| Question | Answer |
| When does immunisation happen ? | It is when your body has learnt how to produce antibodies needed to kill pathogens you had before |
| What is sexual reproduction ? | It involves the fusion of a male and female gametes. It produces genetically Different Calls ( two parents) |
| What is Asexual Reproduction ? | It is when there is only one parent. It produces genetically Identical Cells. |
| What is a cutting? | A cutting is a process where a good parent plant is cutted to produce genetically copies |
| What is Tissue Culture? | This is where a few plants are put in a growth medium with hormones and they will grow into new plants.Quick and grow all year |
| What is Embryo Transplant ? | It is a splitling that creates new embryos making many clones. Each is then be implanted into a surrogate mother. |
| Adult Cell Cloning | It is the production of true animal clones. They have the same DNA |
| How do Vaccinations work ? | They work against bacteria & viruses. Dead measles microbes are putted inside our body, the wbc produce antibodies that will quickly recognise and attack |
| What does MMR vaciine protect people against? | Measles, mumps & Rubella |
| How does immunity develop ? | It develops when your body has learnt how to make antibodies needed to kill a pathogen you had before |
| What is Sensory neurone ? | It's the nerve cells that carry signals as electrical impulses from the receptors to the cns. |
| Motor Neurone | It's the nerve cells that carry signals to the effector or glands |
| Effectors | Muscles and glands are known as effectors. Muscles contract in response to a nervous system |
| Tropism | Growth in response to stimulus |
| Phototropism | Plant grows toward the light |
| Gravitropism / Geotropism | When the plant growns in direction of gravity , the negative is when roots grow opposing gravity |
| Hydrotropism | Responses to water |
| Reflex Action | Stimulus-Receptor-Sensory Neurone- Relay Neurone- Motor Neurone- Effector- Response |
