The answer is <span> a strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus.
Electromagnetic forces are the cause why like charges repel and vice versa, why unlike charges attract. For an atom's protons to hold together and not to fly apart, there must be a force that is stronger than the electromagnetic force. Therefore, the </span><span>strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus. </span>
In order for some bacteria to grow, they need oxygen. These bacteria are called "aerobic" or "aerobes." Aerobic bacteria need oxygen to yield energy for growth. Most spoilage bacteria, molds, and yeast require oxygen to grow.
Some bacteria grow in oxygen-free environments and are called "anaerobic" or "anaerobes." An example of a common anaerobic foodborne bacteria is the Clostridium species, such as Clostridium botulinum and Clostridium perfringens. Some bacteria are facultative which means that they can grow in either the presence or absence of oxygen. Most foodborne pathogens are facultative with the exception of the above-mentioned Clostridium. Some are microaerophilic, meaning they grow in low concentrations of oxygen.
Sea lamprey in the aquatic Michigan food web is considered to be an invasive species. The sea lamprey will invade the ecosystem and will become competitors for food to the native predators. With more predators, natural preys will have a harder time for reproduction. The natural prey population will most likely decrease significantly, which could lead to their extinction.
