Compare the properties of the parent and daughter cells in mitosis and meiosis and explain the reason for any differences.
katrin [286]
Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>

You are watching sleep researchers monitor the sleep of a normal adult. The participant is hooked up to an EEG. What brain waves
guajiro [1.7K]

Answer:

The correct answer is option b. "Alpha eventually replaced by theta".

Explanation:

Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.

nordsb [41]

Answer:

The correct answer is option B) "computers are not as trustworthy as actual prototypes are"

Explanation:

It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.
