Which pathway is correct? proteins to RNA to DNA, DNA to RNA to proteins , RNA to DNA to proteins or DNA to proteins to RNA
Answer:
The sequence order should be DNA to RNA to Proteins.
Explanation:
For you to get the RNA sequence, you need to find a match for the DNA sequence. Your RNA sequence should only have either AUCG for your 4 nucleotide bases. Once you have the RNA sequence found by pairing it with the DNA sequence, you would then to do use an RNA codon chart to find the amino acids. These amino acids are basically your proteins.

If you initially have a volume of 4 L and a temperature of 300K. Then you decreased the volume to 2 L, what is the new temperature? Choose the appropriate gas law and use a calculator to complete the problem.
Answer:
T₂ = 150 K
Explanation:
Given data:
Initial volume = 4 L
Initial temperature = 300 K
Final volume = 2 L
Final temperature = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₂ = T₁V₂/V₁
T₂ = 300 K × 2L / 4 L
T₂ = 600 L.K / 4 L
T₂ = 150 K

What roles do valence electrons play in atomic bonding?
Answer:
Explanation:
Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom.
Hope this helps and mark brainlest i only have 1 :(
Valence electrons are the electrons in the outer shell of the atom, with the highest level of energy and that is where all of the chemical reactions and fun things happen.

3. Compare the alkali metals and alkaline earth metals with respect to:
i) Ionisation enthalpy
ii) Basicity of oxides
Answer:
Alkali metals are group 1 elements while alkaline earth metals are group 2 elements.
Ionization enthalpy is the energy required to remove the most loosely bound electron from an isolated gaseous atom. As the size decreases as we move from left to right in a period because the valence shell come closer to the nucleus as we move from left to right. Thus, the removal of electron from the valence shell becomes difficult due to greater attraction between nucleus and valence electron. Thus, the ionization enthalpy of alkaline earth metals is more than that of alkali metals.
Basicity of oxides decrease as the metallic character of the metal decreases. And as metallic character decreases on moving across a period. Basicity of oxides of alkaline earth metals is lesser than that of basicity of alkali metals.

Carbon and oxygen combine to form carbon dioxide. What are the reactants, or what
is the reactant, in this chemical reaction?
carbon dioxide
carbon only
oxygen only
carbon and oxygen
Answer:
The correct option is d: carbon and oxygen.
Explanation:
The reaction between carbon and oxygen to form carbon dioxide is:
C + O₂ → CO₂ (1)
On the left side of the above reaction (1), we have the reactants, which are carbon (C) and oxygen (O₂) that react to form carbon dioxide (CO₂), which is the only product of the reaction (on the right side of the reaction).
Hence, the correct option is d: carbon and oxygen.
I hope it helps you!
A flask containing a volume of 180 L of bromine was collected under a pressure of 35.5 kPa. What pressure would have been required for the volume of the gas to have been 80.0 L, assuming the same temperature? Which gas law did you need to use?
Answer:
P₂ = 80 KPa
Boyle's law is applied.
Explanation:
Given data:
Initial volume = 180 L
Initial pressure = 35.5 KPa
Final pressure = ?
Final volume = 80.0 L
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
35.5 KPa × 180 L = P₂ × 80.0 L
P₂ = 6390 KPa. L/ 80.0 L
P₂ = 80 KPa

5. How would a water molecule get from the ocean to the clouds ?
water at the surface of the ocean can become water vapor and move into the atmosphere with little added energy from the sun through the process called evaporation. The water droplets that form are what we call clouds
Answer:
Over 96% of total global water is in the ocean, so let's start there. Energy from the sun causes water on the surface to evaporate into water vapor – a gas. This invisible vapor rises into the atmosphere, where the air is colder, and condenses into clouds.
