Biology Worksheet 1

The document discusses different cell structures including cell walls found in bacteria and fungi, nuclei found in fungi, and chloroplasts found in fungi. It then provides examples of structures that control movement into and out of cells, contain DNA, are involved in production of beer, and are made of chitin. Finally, it asks the reader to name different cell parts like the cytoplasm, cell wall, cell membrane, and vacuole.

When doing exercise, toxins are removed through sweating and constant exercise can reduce weight.
incomplete

Exercise needs energy in form of respiration. To make energy, glucose or fat reserves are broken down,
so it makes fat mass in body reduce giving out weight loss.
The gastric band makes the opening of the stomach smaller, as it is wrapped around stomach tightly.
This will reduce the amount of food intake of person, as the person would soon feel full. Reduction of
