MATERIAL WITH MOLECULAR INTERACTIONS
AND BIOLOGICAL SYSTEMS
◉ What are the three processes of natural selection?
Answer: The three processes are variation, inheritance, and
differential survival and reproduction.
◉ What is a tolerance response curve?
Answer: A tolerance response curve shows how an organism's
performance varies with environmental conditions.
◉ What is acclimation?
Answer: Acclimation is the process by which organisms adjust to
changes in their environment, such as temperature.
◉ How do ectotherms thermoregulate?
Answer: Ectotherms regulate their body temperature through
external environmental conditions.
◉ What is relative humidity?
, Answer: Relative humidity is the amount of moisture in the air
compared to the maximum amount the air can hold at that
temperature.
◉ What are trophic strategies?
Answer: Trophic strategies refer to the feeding behaviors and energy
acquisition methods of organisms.
◉ What is sexual selection?
Answer: Sexual selection is a form of natural selection where
individuals with certain traits are more likely to attract mates.
◉ What is a population in ecology?
Answer: A population is a group of individuals of the same species
living in a specific area.
◉ What are survivorship curves?
Answer: Survivorship curves graph the number of individuals
surviving at each age for a given species.
◉ What is carrying capacity?
Answer: Carrying capacity is the maximum population size that an
environment can sustain indefinitely.
