Reproductive pros and cons
An environmental shift or sudden outbreak of disease is most deadly to a population that reproduces this way.
Asexually
Wind-pollinated flowers lack these bright, colorful structures because they do not need to attract insect vectors.
Petals
This primary control organ processes incoming sensory info and coordinates a physical reaction.
The brain
Shivering and sweating are homeostatic mechanisms used to control this precise internal condition.
This large abdominal gland houses the specialized cells responsible for monitoring blood sugar levels.
The pancreas
This style of reproduction requires a massive energy investment to find, attract, and compete for a mate.
Sexual reproduction
The sticky top surface of the carpel designed to capture traveling pollen grains.
Stigma?
This structural component of the nervous system coordinates rapid reflex responses without waiting for the brain.
The Spinal Cord
In a negative feedback loop, this component processes the incoming data and determines the body's response.
The control centre
This direct transport system distributes hormones to target organs spread throughout the body.
The bloodstream (or circulatory system)
This specialized process of cell division produces gametes containing exactly half the regular number of chromosomes.
Meiosis
DAILY DOUBLE: This question is worth 1200 points (click twice if correct)
This structure supports the male anther, extending it outward to easily bursh against visiting pollinators
The Filament.
This category of neuron transmits signals away from the central nervous system to activate muscles or glands.
A motor neuron
This primary organ serves as the main control center for regulating human core temperature.
The brain (or the hypothalamus)
This metabolic condition occurs when the body can no longer properly produce or respond to the hormone insulin.
Diabetes
Budding and regeneration are rapid, but they limit a species' long-term survival due to a complete lack of this parameter.
Genetic diversity (or genetic variation)
The specialized plant structure that develops directly from the fertilized ovary and contains the seeds.
A Fruit
The specific gap between two neurons where chemical neurotransmitters pass messages along.
A Synapse
DAILY DOUBLE: This question is worth 1600 points (click twice if correct)
This specific type of loop amplifies or speeds up a biological process rather than reversing it
A positive feedback loop
This specific pancreatic hormone triggers the liver to release stored glucose when blood sugar levels drop too low.
Glucagon
Animals that invest heavy energy into a small number of offspring over their lifespan use this reproductive strategy.
High-quality strategy? (Or "K-selection")
Animal vectors like bees visit flowers primarily to gather these two energy-rich nutrient sources.
Nectar and pollen
These specialized biological units detect external changes like heat, pressure, or light.
Sensory receptors
When core temperature drops, blood vessels undergo this process to restrict blood flow to the skin and save heat
vasoconstriction
While the nervous system relies on electrical impulses, the endocrine system coordinates messages using this communication method.
Chemical messaging
