Answer:
Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions.
Explanation:
Sexual reproduction produces genetic variability, as two nucleic unites to produce a new offspring this allows the fungus to adapt to new environments. Sexual reproduction in the fungi consists of three sequential stages plasmogamy, karyogamy, and meiosis.
It involves diploid chromosomes pulled into two daughter cells, each containing an haploid set of chromosome.
Plasmogamy is the fusion of two protoplasts which brings together two compatible haploid nuclei this nuclear types are present in the same cell, but are not yet fused. Karyogamy then leads to the fusion of the haploid nuclei and the formation of a diploid nucleus. The new cell formed by karyogamy is the zygote.
Most interactions between organisms occur in the biosphere because biosphere is the ecological system of Earth. This means that it cannot be affected by things such as solar and cosmic radiation, and it is self-regulating
The biosphere is also termed as the zone of life on earth and the zone of life on. This makes the biosphere<span> very </span><span>important for living organisms</span>
Answer:
Separation of sister chromatids and centromeres.
Explanation:
Once chromosomes align along equatorial plate during metaphase of mitosis, the next step of mitosis is separation of the sister chromatids and the centromeres. The separation of sister chromatids and the centromeres occurs during anaphase of mitosis. During this phase, spindle fibres which are produced from centrioles in the centrosome at two opposite poles of the cell, attach to the centromere region of the chromosomes and drag each sister chromatid of the chromosome apart towards opposite pole of the cell. This is how each opposite pole receives one chromatid from each chromosome. Later during telpophase of mitosis, cytokinesis occurs which produces two daughter cells with equal number of chromatids.
