Answer:
The answer to your question is: c) ATP
Explanation:
a) Carbon dioxide this molecule is a product of cell respiration so is very important for the cells but it isn't a form of energy cash, then this option is wrong.
b)Glucose: this molecule is used in the cell respiration process, from it the cell obtain ATP, but it isn't the energy cash for the cell.
c) ATP: this molecule is used by the cell to obtain energy, when an enzyme cuts off the phosphate bonds of this molecule it gets energy so this is the right answer.
d) Oxygen: oxygen is very important in the cell respiration process but It isn't usedas a energy cash.
Answer:
:)
Explanation:
If we subtract the atomic number from the atomic mass: atomic mass - atomic number = number of protons + number of neutrons - number of protons. Thus we get the number of neutrons present in an atom when we subtract the atomic number from the atomic mass.
All alcohols are polar.
True
The electromagnetic (EM) spectrum<span> is the range of all types of EM </span>radiation<span>. Radiation is energy that travels and spreads out as it goes – the </span>visible light<span> that comes from a lamp in your house and the </span>radio<span> waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are </span>microwaves<span>, </span>infrared light<span>, </span>ultraviolet light<span>, </span>X-rays<span> and </span>gamma-rays<span>. So it should be electromagnetic </span><span />
pH = 4.82
[H⁺] = 1.5 × 10⁻⁵ mol·L⁻¹.
pH = -log[H⁺] = -log(1.5 × 10⁻⁵) = 4.82
