Answer:

As explained below.

Explanation:

  • The rocks can be identified by the three types of igneous, sedimentary and metamorphic types. Most of the rocks sedimentary rocks have mineral streak streams. Thus a steak test is done by scraping the base of the rock and hence finding out the amount if powdered mineral on the surface of the rocks.
  • The red color can be attributed to the Aztec sandstones which has such type f structure, due to the presence of iron oxide or hematite and the exposure to other minerals may cause the rocks to rust or change their form and brown color.
  • Pyrite is one of the most commonly found earth minerals everywhere on the earth in the form of a yellow stretch.

Which part of the nervous system is outside the brain and spinal cord?
Elis [28]

Answer:

The correct answer is: the peripheral nervous system.

Explanation:

The Peripheral Nervous System (PNS) is one of the two anatomical divisions of the nervous system. The PNS is composed of nerves and ganglia that are outside of the brain and spinal cord.

The function of the PNS is to <u>transmit the information from the body to the Central Nervous System and vice-versa</u>.

Unlike the CNS, the PNS is <u>not protected by bones</u> so it's much more exposed to mechanical injuries.

What type of amino acids would you expect to find at the core of a water-soluble globular (solid-spherical) protein
PIT_PIT [208]

Hydrophobic amino acids are buried at the core of a water-soluble globular protein.

<h3>What makes globular proteins water soluble?</h3>

Numerous hundreds to thousands of amino acids are used to make proteins. The arrangement of amino acids within a protein molecule determines its ultimate form. A protein molecule is classified into two classes—fibrous proteins and globular proteins—based on its final shape.

The structure of globular proteins resembles a ball or a globe. A globular structure is created by the folding of different amino acid chains. The two most significant globular proteins present in the human body are hemoglobin and myoglobin. The hydrophobic side chains of the amino acids are hidden inside the cores of the domains whereas the hydrophilic side chains are located on the surface of the molecule thanks to the arrangement of the amino acids.

The hydrophobic amino acids can be buried in the center of globular proteins due to interactions between the hydrophobic groups in their side chains. This is the fundamental property of globular proteins that makes them water soluble.

Examples of hydrophobic amino acids are phenylalanine,  alanine, valine, etc.
