<h2>Respiration is a <u>
redox</u> reaction where sugar is oxidized to produce energy.</h2>
Explanation:
Respiration is a biochemical process that involves a series of reactions most of which are redox reactions to produce energy by oxidizing sugars.
It involves the breakdown of glucose (glycolysis) in the cellular mitochondria to produce ATP which is the fundamental unit of energy in the human body
The data collected for the purpose of scientific investigations from the ocean should be precise and accurate. The most precise data will be yielded by the temperature readings with a range of 2 degree Celsius. The chances of error in this data will be minimum as compared to the other data whose range is higher. Hence, the set of data with the temperature will yield precise results.
Epigenetic is the study in the field of genetics of cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and of and affects how cells read genes instead of being caused by changes in the DNA sequence. Therefore, hence epigenetic research seeks to describe dynamic alterations in the transcriptional potential of a cell.

<span>The chromosomes are lined up on the cell's equator during the Metaphase stage of mitosis. Almost immediately upon the cells lining up, the Anaphase stage begins, anaphase can be described as a migration of the two chromatids of each chromosome to the opposite spindle poles as they are pulled apart by the mitotic apparatus.</span>
Answer and Explanation:
All cells including the gametes contain chromosomes. Each gamete cell after cell division contains 23 chromosomes. After fertilization, the diploid number of chromosomes which is 46 is restored in the zygote.
Meiosis, a type of cell division, has two phases which eventually lead to the formation of four daughter cells with <u>equal number of chromosomes</u>. Gametes are haploid in nature and thus meiosis I involves separation of homologous chromosomes hence the reduction in the chromosome number. Meiosis II involves separation of sister chromatids in the daughter cells resulting in four daughter cells with 23 chromosomes.
Meiosis ensures that chromosoe number does not double with each successive generation as the resulting daughter cells are gametes, two of which must fuse to form a zygote.
