Answer: 9 electrons
Explanation: In a neutral atom, it's important to understand that the atomic number or the number of protons that are stored in the core of that element will be the same as the number of electrons in the energy levels orbiting the nucleus.
So if an atom has 9 protons and it's neutral, the atom will have 9 electrons as well since the atomic number is your number of protons and electrons when the atom is neutral meaning it's not an ion.

The correct answers are the second and the fifth statements.
Explanation:
The non-native species are introduced in the community either as a consequence of human activity or because of natural range extensions. The majority of the non-native species exhibit deleterious ecological effects and are considered as invasive species. Almost all the ecosystems are at threat due to the deleterious effects of the introduced invasive species.
The non-native species are the prime threat to the surroundings as they can modify habitats and change the ecosystem services and function, and may replace or crowd-out the local species. The non-native species are considered as the second-ranked major threat to biodiversity after habitat destruction like deforestation.
These species threaten biodiversity as they can grow rapidly and can act as parasites or predators against the native species and do not possess any kind of natural predators so that the growth of the introduced species can be monitored. These species can act as competitors, as they compete with the local species for the resources available.

<span>The peritoneal organs such as the intestines, liver, stomach, and gall bladder are covered by the peritoneum. This is a membrane that supports the organs by allowing nerves, blood vessels, and lymph vessels to pass through the organs. Without membranes, the proper functions of these organs will be impossible.</span>
