Animal Behavior & Ecosystems
What is animal behavior?
The ways animals interact with other organisms and the physical environment
What determines water potential?
The direction of water
What is speciation?
the formation of new and distinct species in the course of evolution
What is Immunology?
The branch of biology concerned with immunity
Which portion of a neuron receives neurotransmitters from a previous neuron, signaling the need for propagation of action potential?
Dendrites
What is a ecosystem?
A geographic area where plants, animals, and other organisms as well as weather and landscapes work together to form a bubble of life
Define cohesion
When water molecules and xylem saps create hydrogen bonds
What does speciation involve?
Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.
What is the function of the immune system?
It protects us from infection through various lines of defense
What is a neuron?
A nerve call that is specially adapted to generate electrical signals
How many biomes are there?
&
What determines solute potential?
When solutes are added to pure water and the concentration decreases
What is geographical isolation?
When a population is separated due to a geographical landmark
Who is the father of immunology?
What is the space between the neuron and its target cell?
Synaptic cleft
What is a producer?
An organism that produces its own food and energy
Why may stomata stay closed in bright lights?
For water conservation
What is sympatric speciation?
It is when reproductive isolation in an population occurs without geographical isolation
What is innate immunity?
It is the first line of defense and it is non specific
What is a synapse?
It is a cell to cell contact point
Why is behavioral research important?
It helps understand health and help fight disease. It can also help predict, prevent, and manage illness in whole populations
What controls the opening and closing of the stoma?
Guard cells
What is allotrophic speciation?
It is when a physical barrier separates a population and the separated populations adapt to their own new environments. They become so genetically different that they cannot breed with members of the other population
What is adaptive immunity?
It is the second line of defense that involves building up a memory of infections that have been encountered so it can create a response specific to the pathogen
Which of the following cells is found in the peripheral nervous system?
Schwann Cells
