Answer:
The genotype of the original parents is pp PP
Explanation:
Let “P” represents the purple color allele of the flower of pea plant
and “p” represents the white color allele of the flower of pea plant
Genotype of homozygous purple flowered pea plant is represented by "PP"
Genotype of homozygous white flowered pea plant is represented by "pp"
a) First generation cross between a homozygous purple flowered pea plant and a homozygous white flowered pea plant
P P
p Pp Pp
p Pp Pp
All the offspring are heterozygous purple flowered pea plants
b) In second generation cross is taking place between two heterozygous purple flowered pea plants with genotype "Pp"
P p
P PP Pp
p Pp pp
Out of four offspring , one is white while rest three are purple flowered pea plant.
Hence, the genotype of the original parents is pp PP
Answer:
One of the factors that affects the rate of weathering is exposure to the atmosphere. Rocks that are fully exposed to the atmosphere and environmental elements, such as wind, water and temperature fluctuations, will weather more rapidly than those covered by ground.
Explanation:
Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.
Cancer cells ignore signs
Answer:
B, C and D
Explanation:
Mitochondria and chloroplasts are not found in prokaryotes, since they prokaryotes do not contain any membrane-bound organelles. Chloroplasts are not found in animal cells either, so A is incorrect.
