Name three instructions that DNA provides to a cell
Answer:
The instructions in a gene that tell the cell how to make a specific protein. A, C, G, and T are the "letters" of the DNA code; they stand for the chemicals adenine (A), cytosine (C), guanine (G), and thymine (T), respectively, that make up the nucleotide bases of DNA.

DNA contains the commands that an organism requires to develop, survive, and reproduce. DNA sequences must be transformed into messages that can be used to make proteins, which are the complex molecules that do the majority of the work in our bodies, in order to perform these functions.
What is DNA?Deoxyribonucleic acid is a polymer consisting of two polynucleotide chains that coil into one another to form a double helix.
It contains genetic information in the form, fully operational, growth, and reproduction of all kinds of organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
DNA stores information as a code composed of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
DNA contains all of the instructions that an organism needs to develop, survive, and reproduce.
To perform these functions, DNA sequences must be transformed into messages that can be used to make proteins, which are the complex molecules that do the majority of the work in our bodies.
Thus, these are some of the instructions that DNA provides to cell.

What is the mass and volume of the nucleus relative to the size of the atom?
Answer:
The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.
What are valence electrons? The number of neutrons in a nucleus. The number of protons in the nucleus. The atomic mass is the same as the number of valence electrons. The number of electron in the outer most shell of an atom.
Valence Electrons are The number of electrons in the outer most shell of an atom. These shells have a maximum amount before being filled by electrons, in which remaining electrons will fill the next remaining valence shell.

Answer:
Even though plants are rooted in the ground, they still move, exert force, and do work.
Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.
When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.
When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

0.45 g of hydrated sodium carbonate crystals were heated until 3.87 of anhydrous power remained.
How many moles of water are there in one mole of hydrated salt?
Formula of hydrated sodium carbonate : Na₂CO₃.10H₂O, so moles of water in one mole of hydrated salt = 10
Further explanationHydrate is a compound that binds water (H₂O), usually in the form of crystals/ solids
If these compounds are dissolved in water or heated, the hydrates can decompose:
Example: X.YH₂O (s) → X (aq) + YH₂O (l)
The formula for the hydrated compound contains: YH2O
The mole ratio shows the ratio of the coefficients of the hydrate compound
10.45 hydrated sodium carbonate(Na₂CO₃.xH₂O) were heated until 3.87 of 3.87of anhydrous (Na₂CO₃) remained, so
mass H₂O released :
[tex]\tt 10.45-3.87=6.58~g[/tex]
mass Na₂CO₃ = 3.87 g
mol ratio Na₂CO₃(MW= g/mol) : H₂O(MW=18 g/mol) =
[tex]\tt \dfrac{3.87}{105,9888}\div \dfrac{6.58}{18}=0.0365\div 0.3655=1\div 10[/tex]

In 17.2 seconds, a shopping cart is pushed 15.6 meters towards the west. What is the velocity of the cart? (hint~The answer is NOT 3m/s)
Answer:
0.91m/s due west
Explanation:
Given parameters:
Time taken = 17.2s
Displacement = 15.6m
Unknown:
Velocity of the cart = ?
Solution:
Velocity of a body is the the displacement divided by the time taken.
Velocity = [tex]\frac{displacement}{time}[/tex]
Now insert the parameters and solve;
Velocity = [tex]\frac{15.6}{17.2}[/tex] = 0.91m/s due west

How many moles are in a sample of 9.47 x 1024 atoms of argon (Ar)? (Show your calculations for full credit. Correct answers will only receive partial credit.)
Your answer:
Answer:
15.73 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{9.47 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.730897...[/tex]
We have the final answer as
15.73 molesHope this helps you
Answer:
15.7 moles of Ar
Explanation:
Given data:
Number of atoms = 9.47 ×10²⁴ atoms
Number of moles of Ar = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
9.47 ×10²⁴ atoms × 1 mole / 6.022 × 10²³ atoms
1.57×10¹ mol
15.7 mol
