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.
Answer:
B. Release body heat
Explanation:
Jackrabbits live in deserts, and therefore must release excess body heat through the surface area of their ears to avoid quickly overheating and dying.
Answer:
Competition
Explanation:
Transportation of some molecules can not be through simple diffusion due to their size or other factors.
Therefore carrier proteins known as transporters are needed to facilitate their transportation.
Transporters exhibit or demonstrate characteristics such as competition,
During competition, presence of a certain molecule decreases the transportation of another molecule.
When Uric acid transportation is decreased due to the presence of probenecid is a good example of competition.
Hey there!
What you're looking for is spores.
Liverworts, mosses, and hornworts are non-vascular plants the reproduce by forming spores. They are basically little cells that multiply in order to reproduce.
I hope this helps! (:
I think scientific knowledge will be different in a 100 years (like robots could be taking employee jobs ummm... artificial trees maybe, VERY NEW AND IMPROVED TECH!
