The correct answer is B. Protons and electrons have the same mass.

Explanation:

An atom, which is the unit of mass, is composed of protons and neutrons that are in the nucleus, along with electrons that orbit the nucleus. In terms of mass, protons that are particles positively charged and neutrons that do not have a charge have the same mass that is around 1.67 x 10^{-27} Kg or 1 AMU (Atomic mass unit). However, in the case of electrons, these have less mass than protons or neutrons and the difference of mass is important as electrons have a mass of only 9.10 x 10^{-31} Kg or 0 AMU. Thus, the statement that is incorrect about atomic structure is "Protons and electrons have the same mass" because protons are much more massive than electrons.

Answer:

- Growing up means accepting oneself.

Explanation:

The theme of the given excerpt from 'The Outsiders' is 'growing up means accepting oneself' as it displays how the speaker has accepted his brothers' distinct choices and their way of life instead of imposing his own interests on them. His brother Soda does not 'crack a book at all' while Darrel, his eldest brother, remains busy with his work and doesn't have time for books, drawing, or movies but he seems to have accepted these differences in their choices. It reflects that with growing up, he's become more mature and accepting.

A text that lists benefits of owning a dog from least Importance to greatest importance uses___________ order.
sesenic [268]

Answer:

5. climatic

Explanation:

Arranging things in a sequence, where each things precedes or succedes another is called ordering. Ordering can be done in several ways, depending on ordering criteria.

For example, we can arrange events chronologically, which means we arrange them based on the time period when they occured; from the most to the least recent event, or vice versa.

Spatial arrangement means that we list things based on their position in space; from right to left, or from top to bottom.

Logical order is when we place things in a manner that each one logically follows the previous.

However, in this example, we have climatic order, which means that things are arranged in an order from the least important to the most important, making the final thing on the list the most important, or strongest, or the best.
