Q: Answer the following question given this paragraph: Chemical weathering is different than mechanical weathering. The minerals in the rock change. The rock changes composition and becomes a different type of rock. Most minerals form at high pressure or high temperatures deep within Earth. But at Earth's surface, temperatures and pressures are much lower. Minerals that were stable deeper in the crust are not stable at the surface. That's why chemical weathering happens. Minerals that formed at higher temperature and pressure change into minerals that are stable at the surface. Chemical weathering is important. It starts the process of changing solid rock into soil. We need soil to grow food and create other materials we need. Chemical weathering works through chemical reactions that change the rock. Q: What type of weathering causes the minerals in a rock to change? A:
Answer: chemical

Problem:OPTIONS:
- neutrality
- hydrogeny
- oxidation
- ph

Answer the following question given this paragraph: Acidity is measured by pH, which is the concentration of hydrogen ions in a solution. Q: What is described by the concentration of hydrogen ions in a solution? A:
****
A: ph

Answer the following question given this paragraph: The cell is the basic unit of structure and function of all organisms. The Cell Theory states that all living things are made of one or more cells, or the secretions of those cells, such as the organisms shown in Figure below . For example, shell and bone are built by cells from substances that they secrete into their surroundings. Cells come from cells that already exist, that is, they do not suddenly appear from nowhere. In organisms that are made of many cells (called multicellular organisms), every cell in the organism's body derives from the single cell that results from a fertilized egg. You will learn more about cells and the Cell Theory in Cells: The Cell Theory (Advanced) concept. Q: What is the basic unit of structure and function in all organisms? A:
OPTIONS:
- the atom
- the neutron
- the electron
- the cell
the cell

Answer the following question given this paragraph: Introduction All living organisms need nutrients to survive. While plants can obtain the molecules required for cellular function through the process of photosynthesis, most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular functions, such as assembling new molecules, cells, and tissues. The conversion of the food consumed to the nutrients required is a multi-step process involving digestion and absorption. During digestion, food particles are broken down to smaller components, and later, they are absorbed by the body. Q: Plants obtain the molecules for cellular function though what? A:
OPTIONS:
- tissues
- nutrients
- Plants
- photosynthesis

Answer: photosynthesis
