Biology Flashcards
What are in Animal Cells?
Cell Membrane, Nucleus, Mitochondria, Cytoplasm, Ribosomes
What are in Plant Cells?
Cell Membrane, Nucleus, Mitochondria, Cytoplasm, Ribosomes
What is DNA?
The molecule that contains the instructions for growth and development of all organisms.
What is reproduction?
Reproduction is the production of offspring by a sexual or asexual process
What’s sexual reproduction?
Sexual reproduction is genes from two parent organisms which are combined to produce an organism with a unique genetic code.
How much chromosomes do meiosis create?
Meiosis create 23 chromosomes
What is cystic fibrosis?
Cystic fibrosis is a disorder that damages your lung, digestive tract, and other organs. It’s an inherited disease caused by a defective gene that can be passed from generation to generation.
What is polydactyls?
It’s a condition where a person has more than five fingers or toes on one or both hands or feet.
Polydactyl
Polydactyl can either be a dominant or recessive trait, depending on the cause. If polydactyls is caused by a single gene mutation, it’s usually a dominant trait, meaning that one parent can pass it onto their child with a 50% chance.
What is mitosis?
Mitosis produces two genetically identical daughter cells from a single parent cell
What does meiosis produce?
Meiosis produce cells that are genetically unique from the parent and contain only half as much DNA.
What are fossils?
Fossils are the remains of plants and animals from many thousands of years ago that are usually found in rocks.

Samonella Gonorrhoea
Viral disease example
Measles
HIV
Fungal diseases example

Vaccination how do they work
Small quantities of dead or inactive forms of pathogens into the body to simulate the white blood cells and produce antibodies.
Communicable disease
Infectious
Human defence systems
Skin, nose, trachea and bronchi, stomach
What is the cell cycle
- They divide to make new cells
- This is called mitosis
