What property of water allows for water to absorb large amounts of heat without changing temperature?
High specific heat
What are some examples of biotic factors?
- temperature
- (aquatic) pH
- population density
- Scarcity
- habitat loss
- competition level
- invasive species
Which lung contains three lobes?
the (anatomical) right lung
What are cyclins?
- a group of proteins that control the cell’s progression through the cell cycle/ replication
- bind to cyclin-dependent protein kinases enabling them to act as enzymes. These allow the cell to move from G1 to S and G2 to M at checkpoints.
What properties of water do the xylem of plants take advantage of?
cohesion AND adhesion
what does the word amphipathic mean?
- containing both hydrophilic and hydrophobic portions of a molecule
- creation of both polar and nonpolar properties in a molecule
How do detritivores make energy?
by eating small pieces of the remains of dead and decaying animals
What do type II pneumocytes do?
Secrete pulmonary surfactant
can replicate
What is oxidative phosphorylation?
- the process by which ATP is physically created
- ETC and chemiosmosis
- electrons are passed down a series of protein complexes, releasing energy that's used to pump protons across a membrane
- Chemiosmosis then uses the resulting proton gradient to drive ATP synthesis.
What is the cortex in plant anatomy?
Layer between epidermis and endodermis
Buffer layer for nutrient absorption from roots to xylem
what types of molecules, when consumed, cause increase in the number of high-density lipoproteins in the bloodstream?
- (trans)) unsaturated fats
How much energy is generally passed from one trophic level to another?
10%
what kind of blood vessels maintain narrow lumen and high pressure?
arteries
What do competitive inhibitors do?
bind to the enzymes’ active site instead of the substrate, making it unable to bind to a substrate (and therefore function)
What is the male reproductive organ in plants?
-stamen
- HDLs lower cholesterol levels in body
LDLs raise cholesterol levels in body
LDLs reduce number of HDLs in body
Which ecological pyramid shows the number of organisms in each trophic level of an ecosystem?
pyramid of numbers
What is fenestration?
pores cover capilleries to facilitate gas and nutrient exchange in the bloodstream
Which organelle is a part of the innate immune system and plays a large role in endocytosis?
-lysosomes
Where is the peduncle of flowers?
Stalk of flower
what does this photo show?
a condensation reaction
What element does NOT enter the atmosphere in its namesake cycle?
phosphorous
What occurs during the repolarization phase of a neuron's firing?
Positive to Negative change
Potassium channels open and potassium rushes out
During which structure do proteins become 3-D and structurally functional?
tertiary structure
What structure within the chloroplasts help with light absorption?
thykaloids
