The erythrocyte count increases after a while when an individual goes from a low to a high altitude because the concentration of oxygen is lower at high altitudes.
What are erythrocytes?The erythrocytes are specialized red blood cells required to transport oxygen to all cells in the body.
This oxygen is fundamental for carrying out the process of cellular respiration by means of cells and tissues.
The amount of red blood cells in the bloodstream is dependent on the altitude at which the person lives.

The main food sources of beta-carotene are: yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers. yellow fruit, such as mango, papaya and apricots.
Preformed vitamin A is found in animal products such as meat, fish, poultry, and dairy foods. Precursors to vitamin A, also known as provitamin A, are found in plant-based foods such as fruits and vegetables. The most common type of pro-vitamin A is beta-carotene.
Vitamin B12 is found only in foods of animal origin, therefore, vegans (strict vegetarians who consume no animal products) may need to supplement their diets with this vitamin.

A state agency wants to release endangered hawks but needs to determine the best site for their release. The state would like to know how many rabbits are in each area to determine which area has the largest prey population. Create a plan to determine how many rabbits are in each area to determine which site is the best location. Your plan should include specific information on how many animals will be tagged and how many samples should be taken to get the most accurate results. Use your simulation data to help you develop this plan
We choose that site which have large number of rabbits because rabbits are the food of hawks.
Which location should be selected?That site should be considered the best which has large number of rabbits because rabbits provide food for hawks so increase in population occurs in that location. We know that rabbits are the food of hawks so without suitable amount of food, the population of hawks is unable to increase.
So we can conclude that we choose that site which have large number of rabbits.

Which advantage of reproduction does the graph show? Explain!
The explanation regarding the advantage of reproduction that represents the graph should be described below.
Advantages of reproduction:
Here the graph represents the bacteria population that should be raised as the time passes. At the time of 1st hour, the bacteria population should be 50 per ml.
In the second hour, the population should be doubled. In the third hour it should be 200 per ml and in 3 and half hours, the population should be 300 per ml. So here we can see that the population should be doubled with every hour.
