Answer 1

Answer:

1.When hands are soaked in water, the keratin absorbs it and swells. The inside of the fingers, however, does not swell. As a result, there is relatively too much stratum corneum and it wrinkles, just like a gathered skirt.

2.Slugs aren’t the fastest garden variety pests around, but they are persistent. As far as means for getting rid of them go, salt is still one of the best ways to keep slugs away from your prized cabbages. It’s not a great solution, of course, especially considering the fatal effects of such seasoning, but many folks don’t know of any other ways to get rid of slugs — even if there are many. Still, all other remedies notwithstanding, why does salt kill slugs?

3.Pickles, jams, jellies and squashes are kept in hypertonic solution of sugar or salt which causes the plasmolysis of bacteria and fungi. So, they cannot grow in such an unfavourable environment.
