Answer:

This question lacks options, the options are:

A The element is krypton, Kr, and it is not very reactive.

B The element is chlorine, Cl, and it is highly reactive.

C The element is krypton, Kr, and it is highly reactive.

D The element is chlorine, Cl, and it is not very reactive.

The correct answer is A

Explanation:

An atom is identified by its atomic number, which is the number of protons it contains. In this question, it is said that the atoms of a certain element each contain 36 protons. Using the periodic table, the element with atomic no. 36 is KRYPTON.

Also, Krypton posseses 8 valence electrons in its outer shell. In accordance to the octet rule, Krypton has no further need to engage in any chemical reaction to fill its electron shell because it is already filled (8 valence electrons). This accounts for the reason Krypton belongs to "Noble gases" and very unreactive.

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?
dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.
