Answer:
In humans, up to ten different proteins can be traced to a single gene. Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren't all produced by all the body's cells at any given time. Cells have different proteomes depending on their cell type.
Explanation:
Proteins are macromolecules that are complex structures made of monomeric units. There are 20,000 - 60,000 different kinds of proteins in the human body.
What are proteins?Proteins have been the large molecules (macromolecules) that are structurally composed of the monomers or the smaller units. They have been composed of amino acids.
The amino acids are produced by the translational process and are linked by the peptide bonds. They are the most essential compound for the cellular and physical activity of the cells in living organisms.
The proteome is used to identify and classify the various proteins that can range from 20,000 - 60,000 in a human body. These proteins are involved in performing the functions in the body.
Therefore, approximately 20,000 - 60,000 proteins are found in the human body.

Answer:
where is the options
Explanation:
give options
Which of the following traits in inherited?
)piano skills
)strong muscles
)sun - bleached hair
)height
Sun-Bleached hair.
You can't exactly pass down piano skills, they have to be taught and also you can't just be born with strong muscles, they also have to develop over time. Height can't exactly be passed down because some parents are tall and their kids come out short. That leaves the only other option to be Sun-Bleached Hair (hair color).
Hope this helps and have a nice day.

A compound is made of 49.31% C, 43.79% 0 and the rest hydrogen. The molar
mass is 146.1g/mol, what are the empirical and molecular formulas?
(Show work)
Explanation:
49.31 + 43.79 = 93.10
finding the percentage of hydrogen in the compound hence 100-93.10 =6.9
therefore 6.9 percent of hydrogen is present in the compound
assuming that the compound is in 100 g so the elements present would be 49.31g of C , 43.79g of O and 6.9g of H
no. of moles of C = given mass÷molar mass
= 49.31 ÷ 12
=4.11 mol
no of moles of O = givem mass ÷molar mass
=43.79÷ 16
=2.73 mol
no. of moles of H =6.9÷1
=6.9 mol
dividing the no. of moles of each element by the least count of the elemnt to get the ratio of the simple whole numbr
therefore
so by dividing we get 1:1:2 of C:O:H
the empirical formula is CH2O
empirical formula mass of CH2O IS
= (12)+(2×1)+(16)
= 12+2+16
=30 G/MOL
n= molar mass of the compound ÷ empirical formula mass of the compound
so, n= 146.1 ÷30
n=5
molecular formula = n×empirical formula
molecular formula= 5×CH2O
molecular formula=C5H10O5 (ribose is the compound)
Lead (II) chromate, PbCrO4, was used as a pigment in paints. How many atoms are in 25 g?
Answer:
4.658 * 10^22 atoms
Explanation:
Mass = 25 g
Number of atoms = ?
Number of moles = Mass / Molar mass
Molar mass of PbCrO4 = 323.1937 g/mol
Number of moles = 25 g / 323.1937 g/mol
Number of moles = 0.077352993 moles
1 mol = 6.022 * 10^23 atoms
0.077352993 mol = x
Solving for x;
x = 0.077352993 * 6.022 * 10^23 / 1
x = 4.658 * 10^22 atoms
A compound MBr4 has a relative formula mass of 439
What is the relative atomic mass of M (Br=80)
Answer:
119
Explanation:
because the molecular mass of MBr can be found by adding the individual atomic masses of the molecule
Molar mass of M + 4(Molar mass of Br)= Molar mass of
MBr
Molar mass of M +4(80)= 439
Molar mass of M +320 = 439
Molar mass of M = 439 -320
Molar mass of M =119

All systems disperse their energy spontaneously?
Is it true or false? and WHY?
Answer:
True.
Explanation:
Yes, all systems disperse their energy spontaneously because all types of energy spontaneously flows from concentrated to dispersed if it is not hindered by any material in their way. Energy can be prevented from spreading by materials such as containers. If there is no substance in the path of energy so it can disperse automatically from a concentrated region to a lower region.

i need a short paragraph (about two sentences) describing the geologic time scale.
The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.
a container of gas has a pressure of 1.45 atm at a temperature of 52 degrees celsius, if the pressure increases to 4.2 atm what would be the final temperature of the volume is held constant?
Answer:
941 K (668°C)
Explanation:
We have the following data:
Initial pressure : P1 = 1.45 atm
Initial temperature: T1 = 52°C + 273 = 325 K
Final pressure: P2 = 4.2 atm
Final temperature: T2 = ?
The relation between pressure and temperature for a gas at constant volume is given by Gay-Lussac's law:
P1/T1 = P2/T2
That means that the pressure is directly proportional to the absolute temperature (in K). So, we calculate T2 from the equation:
T2 = P2 x T1/P1 = 4.2 atm x (325 K/1.45 atm) = 941 K
Therefore, the final temperature would be 941 K (668°C). This is consistent with the law, that states that if the pressure increase, the temperature will be increased.

What is the overall charge of an ion that has 11 protons, 13 electrons and 12 neutrons?
Answer:
+1
Explanation:
To calculate the charge on an ion, we simply use the number of protons and electrons. Protons are the positively charged subatomic particles. The electrons are the negatively charged particles in an atom.
When the number of protons are greater than that of electrons, the ion is positively charged.
When the number of protons are lesser than that of electrons, the ion is negatively charged.
When the number of protons and electrons are equal, the ion is neutral.
Answer Below and top
Charge = Protons - Electrons = 11 - 10 = +1

What is the meaning of the acceleration value 9.8 m/s?????
Answer:
The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth. The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.
All objects fall at the same rate of speed due to gravity, regardless of their weight. If a small grain of sand and a bowling ball are dropped at the same time, both hit the floor at the same time. The value of g varies by one's location on the planet, ranging from 9.782 m/s^2 in the Panama Canal Zone to 9.832 m/s^2 at the Noth Pole
