Because they have no competitors in any echological niche
Answer:
The correct characteristics are -<em><u> tissue, coelom, segmentation, endoskeleton, and backbone</u></em> from top to bottom boxes.
Explanation:
This phylogenetic tree showing the evolution and relatedness of the different organisms on their shared characteristics. In the given phylogenetic tree there are some characters are missing and we can predict or state them on the basis of evolution and studying the characteristics.
After the Porifera phylum tissue-level organization is found in the organism hence Tissue would be placed in the first box.
The coelom is found organisms above the Nematoda level, which further include a character segmentation in Annelida and Arthropoda. Another lineage from arising with the coelom organism that included endoskelton and backbone.
Thus, The correct characteristics are - tissue, coelom, segmentation, endoskeleton, and backbone from top to bottom boxes.
Answer:
Plants do resort to cellular respiration, wherein the products of photosynthesis are reunited to produce energy, which they have to do in order to convert the energy which is stored in the form of glucose into usable chemical energy.
The correct answer is D, water.
Answer:
Contour interval in surveying is the vertical distance.
Explanation:
Normally there are different contour intervals for different maps.The size of the area considers the contour intervals. In each and every map on the right hand bottom side the contour interval is specified.Therefore a contour interval is difference in two elevation between the contour lines in a topographical map
