1. Producing New Cells
It means they can become any type of cell.
What does it mean when a cell is referred to as pluripotent?
They are automatic, protective actions in response to stimuli.
What are reflexes?
In the oviduct.
Where does fertilisation take place?
They are different versions of a gene.
Because it means destroying an embryo.
Why is the use of embryonic stem cells controversial?
The 3 main parts of the brain.
What are the cerebrum, cerebellum, and medulla?
Pollen and ovules.
What are the male and female gametes in plants?
Variation that can be grouped into distinct categories.
What is discrete variation?
Tissue stem cells.
What type of stem cell can only differentiate into a few types of cell?
Carries electrical signal through the CNS to the motor neuron.
What does an inter neuron do?
It contains a food store.
Why is the female gamete (the egg) so much larger than the male (sperm)?
They are always expressed in the phenotype.
What is a key feature of dominant alleles?
To maintain diploid chromosome complement, to ensure correct function.
In Mitosis, why do daughter cells have to be identical?
Synapse.
What is the gap between neurons called?
What is the first cell produced afer fertilisation?
Because fertilisation is a random process.
Why are the actual ratios of traits in offspring not exactly the same as the predicted values?
Organs
Which layer in the hierarchy of organisation is made up of many tissues working together?
Endocrine system.
Name the system of organs which release hormones into the bloodstream for signalling.
Fertilisation.
What is the name for the process whereby the nuclei of two gametes fuse?
Always results in a 3:1 ratio of dominant to recessive traits.
What is the result of a monohybrid cross between two heterozygous individuals?
