Answer: I don't know if this helps but here's some information I think might help.
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.

What is true when an ion is formed?
A There is an unequal number of electrons and neutrons.
B There is an unequal number of electrons and protons.
C The atom loses one or more protons.
D The atom loses one or more neutrons.
Answer:
B There is an unequal number of electrons and protons.
Explanation:
There are two kinds of ion, cation, and anion. Cathion is when an atom loses electrons, which makes it have more proton than the electron. This makes the charge positive. Anion is the opposite of cathion. It's formed when an atom receives electron, thus making its charge negative. Because of this, there is no ion that has equal electron and protons.
Answer:
Presence of unlimited number of elements in the periodic table The inability of atoms to align perfectly with other atoms The ability of all elements to react with every other element All elements being equally reactive.
Answer:
Cystein, threonine and tryptophan can form hydrogen bond with progesterone
Explanation:
Those amino acids have -OH or H subunit in their side chain and these moities are very esential for hydrogen bond formstion with progesterone
A hydrogen bond can be said to be a partial intermolecular bonding between a lone pair on an electron rich donor atom, particularly highly electronegatine elements like nitrogen, oxygen, or fluorine and the antibonding orbital of a bond between hydrogen (H) and another more electronegative atom or group. Dotted or dashed line is always used to indicates the hydrogen bond.
Hydrogen bonding can also be seen existing between water molecules or hydrogen fluoride molecules since each molecule contains hydrogen bonded to a hyghly electronegative element.
