Question 24 (1 point) Effects of Fungi
Fungus What it does
Mold Food spoilage
Ring worm Contagious skin disease
Athlete's foot Skin disease of the feet
Yeast Causes bread to rise
Salmonella Causes stomach illness

Laura and her lab partner were filling out a worksheet on microorganisms. The table they filled in was about microorganisms that were a type of fungus. "Wow! said Laura. "I didn't realize that all fungi were harmful!" "They are not!" said her partner. Is Laura's partner correct? Explain.
Question 24 options:

No. The fungi in the table al have harmful effects.

Yes. One fungus, yeast, causes bread to rise. That is helpful.

No. If you read the table all the fungi causes disease and illness.

Yes. Neither yeast that uses bread to rise or the mold that soils food is harmful.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
