The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
When dissolved in water, hydrogen ions are released from acids and hydroxyl ions are released from bases Good luck!
Explanation:
To put in a explanation. Biodiversity is needed to boost ecosystem productivity, allowing any species in the area to have an important role to play.
There are three types of Biodiversity
Genetic
Species
Ecosystem
Just use this info I gave you and put it all together
And here's an example.
A large number of species of plant, means more variety in crops. This is species diversity.
Sensory neurons in finger will start a chain reaction that is passed through the neurons from the finger tip all the way through the brain. The brain is then capable of interpreting the reaction and will immediately send response back through motor neurons capable of immediately moving the finger. Depending or the severity, swelling and bleeding may occur around the affected area.
