Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells

Answer:
The correct answer is option d.
Explanation:
Based on the given question, the genotype of the male parent is aa, the genotype of the female parent is Aa, and the genotype of the offspring is AAa, showing trisomy characteristics. In the given case, the existence of two A chromosomes shows that the chromosomes non-disjunction at the time of gametogenesis have taken place in the female as she is the only one possessing A allele. Hence, it can be concluded that the disjunction is maternal in characteristic.
The duplication of chromosomes takes place at the time of the S-phase of meiosis. Thus, after going through S-phase, the karyotype of the cell will be AAaa (maternal gametogenesis), this set of the chromosome is termed as homologous pair, and the pair of AA or aa is termed as sister chromatids.
The meiotic disjunction takes place in two phases. First, in meiosis I disjunction, in this separation of homologous chromosomes takes place, that is, the maternal cell AAaa get differentiated into aa and AA daughter cells. Secondly, in meiosis II disjunction, the separation of sister chromatids takes place into two independent chromosomes, that is, the formation of two cells each comprising chromosome A from the AA cell and the formation of two cells each with chromosome a from the aa cell.
Thus, the phenomenon of non-disjunction would have taken place at the time of meiosis II in the case of a female gamete to exhibit two A chromosomes. Hence, the correct answer is option d.
Answer: flowers,other minerals
Answer:
A)Ocean floor evidence of sea floor spreading.
Explanation:
evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,
What is the tectonic theory?
The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.
What is a tectonic plate?
They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!
