The genome is the entire genetic material of an organism. The interaction with the environment develops an organisms phenotype.

B1.2 How is genetic information inherited?
When two gametes come together with 46 chromosomes. The genetic information stored in the chromosome becomes the offspring's.
2 of 12
B1.3 How can and should gene technology be used?
Genetic Testing can be used to improve healthcare, also help with family planning. Genetic Engineering can transfer a gene from a genome to another.
3 of 12
B2.1 What are the causes of disease?
Organism infected by pathogen, Mutation in Organism's genes, Environmental conditions, Trauma, Bad lifestyle.
4 of 12
B2.2 How do organisms protect themselves against pathogens?
The Human Immune System can attack pathogens by using white blood cells, to create antibodies that lock onto the antigen of the pathogen.

B2.3 How can we prevent the spread of infections ?
In humans; Being hygienic(washing hands), sterilizing wounds, living in sanitary conditions, destroying infected animals,vaccinations. In plants destroying infected plants,crop rotation

B2.4 How can we identify the cause of an infection?
We can observe the symptoms. With laboratory techniques we can count the amount of blood cells. View sample under a microscope, Growing the sample in culture, Or analysing the genetic material.
7 of 12
B2.5 How can we treat disease?
Painkillers, antibiotics, antivirals

B3.1 What happens during photosynthesis?
During photosynthesis, green plants and algae use energy from the sun to make glucose.

B3.2 How do producers get the substances they need?
Diffusion, Osmosis and Active Transport.

B3.3 How are organisms in an ecosystem interdependent?
All living things depend on their environment to supply them with what they need, including food, water, and shelter.

B3.4 How are populations affected by conditions in an ecosystem?
Populations can be affected by abiotic factors such as life intensity,temperature,water and pH levels.
