It can support the carrying capacity
The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.
On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.
The given cross represent the cross between purple (PP) and white (pp) pure breeds.
Answer:
a. diploid
Explanation:
After the fertilization process between haploid egg cell and haploid sperm cell, diploid zygote is formed. Zygote has two sets of chromosomes (one from each gamete) which means it is diploid. Sporophyte stage of life cycle will develop from diploid zygote. During the life cycle of a plant (or algae) sporophyte phase alternates with a gametophyte phase which is haploid. In both, seed plants and flowering plants sporophyte phase (roots, stem, leves, cones/flowers) is more prominent than gametophyte phase (pollen, embryo sac).
Sporophyte phase produces spores via meiosis that develop into gametophte.
Answer:
Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.
