Bacterium that causes tetanus is an anaerobe but it has a blank before anaerobe

maybe?

Explanation:

Characteristics of Clostridium Tetani

Clostridium tetani is an obligately anaerobic bacillus that is gram positive in fresh cultures but may have variable staining in older cultures or tissue samples.25 The complete genome of the organism has been sequenced, and its products were recently compared with other clostridia.26 During growth, the bacilli possess abundant flagella and are sluggishly motile. Two toxins, tetanospasmin (commonly called tetanus toxin) and tetanolysin, are produced during this phase. Tetanospasmin is encoded on a plasmid that is present in all toxigenic strains.

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.
