Why is biodiversity in an ecosystem so important?
Because it can help humans where to determine good places to develop farm land.
Because places that have a healthy biodiversity are unaffected by major disturbances.
Because having a high biodiversity allows ecosystems to withstand major changes.
Because having a high biodiversity allows for fewer opportunities of competition for similar resources.
Two individual organisms that can breed together and produce fertile offspring are both members of the same ...

A wide range of chemical substances
What is the main function of the endocrine system?
It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.
It creates electrical messages that are sent around the body to maintain homeostasis.
It maintains the correct level of oxygen in the body to maintain homeostasis.
It releases waste from the body to maintain homeostasis.
What is going on in this animation?
Antibodies are attaching to a virus, keeping it from infecting a cell.
Viruses are attacking a normal cell.
The y-shaped things are gluons and they are directing a small cell to where it needs to go.
If you think about it, it makes sense that this word means "antibody generator".

antigen
pathogen
leukocyte
When you are sick, why might these parts of the body achy?
That's the circulatory system, where the white blood cells are.
The lymph nodes are where white blood cells are fighting pathogens.
Those are the places that the pathogen is targeting.

They do mitosis like crazy.
They put cells to sleep - or senecence.

How do you "win" at natural selection?
survive
get stronger than others in your species
survive & reproduce
What word describes a trait that helps an organism survive in its environment?
natural selection
mutation
camouflage
adaptation
Which of these is NOT a benefit of biodiversity in an ecosystem?
It helps all individuals survive
Some individuals will survive because they have different traits, even if lots of others in their species die.
If something kills off a whole species, others can take their place and the ecosystem is still OK.
More food sources for consumer species
