1. do you think erythropoietin levels in athletes at low altitude are lower, higher, or the same after training at a high altitu

de for 2 months?
2. calculate the average ml of oxygen molecules in 100 ml blood in the athletes at low altitude and then in athletes in high altitude while training at high altitude. use the following information: 1.39 ml of oxygen per gram of hemoglobin.
3. do athletes training at high altitudes have more or less oxygen molecules per ml of blood then athletes training at low altitudes? explain why this difference gives athletes who train at high altitudes an advantage over athletes who train only at low altitudes.

1. Erythropoietin will be higher at low   altitude. Erythropoietin or EPO level will be higher because of the raised blood oxygen training but its lasting period will depend on the training content as here it is only 2 months.

About high erythropoietin:

Among the objectives of altitude training is to improve athletes' sea-level endurance performance by raising blood oxygen carrying capacity. The attainment of improved haematological variables is mostly due to the augmented erythropoietin (EPO) production in hypoxia. The duration of exposure and degree of hypoxia affect the level of the erythropoietin EPO rise and the rate of erythropoiesis acceleration. The haematological response to altitude training may also be influenced by a wide range of additional factors.

2. 100 ml of blood contain 27.8 mL of oxygen. This can be said as it has been shown that a healthy person typically possesses 20 grammes of haemoglobin in every 100 millilitres of blood.

Procedure:

=20∗1.39

=27.8mL

Amount of oxygen found in 11 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.

3. Athletes training at high altitude have more oxygen molecules. They have an advantage as a result of having more red blood

Why so:

Higher elevations have thinner air, which has less oxygen molecules per volume of air. The body therefore makes more red blood cells when athletes workout at these high elevations. For up to 20 days, these additional blood cells remain in the body. Also as a result of having more red blood cells, their blood can carry more oxygen. When they compete at lower elevations, their muscles naturally get a boost from more oxygen.

Zolol [24]

The correct answer is:


A: 3.21% (m/v) NaCl Solution will cause crenation because it is hypertonic solution (more solutes)  

B: 1.65% (m/v) glucose Solution will cause hemolysis because it is hypotonic solution


C: distilled H2O Solution will cause hemolysis because it is hypotonic solution


D: 6.97% (m/v) glucose Solution will cause crenation because it is hypertonic solution (more solutes)


E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl will cause neither crenation or hemolysis because it is isotonic solution.

Meiosis halves the chromosomes number, how is the 2N condition restored? A. mitosis B. it is not restored C. fertilization
cricket20 [7]
The answer is letter C. fertilization.
Meiosis reduces the chromosome number from diploid (2n) to haploid (n).
<span>During fertilization like that of human somatic cells which has 46 number of diploid chromosomes, a haploid sperm cell and a haploid egg cell combine to form a diploid zygote. Each parent contributes 23 number of chromosomes to the offspring which makes the total of 46 chromosomes. Since meiosis halves the chromosome number but the diploid condition is restored during fertilization</span>
