Answer:
Explanation:
Since the offsprings all exhibited purple phenotypic characteristics, It shows that in the gene coding for colour in the flower of the pea plant, the allele for purple colour is dominant over the allele for white colour.
It further shows, according to the law segregation, that the gametes produced by the purple and white peas are dominant and recessive respectively. This Indicates that the parent purple-flowered pea is homozygous dominant (PP) while the parent white-flowered pea is homozygous recessive (pp), hence all the offsprings will be heterozygous dominant (Pp).
Answer: d. none of the other answers
Explanation:
Enzymes that turn chemical energy into mechanical work are molecular motors.
There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin filaments and microtubules carry the motor-driven transport on the cytoskeleton.
The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.
Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.
Hence, the correct option is d.
The answer is A because it right
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
