Reproductive Strategies
A group of living organisms consisting of similar individuals capable of exchanging genes or breeding fertile offspring
A species
The male reproductive cell (gamete) in animals
Sperm
the biological process where genetic information is passed down from parents to their offspring
Inheritance
This type of specialised neuron carries electrical impulses from sensory receptors towards the brain and spinal cord
The process by which the body maintains a stable internal environment despite external changes
Reproduction requiring only one parent that produces genetically identical offspring
Asexual reproduction
The female reproductive organ of a flower consisting of many carpel (stigma, style and ovary)
The pistil
This cell is formed immediately when a male gamete successfully fertilises a female gamete.
Automatic, rapid and involuntary response to stimulus that bypassess the brain to protect the body
Reflex
Hormones
Organisms like frogs or fish that lay thousands of eggs but provide no parental care. Utilising a certain strategy
This type of fertilisation occurs outside the females body, typically in aquatic environments
External fertilisation
The primary reason offspring from the same parents differ genetically from one another
Unique combinations/shuffling of parental genes.
The correct 5-step pathway of a nervous starting with the inital trigger (think, feedback loops)
Stimulus, receptor, brain (or spinal cord), effector, response
This organ or muscle brings about a change to reverse a disruption, acting as the final step in a feedback loop.
Effector
A type of asexual reproduction where an organism splits directly into two equal halves, common in bacteria
Binary fission
The specific part of the flower's stamen that produces and contains pollen
The Anther
The process by which one plants pollen grains are transferred to another to ensure genetic diversity
Cross-pollination
A simple classroom test that uses a falling object to measure how quickly the brain can process visual data and coordinate a response
This specific homeostatic mechanism works to minimize or reverse a change, bringing body conditions back to a set point
The major evolutionary advantage of sexual reproduction allowing a species better chance of survival in changing environments or with new diseases
Genetic Variation
Organisms use physical displays, songs or pheromones to achieve this critical pre-fertilisation objective
Attracting a mate
The stage in between approximately 2 weeks post-fertilisation to approximately 8-10 weeks post fertilisation (in humans) is referred to as the _______ stage. in this stage what structures form
Embryo, Major organs and basic body structures.
Signals that travel down a neurons axon to deliver messages rapidly across the body
Electrical Impulses
The two main hormones produced by the pancreas that work opposite each other to maintain healthy blood glucose levels.
Insulin and Glucagon
