The mineral is structured solid found in nature, with a fixed chemical composition. If a mineral scratches glass, the property hardness of the mineral is measured. The property hardness refers to the mineral's resistance to being scratched. In odrer to determine this property, scientists use the Moh's Hardness Scale. According this scale the mineral can be categorized as: <span>talc, gypsum, calcite, fluorite, apatite, orthoclase (feldspar), quartz, topaz, corundum or diamond.</span>

Your left wrist is what anatomical direction from your left elbow?
Norma-Jean [14]

Answer:

The correct answer will be- distal

Explanation:

In anatomy, the anatomist defined the standard position and movement of the bones of the skeletal system by universal anatomical terminologies.

The directional position of the bones of arms and legs is represented by the proximal and distal plane.

The proximal direction represents the bone closest to the point of origin or reference while distal represents the bone closest to the farthest away from the reference.  Since the left wrist is farther from the reference or the elbow therefore, it is considered distal to the elbow.

Thus, distal is the correct answer.

vfiekz [6]

Explanation:

The hypothesis states that the lizards living in different regions belong to the different food preferences.

No, the hypothesis will be proved correct only when the lizards will be kept in the same condition then their food preferences will be studied.

If their food preference will still be the same then it can be concluded that they reflect parental food preferences.

Else, if they will feed on the food given to them then the hypothesis will be rejected.

The sternal angleis the least likely part of A. the sternum to fracture in the elderly. B. occurs at the sternoclavicular joint.
Bumek [7]

Sternal angle marks the joint between the sternum and the 2nd rib.

Option E.

<h3><u>Explanation:</u></h3>

Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.

The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.
