Answer:

Deuterostomes include both phyla echinoderms and chordates, which includes the vertebrates.

Echinoderms and Chordates are more closely related to each other than they are to other animals because the coelom ( an open fluid-filled body cavity lined with tissues) found in the animals of this phylum is made from the digestive tube & the endoskeleton present in the body are composed of 95% of calcium carbonate just like present in chordates.

Which of the following best describes the influence of latitude on climate? A. Earth's climate zones are produced by the equal d

D. Polar regions receive less solar energy and heat per unit area than tropical regions 

Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
