What is parthenogenesis?
Give this one a try later!
Asexual reproduction in some multicellular eukaryotes where females
produce eggs that are never fertilized by males, but divide by mitosis and
develop into fully grown individuals
What is asexual reproduction?
Give this one a try later!
Production of offspring that are genetically identical (clones) to the parent.
Doesn't require fertilization or mating.
,What are behavioral thermoregulation adaptations?
Give this one a try later!
Whether ectotherm or endotherm, it pays to move to areas with external
temperature optimum
- choose microhabitats (sun or shade)
- change body orientation relative to sun or to substrate
What are phototrophs & chemotrophs?
Give this one a try later!
Phototrophs: energy source from sunlight
Chemotrophs: energy from chemical compounds
The root system selectively moves minerals from the soil into the root cells using
__________ (3) and uses transpiration of water thru the xylem to transport these minerals
to the rest of the plant
Give this one a try later!
transpiration, active transport, and osmosis
T or F: Fungi do not have cell walls
Give this one a try later!
, False
What is mutualism?
Give this one a try later!
A symbiotic relationship in which both organisms live with each other and
benefit
Costs of endothermy:
Give this one a try later!
hugely energetically expensive (>50% of metabolic energy)
Unicellular organisms acquire and transport nutrients via:
Give this one a try later!
diffusion, AT, phagocytosis (euks)
What is the teeth structure for carnivores?
Give this one a try later!
, Carnivores like cats have large canines for gripping and killing prey
Plants are ________, while animals are ________
Give this one a try later!
photoautotrophs, chemoheterotrophs
Animals living in a hypertonic environment need adaptations to increase _____ and
decrease ______
Give this one a try later!
- water intake
- electrolyte intake
What is a hypertonic solution?
Give this one a try later!
A solution will a relatively high concentration of solutes
dissolved in it
Water rushes OUT of the cell from a low solute
concentration to a high concentration causing the cell to
shrink (crenation)
- Ex. saltwater is typically hypertonic relative to the cell
