The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).
What are ribosomes?Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.
Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.
The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.
Therefore, the correct option is (d) proteins.

In one to two sentences, describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).
Answers
Answer:
If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF's overall.
Explanation:
An experiment that would show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.
Intramolecular forces are the forces of attraction that hold atoms together within a molecule. Intramolecular forces require a high amount of energy to splits atoms or molecules in a chemical bonding.
Intermolecular forces are weaker forces of attraction that occur between molecules. They require lesser energy to splits molecules compared to intramolecular forces.
An experiment that show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.
In the process, the energy required to change the state from ice to steam water is more than intermolecular forces.
Thus, we can conclude that this experiment shows that the intramolecular forces are stronger than the intermolecular forces.

Tom pushes on a 50-kilogram box with a force of 25 newtons. Assuming the surface on which the box moves is frictionless, at what rate does the box accelerate?
Answers
Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 [tex]m/s^2[/tex].
Given the following data:
Mass of box = 50 kilogramForce = 25 newtons.To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;
[tex]Force = mass \times acceleration[/tex]
Making acceleration the subject of formula, we have:
[tex]Acceleration =\frac{Force}{mass}[/tex]
Substituting the given parameters into the formula, we have;

If the energy of the H–H bond is 452 kJ/mol. The energy of the O=O bond is 598 kJ/mol. The energy of the O–H bond is 367 kJ/mol, which bond would be the strongest? Which bond would be the weakest?
Answers
Taking into account the bond energy, the O=O bond is the strongest and the O–H bond is the weakest.
The bond energy is the average total energy that would be released by the formation of a mole of chemical bonds, from their constituent fragments (all in the gaseous state).
In other words, the normal or standard bond enthalpy is defined as the change in enthalpy or heat released, under standard conditions of 1 atmosphere and 25ºC, that accompanies the reaction of formation of one mole of bonds from the isolated atoms in gaseous state.
The higher the bond energy, the stronger and more stable the bond will be.
So, taking into account all the previous, the O=O bond is the strongest and the O–H bond is the weakest.

Each cart below is pushed across a room with the same amount of force. Which cart will result in the greatest change in speed?
F.A 75 kg cart being pushed with a 200 N force
G.A 125 kg box being pushed with a 200 N force
H.A 350 kg box being pushed with a 200 N force
J.A 450 kg cart being pushed with a 200 N force
Answers
The cart with the greatest change in speed is the cart with a mass of 75 Kg
Acceleration is defined as the change in velocity of an object with time. Also, acceleration is related to the force and mass according to the following equation:
Acceleration (a) = Force (F) / mass (m)
a = F / mTo answer the question, we shall determine the acceleration of each cart.
For cart of mass 75 kgMass (m) = 75 KgForce (F) = 200 NAcceleration (a) =?a = F / m
a = 200 / 75
a = 2.67 m/s²For cart of mass 125 kgMass (m) = 125 KgForce (F) = 200 NAcceleration (a) =?a = F / m
a = 200 / 125
a = 1.6 m/s²For cart of mass 350 kgMass (m) = 350 KgForce (F) = 200 NAcceleration (a) =?a = F / m
a = 200 / 350
a = 0.57 m/s²For cart of mass 450 kgMass (m) = 450 KgForce (F) = 200 NAcceleration (a) =?a = F / m
a = 200 / 450
a = 0.44 m/s²From the above illustrations, we can see that the cart with a mass of 75 K has the greatest change in speed (i.e 2.67 m/s²)

how would you expect the solubility of barium sulfate in pure water to compare to its solubility in 0.10 m nacl
Answers
Answer:
barium sulfate is insoluble (unable to dissolve) in water.
the general equation for the reaction between solid barium sulfate and nacl solution is this:
BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)
to sum this up, to compare the solubility,
1. barium sulfate cant dissolve in pure water.
2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.
good luck!
The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.
What is solubility?
Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.
Barium sulphate is insoluble in water beacuse it has higher lattice energy as well as higher size of cations & anions as compare to water, due to which water is not able to attract these ions towards itself affectively.Barium sulphate is soluble in the NaCl solution as this solution having ions which have more power to attract the ions of barium sulphate and show dissolution. Chemical reaction for this will be represented as:BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)
Hence, barium sulphate is insoluble in water.

Answers
Answer:

Explanation:
The dislocated electrons moving around the protons create opposite charges with electrostatic attraction between them that are very strong, and are called metallic bonds.
The particles in a metal are held together by strong metallic bonds . The metals forms crystalline solids with highly ordered lattice structure.
What are metals?Metals are electropositive elements. They are rich in electrons and easily donate their electrons with non-metals to form ionic bonds. Metals gain positive charge by losing electrons.
Metals in periodic table are classified as s block elements that are alkali metals and alkaline earth metals and d-block elements that are transition metals.
Metals forms highly ordered crystal lattice 3 D structures in which metal ions negative ions or electrons are bonded by strong intermolecular force called metallic bonds and the free electrons are located in the interstices.
These electrons can delocalize and conduct thermally and electrically.Hence, the bond which hold the particles in a metal is called metallic bond.
