Glycogenolysis and Gluconeogenesis occur in the liver due to the action of Cortisol.
It is the process of storing excess glucose for body which can be used at later time. the glycogen stored by the liver is broken down to glucose and dispersed in the body.
Cortisol helps to decrease insulin and increase glucagon. glucagon is type of peptide hormone secreted by pancreatic cells to increase the process of gycogenolysis or gluconeogenis. it is the primary stress harmone which increases glucose(sugar) in blood.
Gluconeogesis ia that process which tansform non carbohydrate substrate like amino acid ,gycerol into glucose.
Thus, Glycogenolysis and Gluconeogenesis occur in the liver due to the action of Cortisol.

Which statement describes the interactions of the magnets in terms of their magnetic fields
When the magnet on the right is moved toward the suspended magnet on the left, a repulsive force between the two magnets causes the suspended magnet to swing to the left; option B
What are magnets?Magnets are materials which exhibit magnetism or produces a magnetic field.
Magnets attract other objects to themselves and these objects are said to be magnetic.
Magnetic objects include metals such as iron.
A magnet has two ends called poles. The poles of a magnet are the North and South pole.
Magnetic lines of forces begin at the North pole whereas magnetic lines of forces end in at the south Pole.
The law of magnetism states that like poles of a magnet repel each other while unlike poles attract.
Considering the given magnets;
the magnet on the right is moved toward the suspended magnet on the left causing the suspended magnet to move to the left means that the end of the magnets repel each other.

Explanation:
The product is ammonium nitrate, with the chemical formula NH₄NO₃. This salt is composed of the cation NH₄⁺ and the anion NO₃⁻
Nitrate (NO₃⁻) is formed from the strong acid called nitric acid: HNO₃.
Ammonium ion (NH₄⁺) is formed from the weak base ammonia: NH₃.
Thus, the chemical reaction for the formation of the salt is the following:
HNO₃ + NH₃ ⇒ NH₄NO₃
If a sample originally had 410 atoms of carbon-14, how many atoms will remain after 16,110 years?
Answer:
58.4 atoms
Explanation:
To find the remaining amount of atoms, you need to use the half-life formula:
[tex]A = A_0*(\frac{1}{2})^{\frac{t}{h}[/tex]
In this formula,
-----> A = remaining amount (atoms)
-----> A₀ = initial amount (atoms)
-----> t = time passed (years)
-----> h = half-life (years)
The half-life is the amount of time that needs to pass for the initial amount of a substance to decay by 50% (or 1/2). According to the graph, 50% of the initial substance is left after 5,730 years.
A = ? atoms t = 16,110 years
A₀ = 410 atoms h = 5,730 years
[tex]A = A_0*(\frac{1}{2})^{\frac{t}{h}[/tex] <----- Half-life formula
[tex]A = 410*(\frac{1}{2})^{\frac{16,110}{5,730}[/tex] <----- Insert values
[tex]A = 410*(\frac{1}{2})^{2.81[/tex] <----- Divide 16,110 by 5,730
[tex]A = 410*0.142[/tex] <----- Raise [tex]\frac{1}{2}[/tex] to 2.81
[tex]A = 58.4[/tex] <-----Multiply 410 and 0.142

Which compound contains a higher percentage of oxygen by mass
Answer: [tex]TiO_2[/tex] has higher percentage of oxygen by mass.
Explanation:
To calculate the mass percent of element in a given compound, we use the formula:
[tex]\text{Mass percent of oxygen}=\frac{\text{Mass of oxygen}}{\text{mass of compound}}\times 100[/tex]
1. Mass of oxygen in [tex]TiO_2[/tex] = [tex]\frac{32g}{80g}\times 100=40\%[/tex]
2. Mass of oxygen in [tex]ZnO[/tex] = [tex]\frac{16g}{81g}\times 100=19.8\%[/tex]
Thus [tex]TiO_2[/tex] has higher percentage of oxygen by mass.
The compound with the higher percentage of oxygen by mass is titanium dioxide.
Titanium dioxide, TiO2, has a molar mass of 79.866 g/mol and O2 has a molar mass of 32.
Percentage by weight of oxygen in TiO2 = 32/79.866 x 100
= 40.07%
Zinc oxide, ZnO, has a molar mass of 81.38 g/mol
percentage by weight of oxygen in ZnO = 16/81.38 x 100
= 19.66%
Thus, titanium dioxide has a higher percentage by weight of oxygen than zinc oxide.

Assign an oxidation number to each element in the reaction
The question is incomplete, the complete question is;
Assign an oxidation number to each element in the reaction.
CO(g) + 2H2(g) → CH3OH(g)
In CO, the oxidation number of C is _, and that of O is _.
In H2, the oxidation number of H is _.
In CH3OH, the oxidation number of C is _, that of O is _, and that of H is _.
Answer:
See explanation
Explanation:
If we look at the reaction, in CO, C is +2 while O is -2. Remember that the sum of all the oxidation numbers in a compound must be zero.
The oxidation number of atoms in a diatomic molecule is zero hence in H2, H is zero.
We already know the oxidation states of oxygen and hydrogen in CH3OH to be -2 and +1 respectively. Carbon is;
x + 4(1) + (-2) = 0
x + 2 =0
x = -2
Hence in CH3OH, carbon has an oxidation state of -2.

What is the formula of tin (II) acetate?
Answer:
Sn(C2H3O2)2
Explanation:
C2H3O2 is Acetate
Sn is tin
Acetate has a -1 charge
In order for tin to have a +2 charge, we need two acetates
So we write it as (C2H3O2)2
You just leave Sn blank because of the roman numeral and since it is a transition metal.
So the answer is Sn(C2H3O2)2
Answer:
[tex]\boxed {\boxed {\sf Sn (C_2 H_3 O_2)_2}}[/tex]
Explanation:
First, find what tin and acetate is.
Acetate: C₂H₃O₂ Tin: SnNext, find the charge on acetate, which is -1.
The Roman Numeral 2 in parentheses after tin (II), signifies that the tin has a charge of +2.
We need to balance the charges, so they will equal 0.
1 acetate= -1 Tin = +2The best way to balance is by using 2 acetate molecules
2 acetate = -2 Tin = +2 -2 +2=0If we want 2 acetate molecules, we must add a subscript of 2 after acetate.
Acetate: C₂H₃O₂ 2 Acetate: (C₂H₃O₂)₂Add the tin (Sn) in front
Tin (II) Acetate: Sn (C₂H₃O₂)₂The formula for tin (II) acetate is Sn (C₂H₃O₂)₂

A student wants to measure the temperature of a solution. The student
takes 10 measurements and determines that the temperature is about 24.6 degrees celsius. If the true temperature is 24.3 degrees celsius, what is the absolute error in the measurement?
Answer:
0.3 or 0.30
Explanation:
The discrepancy between a quantity's measured or inferred value and its actual value is known as the absolute error. The absolute error is insufficient because it provides no information about the significance of the error. The absolute error is -0.3.
An important component of scientific calculations is measurement. Results from measurements that are entirely correct are incredibly unusual. Small mistakes are frequent while monitoring various metrics. Different kinds of errors result in variations in measurement. Mathematical equations can be used to express all faults.
The difference between a quantity's measured value and actual value is used to compute the absolute error. The absolute error is written as, if the measured value is x and the actual value is x₀.
∆x = x₀- x
∆x = 24.3 - 24.6
∆x = -0.3
