Answer - Hardness
Reason - Given the moths scale you can determined the resistance.
<span>The physical characteristics of minerals include traits which are used to identify and describe mineral species. These traits include color, streak, luster, density, hardness, cleavage, fracture, tenacity, and crystal habit.</span>
The first can be filled with an element and the second blank can be filled with a compound.
Iron is an element as it contains only one kind of atom, which combines with the oxygen from the air to produce rust, that is, iron oxide. The rust comprises two kinds of atoms, which signifies that it is a compound. A compound refers to a molecule that comprises at least two types of atoms. In the case, iron oxide is a compound as it comprises Fe and O atom.
All of the following activities occur in the course of prophase in mitosis except crossing over.
Mitosis may be divided into 4 stages: prophase, metaphase, anaphase, and telophase.
Throughout prophase, the chromatids condense into chromosomes, thereby making them seen. The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This shape is formed in prophase.
In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the mobile, and sister chromatids are connected to the spindle fiber.
Crossing over (or recombination) is the alternate of genetic cloth between non-sister chromatids that occurs in the course of prophase I of meiosis.
In end, condensation of DNA, the pairing of chromosomes, and, spindle formation arise for the duration of prophase, while crossing over occurs in prophase I of the meiotic cellular department (choice B).
