<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
Explanation:
Tarbuck, Earth's crust is made up of several elements: oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent
About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which all together constitute the hydrosphere.

Earth.
Almost 99% of the minerals making up the Earth's crust are made up of just eight elements. Most of these elements are found combined with other elements as compounds.
Answer: Starch did not diffuse through the membrane because the starch turned blue due to the presence of iodine in the dialysis bag
Explanation:
A smaller person would have a lower metabolism rate than a taller person.
Answer: Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.
Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
