Answer:

Hypotonic solution

Explanation:

hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.

isotonic solution is the one you get when the solute concentration of the cell and the water are the same.

hypotonic is the one that you get when the solute  concentration of the cell is higher than that of the waters.

Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.

sorry if the grammer is bad i tried my best.

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide ch
HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.

<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

evablogger [386]
The synaptic pruning during childhood results in a reduction in density of nerve cells, thus increasing the brain's efficiency.
<span>Synaptic pruning, which can include both axon and dendrite pruning, is the process of synapse elimination that occurs usually in early childhood. It is thought that this is the brain’s way of removing connections in the brain that are no longer needed and a way of maintaining more efficient brain function.</span>
