Another person has already given the definition of this. Here are the functions of a cnidoblast:
Used for defence from predators
Capturing prey
Each cell is ‘tagged’ by an organelle called the cnidocyst which has poisonous chemicals.
Explanation:
The orchid strategy can be best described as Postzygotic
I think pups? im not positive though :)
Vertebrates:
1) They've got a backbone/spine.
2) Are probably more complex organisms: fish, amphibians, reptiles, birds, mammals (in that order.)
3) Movement is based on an internal skeleton.
4) Wide range of sizes and shapes.
5) K-selected population
Invertebrates:
1) No backbone.
2) Less complex: sponges, worms, mollusks (e.g. snails) , crustaceans (e.i. crabs.) Insects.
3) Movement is not based on an internal skeleton, or some don't move at all.
4) Must be small in size to fulfill their needs for air and nutrients because systems are simpler.
5) R-selected population
The answers are satellites, weather balloons, and automated weather stations these are all correct because I just finished the test and checked.
