Alcoholic fermentation occurs in yeast and produces ethyl alchol from pyruvate.
Lactic acid fermentation occurs in animals and produces lactic acid from pyruvate.
Both of these processes can proceed in the absence of oxygen.
The answer is B, because salt water has lots salt, and little water. The cells lose their water content and fill up with salt, causing ti to collapse.
Answer:
animals who eat the bark can spread it.
Explanation:
logic
A small amount of nitrogen is fixed by lightning, but most of the nitrogen harvested from the atmosphere is removed by nitrogen-fixing bacteria and cyanobacteria (formerly called blue-green algae). The nitrogen cycle transforms diatomic nitrogen gas into ammonium, nitrate, and nitrite compounds.
Answer:
- <u>Conventional plastics-</u>
"Plastics are typically organic polymers of high molecular mass, but they often contain other substances."
"Oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination.
- <u>Biodegradable plastics</u>-
"They are largely manufactured from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers."
Explanation:
<u>Complex Issue-</u>
- Diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all ‘good’ or petrochemical-based products are all ‘bad’.
- Biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.
