(See figure below, where meiosis I begins with a diploid (2n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Answer:
How Giant Tube Worms Survive at Hydro thermal Vents. In a process called chemo-synthesis, symbiotic bacteria inside the tube worm use hydrogen sulfide spewed from the vents as an energy source for themselves and for the worms.
Explanation:
Answer:
17m/s
Explanation:
Given parameters:
Speed of the bird = 12.5m/s
Speed of the wind = 4.5m/s
Unknown:
Speed of the bird when it flies with the wind = ?
Solution:
The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.
Speed of the bird with wind = 12.5m/s + 4.5m/s = 17m/s
