Collagen and Keratin, both fibrous proteins.
Aminoacids and proteins
Carbon and hydrogen are two elements that are essential for living things. They are found in molecules like carbohydrates, proteins, and fats that form the basic building blocks of life.

Two examples of living things covered in scales are snakes and fish. Both of these organisms have scales that help protect their skin and allow for movement in their environments.
Four classes of polymers found in living things are proteins, nucleic acids, polysaccharides, and lipids. These polymers play essential roles in various biological processes such as structure, storage, and energy production in living organisms.
Sulfur is found in living things in amino acids such as cysteine and methionine, which are important components of proteins. Sulfur is also found in vitamins such as biotin and thiamine, as well as in coenzymes like coenzyme A.
Biotic is one of two components in an ecosystem. Biotic factors are living things in an ecosystem such as animals
Plants and animals are two examples of living things that are eukaryotic. They have their genetic material enclosed within a membrane-bound nucleus and possess other membrane-bound organelles within their cells.
Two molecules found in living things that depend on hydrogen bonding for their structure and function are DNA and proteins. Hydrogen bonds play a crucial role in maintaining the structure and stability of DNA double helix and in the folding of proteins into their functional three-dimensional shapes.
Two characteristics of living things are the ability to grow and develop, and the ability to reproduce.
Two examples of non-living things in a grassland are rocks and soil. Rocks provide structure and may vary in size and shape, while soil is made up of minerals, organic matter, and nutrients that support plant growth.
The two qualities living things of the troposphere is the birds and humans so that living need to survive.
