Answer by **PiNoY YFC**
okay I’ll try answering this:
1. Isn’t it obvious, an organism(bacteria) that is resistant to the activity of antibiotics

2. cytokinesis is the distribution of the cytoplasm into separate cells during cell division

3. photosynthesis is the chemical process of using light energy to combine carbon-dioxide and water to form glucose and oxygen

4. Simiarities – Presence of RNA, cell wall
Difference – virus have no organelles while bacteria have ribosomes
– virus have tail fibres while bacteria have flagella for movement

5. early bacteria(blue green bacteria) developed chromatophores that introduced oxygen into the atmosphere….i think ^_^

6. This is an obvious answer, just count the bactreia you observe under the microscope…lol

hope this helps ^_^

Answer by zeperboun
i could answer two of your questions.cytokineses is the division of cytoplazm after the telophase.photosenthesis is a very large issue but briefly;plants use co2 the light energy to produce glycosis and at the end of it;oxygen goes out.but there are so many reactions in photosenthesis which occurs in stroma and granum…if yo want to know i can give details.i couldn’T answer the other questions bec. am just a physics student not biology.i am sorry
