Answer:
The correct answer would be option D.
Explanation:
Pollen of a plant is a gamete, that contains half of the alleles are required to produce the plant. Pollen fuse with stigma and complete the required alleles or genetic information.
Possible combinations in pollen would be one allele from each trait in every form either dominant or recessive. So ST, St, sT, st. would be the correct possible genetic combination present in a single grain.
Thus, the correct answer is option D.
CO2 can enter through many ways such as
1) Coal emissions from factories
2) The decomposition of living organisms
3) The breathing out of animals
4) Waste and animal waste

<span>Autosomes are
non-sex chromosomes, meaning they are non-sex determining chromosomes inside
cells. Humans naturally have 46 chromosomes in each body cells; 44 of these are
actually autosomes that a person inherits from his/her parents. All persons get
22 autosomes from the mother and the other 22 autosomes will be coming from the
father. These autosomes always come in pairs and since everyone has 44 of these
autosomes in their cells, it should be noted that there are only 22 types that
are obviously numbered from 1 to 22. </span>
Answer:
D) can allow the production of different proteins from a single gene.
Explanation:
Alternative splicing:
Alternate splicing is also known as alternative RNA splicing, or differential splicing. Alternate splicing is a regulated process during gene expression in which multiple proteins are produced from single gene.
Actually eukaryotic genes have both Intron and exon sequences. Exons are the sequences present inside mRNA which convert into amino acids and produces peptides while introns are the sequences which are spliced (cut) from pre mRNA.
Some time introns for some proteins becomes exons for other proteins in this ways one gene can produce multiple proteins.
