In Environment A, trees are growing back and some of the larger animals are returning to a logged forest. In Environment B, lichens and moss are growing on a rocky mountainside that was scraped bare as a glacier retreated. Now, hundreds of years later, some small grasses, shrubs, and animals live there.

Which statement best describes both situations?

Environment A is undergoing succession, and Environment B is not.
Environment A is not undergoing succession, and Environment B is.
Both environments are undergoing the same kind of succession.
Both environments are undergoing succession, but different kinds.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

the answer is b.) hydrogen bonds between bases.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
