Answer:
A. Lancelet
B. All chordates
Explanation:
A. Dorsal nerve chord is the only <u>unique feature</u> among all members of <u>phylum chordata</u> (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas <u>snail belongs to phylum Mollusca</u>, <u>grasshopper belongs to Arthropda</u>, and <u>jellyfish belongs to Cnidaria</u>.

The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
The answer is Starch molecules are larger than glucose molecules
The experiment show that the result of starch molecule test show higher concentration of carbohydrate than glucose. This show that the starch is made of multiple sugar. Because the starch is made of multiple sugar, it should be obvious that the size of the starch also bigger of the glucose.
they would die.... the two main things a plant need is water for the turgor to keep the upright and make sure it doesnt wilt and of course for photosynthesis
