Explanation:
Genetic mutation refers to the alteration of the sequence of bases in the gene of an organism. Recall that the gene contains sensitive information about the characteristics of an organism.
There are three types of genetic mutation which includes; base substitutions, deletions and insertions.
Using the analogy of the baker stated in the question, if he forgets to add something, then a part of the recipe has been deleted. This is analogous to the omission or deletion of a base in the sequence leading to mutation.
An additional or extra ingredient may be added to the recipe. This is analogous to insertion of a new base into the sequence leading to mutation.
If the baker adds a wrong ingredient instead of what he is supposed to add, this is analogous to substitution of a base by another leading to mutation.
In each of these cases, the taste of the cookies is marred. The baker can never produce the same taste of cookies exactly as described by the recipe book. This means that insertions, deletions and substitution of bases produce a new genetic code that is different from the original genetic code. This is referred to as genetic mutation.
Substances formed as a result of a chemical reaction are calledImmersive Reader (1 Point) products reactants catalysts precipitates
Answer: substances formed as a result of chemical reaction are called PRODUCTS.
Explanation:
A chemical reaction can be defined as a reaction in which substances known as the REACTANTS makes or breaks it's bonds to form another substance usually referred to as the PRODUCT. Usually, a new substance which is referred to as the product that is formed is different from the original reacting substances. Some of the characteristics of a chemical reaction include:
--> colour change,
--> heat production,
--> precipitation
The rate at which these chemical reaction occurs depends on some factors such as pressure, temperature and concentration of the reactants
There are different examples of chemical reaction which includes:
--> Rusting of iron: this occurs when iron and oxygen combines to form a mixture of iron oxides, which is the product of the chemical reaction.
--> The burning of magnesium in air: in this Chemical reaction, magnesium reacts with oxygen to form magnesium oxide which is the product of the chemical reaction.
2Mg(s) + O2(g) △→ 2MgO(s)
--> Production of table salt: this is formed from the reaction of sodium and chloride to give sodium chloride as the product of the chemical reaction.
Therefore in a chemical reaction, no atom is destroyed or created but a new PRODUCT is formed from reactants.
A 72.4 mL solution of Cu(OH) is neutralized by 47.8 mL of a 0.56 M H2(C204) solution. What is the concentration of the Cu(OH)?
Answer: The concentration of [tex]Cu(OH)_{2}[/tex] is 0.369 M.
Explanation:
Given: [tex]V_{1}[/tex] = 72.4 mL, [tex]M_{1}[/tex] = ?
[tex]V_{2}[/tex] = 47.8 mL, [tex]M_{2}[/tex] = 0.56 M
Formula used to calculate the concentration of [tex]Cu(OH)_{2}[/tex] is as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]
Substitute the values into above formula as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}\\M_{1} \times 72.4 mL = 0.56 M \times 47.8 mL\\M_{1} = \frac{0.56 M \times 47.8 mL}{72.4 mL}\\= 0.369 M[/tex]
Thus, we can conclude that the concentration of [tex]Cu(OH)_{2}[/tex] is 0.369 M.

How many moles are in 8.0 gram sample of C3H4
Answer:
0.18 mol C₃H₈
Explanation:
to find the mole you have to convert the 8.0grams into moles.
8.0g C₃H₈ 1 mol C₃H₈
1 44.0g C₃H₈
*Pretend that those are a table*
I got 44.0g because Carbon is 12.0g you multiply that 3 times because it has a subscript of 3 and do the same for Hydrogen (1.0 x 8) then add those which would be 44.0g.
1 mol of C₃H₈ = 44.0g C₃H₈
now just mulitply and divide them.
8.0g x 1 = 8.0
1 x 44.0g = 44.0
8.0/44.0 = 0.18 mol C₃H₈

A 32.9-mL sample of Ba(OH)2 is titrated with HCl. If 37.2 mL of 0.863 M HCl is needed to reach the endpoint, what is the concentration (M) of the Ba(OH)2 solution
Answer:
[tex]M_{base}=0.488M[/tex]
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by firstly writing the chemical reaction between hydrochloric acid and barium hydroxide:
[tex]2HCl+Ba(OH)_2\rightarrow BaCl_2+2H2_O[/tex]
It means there is 2:1 mole ratio of the acid to base, and we are able to write the following mole ratio, then written in terms of volumes and concentrations:
[tex]n_{acid}=2n_{base}[/tex]
Thus, we obtain the following:
[tex]M_{acid}V_{acid}=2M_{base}V_{base}[/tex]
Then, we solve for the concentration of the base and consequently plug in the given data to obtain:
[tex]M_{base}=\frac{M_{acid}V_{acid}}{2V_{base}} \\\\M_{base}=\frac{0.863M*37.2mL}{2*32.9mL}\\\\M_{base}=0.488M[/tex]
Regards!

Which substance is a type of biomolecule that can be used for energy storage and insulation? O A. Nucleic acid O B. Carbon dioxide O C. Lipid D. Protein
Answer:
Protein
Explanation:
Protein is used to make insulation (like fat) and is used to store energy taken form food (please tell me if this works)
Protein which is made up of amino acids is a type of biomolecule that can be used for energy storage and insulation.
What are amino acids?Amino acids are defined as the substances which are considered to be the monomers of proteins.Every amino acid has the same structure consisting of a central carbon which is bonded to an amino group , carboxyl group and a hydrogen.
Each amino acid also has another atom or a group of atoms bonded to the alpha carbon which are also known as the R group or the variable group of the side chain.There are 20 common amino acids present in natural proteins and each amino acid has the same backbone.
The sequence and number of amino acids determines protein's shape,size and also its function. Each amino acid is attached to the other by a covalent bond formed by a dehydration reaction.

Se disuelven 10 g de acido carbónico H2CO3 en 150 g de agua. Determina la concentración % m/m de esa disolución?
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100[/tex]
Substitute the values into above formula as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100\\= \frac{10 g}{150 g} \times 100\\= 6.66%[/tex]
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.

The cells of a tomato contain mostly an aqueous solution of sugar and other substances. If a typical tomato freezes at -2.5 °C, what is the molality of the sugar in solution? (Hint: sugar is a covalent compound, it does not dissociate in water)
Answer:
1.35 m
Explanation:
We can solve this problem by using the freezing point depression formula:
ΔT = Kf * m * iWhere:
ΔT is the temperature difference between the freezing point of the pure solvent (water) and the solution. In this case it is (0 °C - -2.5 °C = 2.5 °C).Kf is the cryoscopic constant, for water it is 1.853 °C*kg/mol.m is the molality.i is the van't Hoff factor, as sugar does not dissociate in water, it has a value of 1.We input the data:
2.5 °C = 1.853 °C*kg/mol * m * 1And solve for m:
