• Crustacean, predator, scavenger

• Annelid, herbivore, burrower

• Echinoderm, filter feeder, sessile

Starfish

• Invertebrate that can fly

• Echinoderm, regenerates limbs

• Marine mammal known for intelligence

• Freshwater fish with vibrant colors

Cell Membrane

• Protects cell, controls entry/exit, present in Plant, animal and bacterial cell

• Provides energy to the cell

• Stores genetic information

• Synthesizes proteins

Molluscs

• Snails, clams, soft bodies

• Insects, arachnids, segmented bodies

• Fish, amphibians, vertebrates

• Worms, jellyfish, radial symmetry

Ribosomes

• Energy production in cells

• Protein synthesis, small structures

• Storage of genetic information

• Transport of nutrients

State any 4 ways through which diseases can spread

• Direct contact, Droplet Infection, break in skin, insect bite

• Contaminated food and water, exercise, fresh air, sleep

• Animal bite, lack of hygiene, stress, pollution

• Vaccination, healthy diet, regular exercise, sunlight exposure
