We did an experiment in the lab and performances from each group
Materials: 3 slices of potato, water, salt, 1 graduated cylinder and 2 beakers.
Steps:
1. Feel the texture of the potato slices
2. Fill 1 beaker with 100 ml of water
3. Fill 1 beaker with 100 ml of water and 2 spoons of salt
4. Put 1 potato in water
5. Put 1 potato in salt water
6. Put one potato in air
7. Wait one hour
Results:
- Salt Water: Hard texture (hypotonic)
-Air: Normal (isotonic)
-Water: soft and mushy (hypertonic)

In class, Ms.Disty was explaining about eukaryote and prokaryote. Eukaryote is an organism consists of one or more cells each of them has nucleus in it such as plants, humans, and animals. Based on websites prokaryote is not bound within a nucleus, the DNA is less structured compared to eukaryotes. In Prokaryotes the DNA is a singleloop but in eukaryotes the DNA is organized into chromosomes. It says that bacteria is an perokaryotes.

At class we watched "I am Legend" it tells us about viruses that infected humans life and also we had category games about random things, the losers should dance chicken dance. We also had pre-assessment but when i saw the paper i understood nothing, So that's why we need biolit class! :D
