Minerals are solid, inorganic substances that

a. exist naturally

b. are manufactured

c. are found exclusively on earth

d. are made of iron

Answer;

A. exist naturally

Minerals are solid, inorganic substances that exist naturally.

Explanation;

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.

Minerals are naturally occurring; they are not made by humans.

Minerals are inorganic; they have never been alive and are not made up from plants or animals.

Minerals are solids; they are not liquids (like water), or gases (like the air around you).

Minerals have a definite chemical composition; each one is made of a particular mix of chemical elements.

Minerals have an ordered atomic arrangement; the chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
