1. horizontal

2. vertical

3. inclined

Explanation:

         The strata are defined as the layers of various rocks. It may be sedimentary rocks, igneous rocks, etc. The orientation of the strata determines the position of the rock layers or the altitude of the rocks in the three dimensional spaces in the earth's crust.

In the context,

           The outcrop pattern of the horizontal strata are cut by the stream canyons that are parallel to the canyon walls. And the outcrop pattern of the vertical strata are cut by the stream canyon that makes an apparent straight line that crosses the canyon.

           While the pattern of the inclined strata that are cut by the stream canyon which makes the apparent V shape and is pointing in dip direction.

          This is because as per the rules of the V's, the inclined beds or the dipping are incised with the streams or valleys or canyons, it makes a "V" in dip direction. But when the strata have a vertical dip, then it does not make a "V". And when the beds are horizontal, it will be parallel and will follow the contours.

Each specific property of motif and domain is explained.

Explanation:

Domain;

May retain a 3D structure when separated from rest of the protein.           Unit of tertiary structure because alpha helix and beta sheets are units of secondary structure.Stable globular units like pyruvate kinaseMay be distinct functional units in a protein

Motif;

Repetetive supersecondary structure because they contain cluster of secondary structure.Beta Alpha Beta unit is an example of motifClusters of secondary structure

Both Motif and Domain;

Stabilized by hydrophobic interactions like hydrogen bonding stabilize the both.Depends on primary structure like the arrangement of amino acid in polypeptide chain determine the secondary and tertiary structure of proteins.

Explanation:

hi there

your answer to this response is

Proteins are the most versatile macro molecules in living systems and serve crucial functions in essentially all biological processes. The proteins they  fold up into three dimensional structures that are determined by the sequence of amino acids in the protein polymer.

i hope this helps you out

i have a great morning

Explanation:

also, is this like a sample answer because this is really good

Our understanding of life at the molecular level is highly dependent on the ability to map the molecular details of individual proteins and nucleic acids as well as their interactions with each other and with small molecules (inhibitors, cofactors, substrates, etc.). The determination of 3-D structures of proteins is crucial for the understanding of these interactions as well as their structure–function relationships, which also has many practical applications in drug design and protein engineering.

See below

Explanation:

Potassium channels have the ability to allow only potassium ions to pass through with a remarkable accuracy. This is achieved due to the presence of a selectivity filter. There are 8 molecules of water that surround this filter. If the K+ ion is to go through the filter, it will have to lose these molecules. The dimensions of this pore, as determined by its 3D structure, correspond only to the K+ ions and not Na+ ions which are smaller in size and thus, will not be able to pass through the filter.

See explanation and image attached

Explanation:

Often times, there is a need for a three dimensional representation of a molecule on paper. These three dimensional representations give us an idea of what the molecule really looks like if we were to be looking at it physically.

In order to make a three dimensional representation, we use wedged and dashed bonds. The wedged bonds are coming out of the plane of the paper towards you while the dashed bonds are going into the plane of the paper away from you.

In the image attached, you will find the three dimensional representation of the methane molecule.
