3. The complexity of structure and function varies widely across the animal kingdom. Despite this variation, animals exhibit common processes. These include the following. • transport of materials
• response to stimuli
• gas exchange
• locomotion

(a) Choose two of the processes above and for each, describe the relevant structures and how they function to accomplish the process in the following phyla.
Cnidaria (e. g., hydra, jellyfish)
Annelida (e. g., earthworm)
Chordata (e. g., mouse)

(b) Explain the adaptive (evolutionary) value(s) of the structural examples you described in part a.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
