What prior knowledge is necessary before balancing a chemical equation?​

Biology
1 answer:
Yanka [14]2 years ago
6 0

Answer:

At first, we should know their molecular formula and symbol. In case of element, symbols are written. But in case of compound, molecular formula is used. Also we should know their coefficient (number) to make the number of atoms either side equal.

If a blood cell is placed into a solution of 10M salt (highly salty) what would you expect to occur?
steposvetlana [31]
The blood cell will lose water and will undergo lysis.

Cell membrane is permeable to water and can get/lose water via osmosis. Osmosis is induced by the gradient of concentration of the solution. In this case, the 10M salt solution has a very high oncotic pressure that it will attract nearby water. That means the water inside the cells will be taken into the solution and cell will continue to shrink and then die.

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.
kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4)  tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.
