Questions From Book Flashcards
Benefits of producing cloned plants from stem cells
Grow quicker and cheaply
Can save endangered plants from extinction
Can grow them with disease resistance
Why are stem cells cloned
To provide more of a certain cell
Why can’t all cells used to grow different types of cell
Due to body cells already being differentiated
What is therapidic cloning
Creating a cloned embryo for the purpose of producing embryonic stem cells with the same dna as donor cell
Benefit of using embryonic cloning
The stem cells won’t be rejected due to having the same genes
Why is Important in the osmosis practical that all root veg peices come from the same root veg
So that all veg has the same water concentration
What 2 variables should be kept constant in the osmosis practical
The volume of solution put inside bag
The temp of beaker
How are sugar molecules used inside cell
Respired to produce energy
Properties of the small intestine
Covered in villi-increases surface area for absorption
Good blood supply-maintains concentration gradient so absorption can happen quickly
Villi have single layer of surface cell
Short diffusion pathway
What’s the role of digestive enzymes in the process of digestive enzymes
Breaks down molecules unit smaller solubale molecules
Making them able to pass through the walls of the digestive system easier
Allowing to be ablatives into blood stream
