Proteins may be classified according to their three-dimensional shapes. Determine whether the following examples and description

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:

Fibrous proteins 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.

Globular proteins 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.

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups

vitfil [10]

Answer:

geographical isolation

Explanation:

Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.

There are two mechanisms of reproductive isolation:

Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.

Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.
