Which cell organelle is where proteins are made? A. nucleus B. ribosome C. vacuole D. mitochondrion

Answers

Answer: Ribosome

Explanation:

The protein formation inside the body takes place in the cell organelle named ribosome. Protein is a every essential component of the body.

It serves many functions in the body of all the eukaryotic organism. It is found on the body surface as the body guard to kill the invading pathogens, all the enzymes inside the body are protein.

The ribosomes inside the cell can be attached to the endoplasmic reticulum or can be found floating inside the cell.

The proteins are synthesized both by the floating and attached ribosomes. The proteins produced by the floating ribosomes are used inside the cell and the proteins made by rough Endoplasmic reticulum are most of the time sent outside the cell.

Answer:

B. ribosome

Explanation:

In the ribosomes, the codons get paired with anti codons to create a polypeptide or protein.

How many moles of carbon dioxide gas can formed formed the combustion of 4 moles of c5h14

Answers

Answer:

n CO2 = 20 mol

Explanation:

balanced reaction:

  • 2C5H14 + 17O2 → 10CO2 + 14H2O

∴ n C5H14 = 4 mol

⇒ mol CO2 = ( 4 mol C5H14)*(10 mol CO2/2 mol C5H14)

⇒ mol CO2 = 20 mol

Compared to the charge of a proton, the charge of all electron has(1) a greater magnitude and the same sign
(2) a greater magnitude and the opposite sign
(3) the same magnitude and the same sign
(4) the same magnitude and the opposite sign

Answers

Answer: option (4) the same magnitude and the opposite sign.

Justification:

1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals).


2) Protons are positive particles that are inside the nuclus of the atom.


3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom.


4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign: (+) + (-) = 0: positive + negative = neutral.

The charge of a proton and the charge of all electron has (4) the same magnitude and the opposite sign

Further explanation

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.

The charge of these three atomic particles is based on the Rutherford experiment. Rutherford experimented with firing alpha rays on a thin gold plate. From this experiment it was found that:

  • 1. Most alpha rays are passed through the gold plate, so it is concluded that most of the space in the atom has empty space
  • 2. A small number of alpha particles deflected shows there are positively charged particles inside the atom

(at this time these particles are called protons located in the atomic nucleus)

From here comes the Rutherford atomic model which states that atoms consist of positively charged particles (protons) and negatively charged electrons around the nucleus.

The charge of 1 proton is equal to a charge of 1 electron, but the sign is different.

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

Charge of 1 electron = e = -1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0
