Examples of bacteriophages are: 1) Temperate phages (mu and lambda) 2) Filamentous and spherical phages , both having ssDNA (single stranded DNA)
Answer: fat
Explanation:
Carbohydrates, fats and proteins are among the major nutrients in the food component.
- Where proteins helps in growth of the body where as carbohydrates and fat provide energy. Protein has 4 calories per gram.
- Carbohydrates are instant form of energy. All carbohydrates turn into glucose and raise our blood sugar. Carbohydrate has 4 calories per gram.
- While fats are the slowest source of energy but provides most energy. Each gram of fat provides about 9 calories [ approximately more than twice that in proteins or carbohydrates].
Hence, fat gives you the most energy .
I think the correct answer from the choices listed above is option D. A prokaryote that release energy if it is in an environment without oxygen and dies when exposed to oxygen, and uses fermentation would most likely be an obligate anaerobe. Obligate anaerobes<span> are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.</span>
