Answer:
question 1:
- both the number of species and population density decreases as altitude above sea level increases
question 2:
increase in birth rate => greater number of young organisms
Explanation:
As altitude above sea level increases, O2 density decreases, the amount of UV rays increases and the difference between daytime and nighttime temperature increases
What are the "following" I need to know the possible answers.
Answer:
A: Results In Hypertrophy
Explanation:
Testosterone is responsible for increased muscle mass. Leaner body mass helps control weight and increases energy. For men with low testosterone, studies show that treatment can decrease fat mass and increase muscle size and strength. Some men reported a change in lean body mass but no increase in strength.
Answer:
The correct answer is 4,960,000
Explanation:
If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.
So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.
Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).
Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
Answer:
Most familiar is biparental reproduction (sometimes called dioecious reproduction). ... Dioecious reproduction leaves the greatest genetic variability among offspring (an advantage under changing conditions or in competition or when faced with disease), but the organisms must find mates.
