Which of the following would not be made in a ribosome?
O enzymes
O cholesterol
O antibodies
O water-soluble hormones
Answer:
cholesterol(lipid)
Explanation:
Ribosomes are called PROTEIN FACTORY
Ribosomes are involved in protein synthesis
Any metabolite or substance protein in nature can be synthesized on ribosomes
enzymes are protein in natureantibodies are y shaped protective proteinswater soluble hormones are also amine or protein in natureSince they are protein in nature hence can be synthesized on ribosome.
WRONG OPTIONS:
CHOLESTEROL IS LIPID IN NATURE
LIPIDS ARE NOT proteins and cannot be SYNTHESIZED ON RIBOSOME
LIVER DOES THIS FUNTION OF CHLESTEROL SYNTHESIS.

We can use the formula M₁V₁ = M₂V₂ the total volume of water that will yield 0.800 M HCl. We can then subtract that from the initial volume to get how much water needs to be added.
Since M₁V₁ = M₂V₂ (starting mole× starting volume = end mole × end volume)
⇒ (5 mol)(20 mL) = (0.80 mol) V₂
100 mol/mL = 0.8 mol × V₂
⇒ V₂ = 100 mol/mL ÷ 0.8 mol
= 125 m
Since we began with 20.0 mL of water,
water needed to add = 125 mL - 20 mL = 105 mL

standardization is the process of titrating a solution prepared from
Standardization is the process of titrating a solution that is prepared from: a carefully measured solid mass to accurately find the concentration of titrant.
What is titration?Titration is also known as volumetric analysis (titrimetry) and it can be defined as a chemical process in which a solution of known concentration (titrant) is carefully and slowly added to another solution of unknown concentration, so as to determine the concentration or quantity of the analyte.
Similarly, a process referred to as standardization is used to titrate a solution that is prepared from a carefully measured solid mass to accurately find the concentration of titrant.

16 A particular light source gives off light waves with a measured wavelength of 2.0 x 10-7 m.
What is the frequency of the light source?
А 6.67 X 10-15 Hz
B 6.0 x 1011 Hz
с 1.5 x 1015 Hz
D Not enough information
Refer to the attachment
Light waves are part of the electromagnetic spectrum. The frequency of light therefore is 1.5 * 10^15 Hz.
What is light?
Light is an electromagnetic wave and we know that the speed of light is a constant which is 3 * 10^8 m/s.
Knowing this; v = λ * f
λ = wavelength
f= frequency of light
v = seed of light
f = v/λ
f = 3 * 10^8 m/s/2.0 x 10-7 m
f = 1.5 * 10^15 Hz

Calcium carbonate decomposes into calcium oxide and carbon dioxide when heated. Calculate the mass of carbon dioxide released when 300 g of calcium carbonate is heated.
Write a Balanced Equation for the decomposition
CaCO₃ → CaO + CO₂
Find Moles of CO₂ Produced
Since the mole ratio of CaCO₃ to CO₂ is 1 to 1,
the moles of CaCO₃ = moles of CO₂
moles of CaCO₃ = mass ÷ molar mass
= 300 g ÷ 100.087 g/mol
= 2.997 moles
∴ moles of CO₂ = 2.997 moles
Determine Mass of CO₂
Mass = moles × molar mass
= 2.997 mol × 44.01 g/mol
= 131.9 g
∴ when 300 g of calcium carbonate is decomposed, it produces 131.9 g of carbon dioxide.

what type of carbohydrates provide the body with a sustained release of energy?
Answer:
Fiber-rich, complex carbs
Complex carbs with fiber take much longer to digest than simple carbs. This helps to maintain stable blood sugar levels because sugar enters the bloodstream gradually . Complex carbohydrates provide sustained energy and help you feel fuller for longer because they are digested more slowly.
Which form of carbohydrates can your body use for energy?Glucose, also known as blood sugar, is the primary energy source for your body's cells, tissues, and organs. Glucose can be used right away or stored for later use in the liver and muscles.Carbohydrates are the body's preferred fuel source because they can be quickly converted to glucose. A light carbohydrate snack right before exercise is a good idea for quick energy. Eat protein with carbs to slow the rate at which your body absorbs them for longer-lasting energy.Fat is the most concentrated source of energy in the body, providing more than twice the potential energy of carbohydrate or protein (9 calories per gram versus 4 calories each per gram).To learn more about : Glucose

Bernice created a table using her knowledge of charged and uncharged objects. Which statement best explains why the table is incorrect?
Charged Object Uncharged Object
Negatively charged attract
Positively charged repel
The negatively charged and uncharged objects do not attract.
A positively charged object attracts an uncharged object.
Both positive and negative charges repel uncharged objects.
An uncharged object neither attracts nor repels charged objects.
Answer:B
Explanation:
A positively charged object attracts an uncharged object.
A positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.
What are charge?Charge are defined as a subatomic particle's ability to experience force when exposed to an electric and magnetic field. The value that the atom reaches after removing or gaining electrons is known as charge. Only ions that comply with the octat rule are stable. Atoms or groups of atoms with an electric charge are referred to as ions. Cations are positive-charged ion particles. Anions are ion types that have a net negative charge.
A charged object will cause an opposing charge to be applied to an uncharged object when it is brought close to the charged one. These two things are drawn to one another because opposing charges attract one another. Other charged items are drawn to a charged object whereas uncharged objects are repelled by it.
Thus, a positively charged object attracts an uncharged object statement is in correct in the table. Hence option B is correct.
