What are the inputs and outputs of cellular respiration? Write the equation.

-Sugar + Oxygen → Carbon dioxide + water + energy
-Sugar +O2 → CO2 + H2O + energy
-Inputs: O2 travels from the lungs to the mitochondria; Food travels from
the digestive system to the mitochondria
-CO2 leaves the cell & is expelled from the lungs
Explain what a keystone species is. Give an example from nature.

, -Term used for particularly strong interactors
-Species whose activities maintain species and habitat diversity and whose
effects are disproportionate to their abundance. Where the density of a
keystone species falls below some threshold, the species diversity in the
area may decrease, triggering ecological chain reactions, ending with
degraded or simplified ecosystems. Among such are large predators.
Keystone species can be thought of as having the highest per capita
interaction strengths
List an example of a cell in your body that undergoes mitosis. How many
chromosomes does that cell have? Is it haploid or diploid?
Give this one a try later!
-Skin cell
-Diploid = they have two copies of each chromosome
How does a plant get H2O? How does it get CO2?
Give this one a try later!
-H2O from the ground
-CO2 from the air
Why do the leaves on trees in our region turn red, orange, and yellow in autumn?
