After Synthesis, what ploidy value describes a cell about to undergo a meiotic division in your body?
scZoUnD [109]

Answer:

2n=46(duplicated)

Explanation:

Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.

After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.

Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).

Calculate the average ml of oxygen molecules in 100 ml blood in the athletes at low altitude and then in athletes in high altitu
Neko [114]

Answer:

27.8 mL of oxygen in 100 ml of blood

Explanation:

It is proven that a healthy human being has in general 20 grams of hemoglobin in  100 milliliters of blood.  

It is given that -

Amount of oxygen found in 1 grams of hemoglobin is equal to 1.39 milliliters of oxygen.

Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.

= 20 * 1.39 \\= 27.8 mL
