Answer:

$\boxed {\boxed {\sf A. \ Synthesize \ proteins}}$

Explanation:

The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: <u>protein synthesis. </u>

The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.

The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.

So, a ribosome is the main site for protein synthesis and the correct choice is A.

How could mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory

Ilya [14]

Mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory.

<h3>What do you mean by spontaneous generation theory?</h3>

According to the hypothesis of spontaneous generation, the emergence of life things from nonliving materials was both common and predictable. It was proposed that some forms, like fleas, may develop from inanimate substances like dust or that maggots could develop from decomposing human flesh.

In addition to causing postharvest rot during harvest and storage, a gray mold of tomatoes can also spread a number of other diseases, such as damping off and blight. A fungus with a host range of over 200 plants causes gray mold on tomato plants. It will be evidence for spontaneous generation theory.
