2.7 - Cell division going wrong (Cancer), 2.9, 3.1 - The Hierarchy of structure in animals Flashcards
(13 cards)
2.7 - How is the behaviour of cancer cells different from normal cells?
Cancer cells grow and divide continuously and quickly, ignoring signals from the body. Normal cells respond to those signs.
2.7 - What’s carcinogen? (2 examples)
When an environmental factor causes cancer (sunlight and Tobacco smoking)
2.7 - 5 diagnostic techniques used to direct cancer
1) Endoscopy
2) X-ray
3) Ultrasound
4) CT scan
5) MRI
2.7 - 3 main conventional ways of treating cancer (Explain)
1) surgery: Physically remove cancer
2) Chemotherapy: With drugs
3) Radiation: Daughter cells are damaged by radiation and can’t be divided more
2.7 - 2 cancer screening tests young adults should do
pap test(for woman) and testicular self examination (for men)
2.9 - Why are complex organisms made up of specialized cells?
Because depending on the cell, it has a different function that work together to make sure living things can work properly.
2.9 - activities your body needs to do to stay alive (4)
1) fight diseases
2) digest food
3) breath
4) carry nutrients
2.9 - The DNA between one body cell and another are…
fairly similar and don’t have many differences
2.9 - Why do single celled organisms not show specialization?
That cell can do multiple roles on their own to keep the animal/plant alive. no specialization cuz only 1 cell
3.1 - What are the levels of organization in the hierarchy of structure in animals? -> (Example)
Organelle - cell - tissue - organ - organ system -organism
heart muscle cell - cardiac tissue - heart and blood vessels - circulatory system
3.1 - The simplest level of organization in any organisms is the ____. A group of ____ that work together create a _____. 2 or more _____ will create an _____. An _____ ______ is created as a result of 2 or more ____ that work together. 2 or more ______ ______ working together create and _____.
cell, cells, tissue, tissue, organ, organs system, organs, organ systems, organism.
3.1 - Give an example of an organism found in only 1 organ system and in more than one.
The stomach (Digestive system), Pancreas (Digestive/endocrine system)
3.1 - why are organ systems more complex than highly specialized cells?
It has multiple types of tissues working together to do specific functions for survival. Each organ system coordinates the activities of other organs for interactions.
