Answer:
a cell wall (because a plant cell is less rigid than an animal cell)
- a large central vacuole (where plant cells store water)
- chloroplasts (which plants use to carry out photosynthesis)
Explanation:
Answer;
B. improved ecosystem health
Explanation;
-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.
-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;
- Habitat destruction
- Soil erosion
-
Air pollution from dust particulates
-
Pollution (especially from sediments)
-
All surface mining techniques negatively affect the environment, though some methods are more damaging than others.
Vinegar is an extremely acidic liquid. Very few microorganisms (ie bacteria and fungus which cause foods to spoil) can survive in such an acidic environment. Among other effects, it can destroy their cell walls, and prevent their own enzymes working (enzymes are extremely pH sensitive). There are a small number of microorgamisms which are adapted to survive in extreme acidity. However, this adaptation prevents them from surviving in more 'normal' environments. Therefore, anything which can survive in the vinegar, will not likely survive on your kitchen surface, and the same is true the other way around. Therefore, as vitually nothing can colonise whatever is in the vinegar, the food will be very effectively preserved. . . . . . . . . . . you can say........................ . . the low pH a nd high acidity of vinegar destroy bacteria
