Answer:
haploid
Explanation:
The ploidy level of a single mature ascospore is haploid with half the number of chromosome present in a single diploid cell.
Ascospore are produced by meiotic division of the single diploid cell and meiosis leads to the production of haploid cells because it involves the reduction of chromosome number.
<em>Hence, if the diploid cell with 14 chromosomes undergo meiosis, it will give rise to haploid cells with half the number of chromosome (7) of the diploid cell.</em>
Answer:
1. Ozone
Explanation:
Ozone is a substance with the chemical formula, O3, found in the stratospheric part of the atmosphere. It functions to prevent the harmful ultraviolet (UV) radiation from the sun from reaching the Earth. However, due to anthropogenic activities i.e. human activities that releases greenhouse gases e.g. CO2, CFC etc. the protective function of the ozone layer is wavering.
Hence, based on this question, people are concerned over the fact that this OZONE layer is depleting, hence, risking the exposure to the harmful radiation from the sun.
