Answer: b. they accept a hydrogen molecule
Explanation:
NAD +: Nicotinamide Adenine Dinucleotide- Coenzyme that assists biological reactions by absorbing hydrogen atoms removed from the substrate. Its reduced form NADH or NADH2 contains more energy, which can be used to generate ATP in later reactions. Other examples of coenzymes used in the energy metabolism: FAD (Flavin Adenine Dinucleotide) and its reduced form FADH2
Limiting factors
for example: amount of food, water, shelter, predators, etc
Answer: I don't see any pictures...
Explanation:
In drinking water, the more turbid it appears, the higher the chance that those using it could end up with gastrointestinal diseases. The water may be having contaminants such as viruses and pathogenic bacteria which are found attached to suspended solids. These solids may interfere with disinfection of the water.
Erosion and effluent from highly urbanized areas contribute to the turbidity of water in those areas. In open bodies of water, organisms such as phytoplankton can contribute to turbidity in the water.
Answer: Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism.
