Ecological Level
The amount of light, temperature, and precipitation affect these large areas of the surface of the Earth. An example is that star fish usually live in the Neritic Zone.
What are biomes?
Some starfish are able to reproduce asexually but others go through a process that ends up with unique individuals. The laws that are related to chromosomes uniquely sorting themselves and that each gene gives only one allele. The laws are respectively
What are the laws of independent assortment and segregation.
Starfish can be put on charts that show it having bilateral symmetry, a complete gut, and then adding an endoskeleton as part of how it has changed over time. These charts are
What are dichotomous keys?
Starfish have a sense of touch, this is a type of what sense.
What is mechanical.
A tsunami comes and carries away most of a starfish population, this affect on them is an example of
What is density independent factors?
The total weight of starfish in a given area.
What is biomass?
Starfish do have a centralized brain but have the ability to sense light and a motor neurons to help maintain balance. This part of our nervous system is
What is peripheral nervous system?
Starfish change over time. This concept is
What is evolution?
Starfish neurons are able communicate through these areas between neurons.
What is synpases.
Starfish cells have an organelle that prevents things from coming or going out unless they selected to move through it. This is?
What is the plasma membrane?
Experimental removals of these species resulted in lower species diversity and allowed an herbivorous mussel to take over. Starfish are the most important species in an ecosystem.
What is keystone species?
While humans have used starfish for food, they are not a big enough demand to change their genetics so they would be a(n)
What is Genetically Modified Organism?
The names of the levels of classification are Eukarya Animalia Echinodermata Asteroidea Paxillosida Astropectinidae Astropecten duplicatus
What are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What are the 6 properties of water that allow starfish to live?
What is Universal solvent.
We could create a(n) --- if we knew how many starfish were alive at each possible age in a given population. They can live to up to 34 years.
What is population pyramid?
Some starfish coral reef habitats have been destroyed by humans. The coral reefs can grow back from nothing or if there is a little be left.
What is succession?
Depending on the species of starfish, some act aggressively and some retreat when covered in darkness. So a starfish senses darkness and then moves away from darkness until it is in the light. It sense the light and then it stops moving. This system is an example of
What is negative feedback?
There are four pieces of evidence that help tells us how a starfish evolved.
What are fossils, embryology, anatomy, biochemistry?
Starfish have adaptations that allow them to live in salt water, the solution of saltwater for starfish cells is a(n)
What is isotonic solution?
The phases of mitosis for starfish cells are
What is Prophase, Metaphase, Anaphase, Telophase.
Draw a nutrient cycle that includes Algae-->Mussels-->Starfish as part of the cycle.
Starfish rarely have out of control cell division that result in tumors spreading to different parts of their body. This would be
What is cancer?
Starfish have adapted to be able regrow their limbs. This must be an advantage to survive predatory attacks. They acquired this adaptation by individuals reproducing who could regrow larger and larger parts over generations.
What is natural selection?
The primary elements that make up starfish are CHNOPS. They are
What is Carbon, Hydrogen, Nitrogen, and Oxygen.
Who plays in Spongebob Squarepants as a starfish.
Patrick Star.
