7 0

Answer: This is a hard question because we need copper for just about anything. Some people say that electric cars are better because the conserve fuel, but they have copper. The source of all of our power (electricity) stems from copper. Simply said, no matter what you do to conserve copper, you are still going to need it and use it.

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.

Describe what happens to the air in the lungs when we breathe. What happens to the concentration of

Otrada [13]

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Hope this helped, even if it helped a tiny bit. :)

How are some fish specially adapted to attract prey or to escape predators?

Mariana [72]

Fish have adaptable behaviors and structures so that they can survive in the wild. These adaptations however differ with regards to context and environment. Some fishes for example are called stonefish because they can camouflage in environments that are composed variedly with pebbles and rocks, and this helps them to avoid predators and thrive. Nevertheless, when these group of organisms are strayed and become exposed to a new environment they can be exposed and be vulnerable to predators.
