The ecosystem is everything that exists in a particular environment.

Pleiotropic<span>: Producing or having multiple effects from a single gene. For example, the Marfan gene is </span>pleiotropic<span>, potentially causing such diverse effects as long fingers and toes (arachnodactyly), dislocation of the lens of the eye, and dissecting aneurysm of the aorta.

It is basically explaining the reproductive processes of fungi,
With sexual rep. and how it requires 2 sex cells to unite to produce spores that grow into new organisms
and then at the conclusion it states that most fungi reproduce asexually ( by itself )
and an example of how.
Answer:
The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.
Explanation:
Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.
To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a <u>polysome </u>and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.
