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>

Len [333]
<span>it is Cardiac muscle tissue. Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heart’s mass. The heart beats powerfully and continuously throughout an entire lifetime without any rest, so cardiac muscle has evolved to have incredibly high contractile strength and endurance. And because the heart maintains its own rhythm, cardiac muscle has developed the ability to quickly spread electrochemical signals so that all of the cells in the heart can contract together as a team....</span>

The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)
Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

pH = -log[H_{+}]\\----------- Equation (A)

Where,

H_{+} = the concentration of hydrogen ion in the solution.

Given

H_{+}

= 0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\

Substituting the given value in equation (A) , we get -

pH = -log[10^{-4}]

= -(-4)\\= 4

Hence, The pH of a solution containing 0.1 mM H+ is 4
