Front

What is genetic engineering?

Back

Genetic engineering is the direct manipulation of an organism's genes using biotechnology, often to enhance desired traits.

Front

What are genetically modified crops?

Back

Crops that have been altered using genetic engineering to exhibit traits such as increased resistance to pests or improved nutritional content.

Front

What is genetic diversity?

Back

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species, which is important for resilience against diseases and environmental changes.

Front

What are analogous structures?

Back

Structures that have similar appearances or functions but do not share a common evolutionary origin.

Front

What are vestigial structures?

Back

Body parts that have lost their original function through evolution, such as the human appendix.

Front

What is the difference between bacterial and viral diseases?

Back

Bacterial diseases are caused by bacteria and can be treated with antibiotics, while viral diseases are caused by viruses and do not respond to antibiotics.

Front

What are viruses?

Back

Viruses are non-living infectious agents that can only reproduce inside a host cell.

Front

How do viruses attach to host cells?

Back

Viruses have projections on their surface that allow them to attach to specific receptors on host cells.

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite external changes.

Front

What is the role of antibiotics?

Back

Antibiotics are substances that kill or inhibit the growth of bacteria, but they are ineffective against viruses.
