Nitrogen and oxygen make up about 99%of the atmosphere. I'm not sure if it will help! But thats all I know.
A sequence of biotic changes that regenerate or create an ecological community is known as ecological succession.
Ecological succession is the process of change in an ecological community's species composition over time. The time frame can span several decades or fewer (for instance, following a wildfire). The community grows through an increase in complexity from a small number of pioneering plants and animals to a stable or self-sustaining climax community.
Succession is a process that occurs after a disturbance or the early colonization of a new environment. It involves changes to an ecological community that are more or less predictable and orderly. Secondary succession refers to succession that occurs after a pre-existing community has been disrupted, whereas primary succession refers to succession that starts in new environments with no impact from pre-existing groups.

The term that describes the type of mutation is silent mutation, which is option B. Details about silent mutation can be found below.
<h3>What is mutation?</h3>
Mutation is any change in the nucleotide sequence of DNA molecule.
Mutation can be of different types as follows:
- Frameshift mutation
- Silent mutation
- Nonsense mutation
- Missense mutation
Silent mutation is the type of mutation that does not change the resulting amino acid.
According to this question, codon <em>GGU</em> is changed to <em>GGC</em> but they encode the same amino acid (glycine), hence, it is a type of silent mutation.

Answer:
Muscles contract rapidly to produce heat on a cold day.
Explanation:
Group 13-17 contains metalloids. Boron, Silicon germanium, Arsenic, Antimony, Tellurium and Polonium are considered metalloids. They have properties of both metal and non metal. Some of the element are good semi-conductors .
