Answer:
The correct answer would be
- Concave lens for nearsightedness
- Convex lens for farsightedness
Nearsightedness or myopia is a condition in which a person can see the nearby objects clearly but is unable to see the objects present at a farther distance clearly.
It is usually caused due to elongation of the eyeball or when the lens becomes too curved.
It can be corrected by using a concave or diverging lens of appropriate power.
Farsightedness or hyperopia is a condition in which a person can see the distant objects clearly but is unable to see the nearby objects distance clearly.
It is usually caused due to shortening of the eyeball or when the lens loses its curvature.
It can be corrected by using a convex or converging lens of appropriate power.

stomata are the openings in a leaf
Translation requires some specialized equipment. Just as you wouldn't go to play tennis without your racket and ball, so a cell couldn't translate an mRNA into a protein without two pieces of molecular gear: ribosomes and tRNAs.<span>Ribosomes provide a structure in which translation can take place. They also catalyze the reaction that links amino acids to make a new protein.</span><span>tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as "bridges," matching a codon in an mRNA with the amino acid it codes for.</span>Here, we’ll take a closer look at ribosomes and tRNAs. If you're not yet familiar with RNA (which stands for ribonucleic acid), I highly recommend checking out the nucleic acids section first so you can get the most out of this article!Ribosomes: Where the translation happensTranslation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain.
