Fires are an example of this type of limiting factor, one that happens to every species regardless of their numbers.
What is a density-independent factor?
A piece of DNA during mitosis and meiosis.
What is a chromosome?
One of the two types of natural selection leading to the neck of a giraffe.
What is positive (directional) selection?
Hormones destined for another cell are packaged at this organelle that looks like a breakfast food.
What is the Golgi Apparatus/Complex?
Wolves were introduced into this National Park in order to restore ecosystems after a trophic collapse.
What is Yellowstone National Park?
Foxes eat prey, an example of this type of limiting factor.
What is a density-dependent factor?
During Mitosis and Meiosis, centrosomes attach these sister pieces of DNA together.
What are chromatids?
Birds hang out on zebras to pick off bugs as a result of this ecological relationships.
What is mutualism?
Signal transduction starts with this step. Although the name implies it, there’s no ligand waiting room.
What is reception?
Although heterotrophs are known for using many food sources, this chemical is the most efficient.
What is glucose?
Extreme wildfires can cause this event, in which existing or new species rapidly fill ecological niches exposed after the burn.
What is Adaptive Radiation (or Succession)?
Chemiosmosis is important in this organelle.
What is the chloroplast?
Bugs in an African pond rely on surface tension, caused by this attractive force.
What is cohesion (hydrogen bond)?
Neural networks rely on this form of movement to move neurotransmitters from one cell to another.
What is exo/endocytosis (membrane trafficking)?
Producers are known by that name for production of glucose during this step of photosynthesis.
What is the Calvin Cycle (Light Independent Reactions)?
The Red Fox keeps rodent populations in check, and is a solid example of this ecological role.
What is a keystone species?
Gene expression is regulated by the relative accessibility of DNA during interphase, known as this.
What is chromatin?
The giraffe eats vegetation through herbivory. Plants grow replacement leaves by increasing the rate of what circular event?
What is the cell cycle?
Cellular signals can be autocrine, in which a cell signals to itself, to either increase or decrease a function, an example of this biological phenomenon.
What is feedback?
Decomposers break down materials into these building blocks, which have structural and chemical functions for all living things.
What are carbohydrates, amino acids, nucleic acids, and lipids?
Water puts out fire by absorbing the heat an example of this property of water.
What is specific heat/hydrogen bonding?
Pigments in plants can be separated into their individual components through this chart-worthy technique.
Chromatography
Elephants have large ears to dissipate heat and perform this form of temperature regulation.
What is endothermy (warm-blooded)?
Humans have evolved many types of the same cellular receptor through gene duplication. This is an example of what biological principle?
What is (evolutionary) fitness?
Pollution of ecosystems affects this property of food supplies. Nutrients are there, but they can’t be used.
What is bioavailability?
