Answers

First let's start with the levels of organization. The levels of organization are atoms, molecules, cells, tissue, organs, organ system, and organism. Atoms and molecules are important to cell processes becuasse without them, there would be no celland there would be no cell processes, and in the end, there would be no organism.

Answer:

Proteins

Explanation:

Final answer:

Proteins are the biomolecules made up of the monomer 'amino acids'. They are composed of specific sequences of amino acids and are responsible for nearly every task of cellular life. Option 1

Explanation:

The biomolecule that is made up of the monomer 'amino acids' is Proteins.

Proteins are one of the basic components of living cells and are composed of specific sequences of amino acids linked together by peptide bonds. These sequences determine the unique three-dimensional structures which in turn determine protein function.

Consequently, proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.

One possible explanation for the fact that some simple, one celled organisms did not even evolve into complex multicellular organisms is that

Answers

The answer is that they have traits that enabled them to survive in a changing environment.

During the evolution of the Earth, and later during the evolution of life, the environment was not constant. Change in the environment could lead to an extinction of some species. But, some species were able to adapt or could tolerate a wide range of environmental factors. One of the explanation, why unicellular organisms did not evolve into complex multicellular organisms is because they have traits that help them to tolerate the wide range of factors, and thus, survive in changing environment.

According to evolutionary scientists, animals that arose later in evolutionary history share which characteristic?Flagellated cells

Cells organized into tissues

Radially symmetrical bodies
