What are the key differences between vertebrates and invertebrates, and can you provide examples? Also, discuss the life cycles of different animals and skeletal functions.

Hey Omphile, good to see you again. Here are the answers to the questions from the image: 1. Look at the pictures below. a) What is the difference between vertebrates and invertebrates? Vertebrates have a backbone or spinal column, while invertebrates do not. b) For each animal, write down whether they are vertebrates or invertebrates. The animal on the top (deer/antelope) is a vertebrate. The animal on the bottom (crab) is an invertebrate. c) Identify the animal that has a skeleton with a frame structure. The animal on the top (deer/antelope) has a skeleton with a frame structure. d) Identify the animal that has a skeleton with a shell structure. The animal on the bottom (crab) has a skeleton with a shell structure. 2. What is the difference between the life cycle of a cow and the life cycle of a chicken? A cow undergoes direct development, meaning the young resemble the adults. A chicken undergoes indirect development with distinct stages like egg, chick, and adult, and it hatches from an egg. 3. Which part of the body is protected by the following parts of the human skeleton? a) The skull: The brain. b) The spinal cord: The vertebrae (or backbone). c) The ribcage: The heart and lungs. 4. How does a horse's skeleton help it to move? A horse's skeleton provides support for its body and leverage for its muscles, allowing for movement and locomotion. 5. Decide if each of these animals is a herbivore, a carnivore, or an omnivore: a) lion, monkey, zebra Lion: Carnivore Monkey: Omnivore Zebra: Herbivore b) Draw a food chain with three links that includes the herbivore and carnivore you identified in the previous question. Zebra Lion (This is a food chain with two links. If a third link is needed, it would typically be a producer like grass, e.g., Grass Zebra Lion). 6. Complete the following sentences with one of the words from the word box below: malleable, ductile, alloy, plated a) When a metal has been coated with another metal, we say it has been plated. b) We can beat or hammer metals into shapes because metals are malleable.
