m_a_m_a [10]

Answer:

-often function as enzymes or transport proteins  ⇒ globular proteins

-peptide chains arranged in long strands, or fibers  ⇒ fibrous proteins

-peptide chains highly folded into spherical shapes  ⇒ globular proteins

-keratins  ⇒ fibrous proteins

-hemoglobin  ⇒ globular proteins

-water-soluble  ⇒ globular proteins

-collagens  ⇒ fibrous proteins

-insoluble in water  ⇒ fibrous proteins

-generally function in structure and support ⇒ fibrous proteins

Explanation:

<u>Fibrous proteins </u>are composed by large polypeptide chains which interact each other and form large structures. They have water insoluble and have structural and protection functions- they are components of cells and tissues. Examples are: collagen, fibronectin, keratin, elastin, actin.

<u>Globular proteins</u> have a spherical compact structure in which hydrophobic aminoacids are buried inside the structure and hydrophilic aminoacids (which can interact with water molecules) are exposed to the exterior medium. For this, they are water soluble. They have often transport and catalytic functions. For example: hemoglobin, mioglobin, albumin, enzymes in general.

Damm [24]

Answer:

Please find the explanation below

Explanation:

Virus is an organism that has been a topic of debate in biological sciences. This debate is based on whether virus should be classified as a living thing or not. However, it has been shown that viruses possess characteristics or properties of both living and non-living things.

The living thing characteristics include;

- Ability to reproduce or replicate (in living cells only and not on their own).

The nonliving characteristics include;

- Lack of cells, which is a strong criterion for every living thing in accordance to the universal cell theory.

- Inability to self-replicate i.e. reproduce on their own without a living host.
