Answer:The correct answer is chordates

Explanation:

Organism in the phylum Chordata develop dorsal nerve cord in their embryonic stage. Development of dorsal nerve cord is the characteristic feature of these animals and is developed by the mesoderm layer. In many of them they are only present in embryonic stage.

In vertebrates notocord disappears after completion of embryonic stage and is replaced by vertebral column which provide support and anchor to the  body structure of vertebrates.

Tunicates  are chordates and have dorsal nerve cord only in prenatal stage and it disappears in adults.

Like plants, human beings have similarities and differences. God gave us talents which He wants us to use. What can you do best?
asambeis [7]
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P

Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.

Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.
