<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.
<u>Explanation:</u>
Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.
Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.
Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.
Answer:
when you dont enough water this is what would happens to your body
water is an essential for human life any deficit in normal body water though dehydration sickness exercise or heat stress can make us feel rotten. first we feel thirsty and fatigued and may develop a mild headache. This leads to various symptoms of dehydration including thirst and dry mouth, decreased urine output, muscle cramps, headache, lightheadedness, sleepiness and a lack of tear production. When the eyes stop producing tears, they are no longer properly lubricated, which can lead to dry eye, eye strain and vision problems.
