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.

CHOLESTEROL IS LIPID IN NATURE
LIPIDS ARE NOT proteins and cannot be SYNTHESIZED ON RIBOSOME

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.

how does a phenol red-containing solution look if co2 level is low?
Answer:
The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.
Explanation:
is this correct
A phenol red-containing solution with low CO2 level will appear red.
Phenol red is a substance that serves as an indicator. It changes in colouration in response to the acidity or alkalinity of solutions.
In acidic solutions, phenol red turns yellow while the colour is red in basic solution.
Solutions with high CO2 levels are acidic while those with little to no CO2 concentrations are basic.
Thus, in a low CO2 solution, phenol red will turn red and the solution will generally appear red.

Why is there gold on the inside of a cell phone but plastic on the outside
Answer:
Gold is chemically stable and conducts electricity.
Small pockets of gold are used to make mobile phone circuit board.
The plastic is lined to act as antenna gate. It's what makes a phone not a calculator but a communication point, since it allows the data flow, Bluetooth connection, Wi-Fi. Mainly, it allows radio waves to flow.
When the skydiver is falling at a constant velocity after the parachute is open, what is their acceleration?
Answer:
Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. ... The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
When the skydiver is falling at a constant velocity after the parachute is open, acceleration is zero.
The acceleration of the skydiver will be zero shortly after the parachute opens, but we can not call it as “acceleration due to gravity”.It's the acceleration due to gravity and air resistance together, and the forces cancel each other out to give an acceleration of zero.Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward.Learn more:

How long does it take Earth to make one rotation on its axis?
12 hours
48 hours
24 hours
Please answer ASAP
Answer:
24 hours
Explanation:
There are 24 hours in a day cause that is how long for the earth to spin on its axis
Answer:
24 hours
Explanation:
The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day.
It takes 40 mL of 0.10 M of hydrochloric acid (HCl) to neutralize 50 mL of sodium hydroxide (NaOH) for the following chemical reaction
HCl + NaOH → NaCl + H2O
The concentration of sodium hydroxide is _____.
0.125 M
0.08 M
0.10 M
0.04 M
Answer:
0.08 M
Explanation:
here...
1. water and a salt
2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.
3. titrant
4. 0.08 M
5. indicator
{quizlet: captncrun}
The concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
From the question,
We are to determine the concentration of sodium hydroxide
The given reaction is
HCl + NaOH → NaCl + H₂O
This means
1 mole of HCl is required to completely neutralize 1 mole of NaOH
To determine the concentration of sodium hydroxide,
We will use the formula
[tex]\frac{C_{A}V_{A} }{C_{B}V_{B}} = \frac{n_{A}}{n_{B}}[/tex]
Where
[tex]C_{A}[/tex] is the concentration of acid
[tex]C_{B}[/tex] is the concentration of base
[tex]V_{A}[/tex] is the volume of acid
[tex]V_{B}[/tex] is the volume of base
[tex]n_{A}[/tex] is the mole ratio of acid
[tex]n_{B}[/tex] is the mole ratio of base
From the give information
[tex]C_{A} = 0.10 \ M[/tex]
[tex]V_{A} = 40 \ mL[/tex]
[tex]V_{B} = 50 \ mL[/tex]
From the balanced chemical equation
[tex]n_{A} = 1[/tex]
[tex]n_{B} = 1[/tex]
Putting the above parameters into the formula, we get
[tex]\frac{0.10 \times 40}{C_{B} \times 50} = \frac{1}{1}[/tex]
Then
[tex]C_{B} \times 50 = 0.10 \times 40[/tex]
∴ [tex]C_{B}=\frac{0.1 \times 40}{50}[/tex]
[tex]C_{B}=\frac{4}{50}[/tex]
[tex]C_{B}=0.08[/tex]
Hence, the concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
