23. Enzyme A, as the temperature increases, the rate of reaction goes down. However, Enzyme B as the temperature goes up the reaction goes up.
24. Enzyme B is more active in a human cell, the reaction is what you want and everytime the temperature goes up in enzyme B the reaction goes up.
A polar molecule is when the arrangement of the atoms in molecules are unequal where one end of the molecule has a positive charge while the other end has a negative charge. Examples of a polar molecule are water, ammonia, hydrogen sulfide and sulfur dioxide. The opposite is called a nonpolar molecule.
Answer:
Explanation:
In CF4 and NF3, the valence electron groups on the central C and N atoms have a tetrahedral arrangement. The shapes of the molecules are determined by the number of bonding and nonbonding of electrons: since CF4 has four bonded atom(s) and zero lone pair(s) of electrons, the shape is tetrahedral.
The production of new skin cells is example of regeneration.
Regeneration is process of replacing or restoring not just skin cells, but also other cells in the human organism.
Skin regeneration is replacement of damaged tissue with new tissue.
There are two ways of skin regeneration:
1) reconstruction is a process of rebuilding of damaged skin cells
2) restoration is process of replacing broken cell skins
Epidermal stem cells are those who produces new daughter cell skins.
Epidermal stem cells are in the lowest layer of the skin.

#SPJ4
Answer:
6
Explanation:
This atom is sulfur (if the electrons are equal to the protons/not an ion). You can tell the number of valence electrons by looking at the individual shell. The first shell (1s) can only hold 2 electrons. The second shell (2s and 2p) can hold 8 electrons. The third shell (3s and 3p), which is the valence shell, only has 6 out of its possible 8 electrons, so this atom has 6 valence electrons.
