span>purebred purple flowering plants (PP) with purebred white flowering plants (pp) will have 100% of the offspring with genotype Pp and purple flower color.

Parents:               PP      x       pp
Offspring:        Pp     Pp      Pp    Pp

Which organism receives the least amount of energy from the producer?
shepuryov [24]
The owl would have the least amount of energy from the producer. The higher the organism is on the food pyramid, the less energy it will receive from the producer. For example, if grass is a producer, it has the most energy. Then, if a bunny eats the grass, it takes a part of the grass’s energy but does not take all of the energy. Then, a wolf eats the bunny. The wolf gets a part of the bunny’s energy but not all. The wolf has received the least amount of energy from the grass.
