The correct answer is B) is equal to the number of protons in the nucleus of an atom of that element.
Explanation:
The atomic number, which is represented by the letter Z, refers to the number positively charged particles known as protons. This characteristic is key in chemistry and related areas because based on these features elements have different properties and are named. For example, an atom of nitrogen element always contains 7 protons, while one of the gold contains 79 protons. Moreover, this property is not related to the number of neutrons because atoms with the same atomic number might differ in the number of neutrons, which leads to isotopes of the same element.
Answer:
1. Ants, termites, and bees
Explanation:
Eusocial societies are common in insects. This type of behaviour is characterized by the fact that individuals fall into certain groups with certain behaviours. For example, think of worker bees and the queen bee. These societies are associated with a few features:
- the offspring are cared for by individuals other than the parents -many members in the group can cooperate to take care of the young.
- labour is divided into reproductive and non-reproductive groups. Only the reproductive individuals are able to have offspring, the others help with parental care, gathering food, and maintaining shelter.
- this creates groups, sometimes called 'castes', that animals fall into. They do not deviate from these groups once they are established.
This level of direct harvesting could cause the ecosystems to be severely damaged. The correct option among all the options that are given in the question is the second option or option "B". This type of fishing can disturb the natural balance and ultimately several species might vanish from our earth.
