What is the number of species one finds in a certain area?
100
Contains various organs such as a reproductive shoot, axillary bud, petioles, apical buds, and lateral roots. Also contains dermal, ground, and vascular tissue.
What is a flowering plant
100
Define negative and positive feedback
What is a change in an initial condition that triggers a response to counteract the initial change.
What is the enhancing change triggered from environmental conditions.
100
The study of population and how it relates to the environment
What is ecology
100
The stabilization of population overtime due to population regulations (territory, predation, parasites)
What is carrying capacity
200
1. Individual variation in population
2. Individuals reproduce to form the next generation
3. Individuals pass on their traits to their offspring
4. Individuals differ in their ability to survive and reproduce
What is natural selection and describe its requirements
200
The difference between primary and secondary cell walls
Primary cell walls are found in parenchyma, sclerenchyma, and collenchyma cells. It is thin and flexible.
Secondary cell walls are found in sclerenchyma cells and allows durability, protection, and support.
200
Ductless organs that secrete hormones DIRECTLY into interstitial fluid
What is an endocrine gland (thyroid, parathyroid, ovaries, testes)
200
Explain how natural selection acts on existing variation
Dependent on conditions that currently suit the fittest organism. This stems from genetic recombination which alters the genetic make up of organisms.
200
Describes an environment with multiple organisms, and "r", or the rate of increase, changes overtime
What is logistic growth
300
Adaptive trait ex. Darwin's finches
What is inherited characteristics of an organism that enhance its survival and reproduction in a specific environment?
300
The movement of liquid in response to pressure gradients. Transpirational pull in the xylem is a result of the reduced tension as leaves transpire at an increased rate.
What is bulk flow
300
The myelination of neurons forces the continued movement of ions from one voltage-gated channel to the next to produce several action potentials.
What is saltatory conduction
300
Animal signals and communication
What is auditory, visual, chemical, and tactile
300
Colonization of a new habitat, with no history of occupation, following a disturbance.
What is primary succession
400
Homologous characters describe different species that came from a common ancestor. Homoplasious (analogous) characters describe different species that share a similar trait but is not caused by a common ancestor - caused by similar environments and adaptations.
What is the difference between homologous and analogous traits?
400
Wood makes up the _____ of the ______ cambium, while bark makes up the _____ of the ______ cambium
What is secondary xylem, vascular, secondary phloem, vascular
400
What are the main characteristics of the nervous system
Release electrical signals via neurons, response triggered by action potentials, fast stimulation, concentration gradient
400
Explain how predators are involved in the evolution of traits in prey
Prey must fight for survival, thus agility, size, number of offspring, toxins, & working together are key aspects of survival.
400
Human activities that threaten biodiversity
What are habitat loss, introduced species, overharvesting, & global change
500
Fungus provides the structure and nutrients, while the algae provides carbohydrates
What is the symbiotic relationship between an ascomycetes and photosynthetic microorganism such as algae
500
Describe the ploidy (haploid/diploid) of: gametophyte, sporophyte, spore, gamete, endosperm, and embryo
What is n, 2n, n, n, 3n, 2n
500
Identify and define each region of the nephron
What is the proximal tubule (reabsorbs water & nutrients, secretes hydrogen ions and ammonia), distal tubule (reabsorbs water & salt, secretes potassium and hydrogen ions), loop of henle (reabsorbs water and passively transports NaCl), collecting duct (carries filtrate to renal pelvis for later excretion)
500
The transfer of food energy up the trophic
levels from its source to various organisms. Give an example of each level of trophic interaction.
What is the food web.
Primary producer - plant
Primary consumer - fly
Secondary consumer - rat
Tertiary consumer - snake
Quaternary consumer - eagle
500
Change in population size as described by an equation
