Module 5
A process where gametes are fused outside of the parent organism.
What is external fertilisation?
A change in DNA in one specific location.
What is a point mutation?
Pathogens such as viruses or prions.
What are non-living pathogens?
A constant, stable internal environment.
What is homeostasis?
A feature of an experiment that remains constant.
What is a controlled variable?
When two dominant alleles are expressed, they create a phenotype where both alleles are simultaneously expressed.
What is codominant inheritance?
Mutations that occur before cell differentiation, and mutations that occur after cell differentiation in gamete cells.
What are somatic and germ-line mutations?

What is crossing over of homologous chromosomes?
A consideration related to the well-being and health of animals, people, or plants.
What is an ethical concern with Biotechnology?
A form of treatment which acts to prevent protein synthesis and cell-wall synthesis of certain pathogens.
What are antibiotics?
Through methods such as a thick waxy cuticle, curling of leaves, and shrunken stomata.
How do plants maintain water balance?
One type of data reference involve numbers and the other includes description
What are qualitative and quantitative references?
Genetic material with minimal repetition, few introns, and roughly 160,000 to 12 million base pairs.
What is prokaryotic DNA?
These are the three main factors that affect the gene pool of a population.
What are mutations, gene flow and genetic drift?

What is the formulae to calculate prevalence rates?
A lens used to treat individuals with hyperopia.
What is a convex lens?
A type of graph that is used to represent categorical data.
What is a column graph?
A collection of 32 cells after 5 days post-fertilisation.
What is a blastocyst?
A scientific process scientifically known as somatic cell nuclear transfer.
What is whole organism cloning?
These are four types of cells associated specifically with the cell-mediated response.
What are cytotoxic, memory, helper and supressor T cells?
Significant time period, large sample size, control group, maintenance of variables, appropriate data collection, comparison to similar data of other studies.
What are criteria for a valid epidemiological study?
This is improved by maintaining variables and using an experimental control.
What is validity?
