DNA replication occurs prior to meiosis and _________.
Evgesh-ka [11]
A. Mitosis is the correct answer.

DNA replication occurs in the two major types of cell division: mitosis and meiosis.

Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.

Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).

Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.

Explain the law's of segregation and independent assortment.
VikaD [51]

I hope this helps.

Explanation: The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.

Answer: A low pCO2 indicates respiratory alkalosis which may be primary or secondary to a primary metabolic acidosis. Bicarbonate is calculated from measured [H+] and pCO2 values. A high standard [HCO3- ] indicates either primary metabolic alkalosis or a compensatory response to a primary respiratory acidosis.

Explanation: an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis. The higher the minute ventilation, the more exchange and loss of PCO2 will occur inversely.
