Answer the following question given this paragraph: Metals are elements that can conduct electricity. They are one of three classes of elements (the other two classes are nonmetals and metalloids). Metals are by far the largest of the three classes. In fact, most elements are metals. All of the elements on the left side and in the middle of the periodic table, except for hydrogen, are metals. There are several different types of metals, including alkali metals in group 1 of the periodic table, alkaline Earth metals in group 2, and transition metals in groups 312. The majority of metals are transition metals. Q: The three classes of elements are metals, nonmetals, and what? Choices: - ionic compounds - molecules - atoms - metalloids A:
metalloids
Answer the following question given this paragraph: The rate of decay of a radioactive substance is constant over time. Q: What remains a constant of radioactive substance over time? Choices: - temperature - volatility - acidity - rate of decay A:
rate of decay
Q: Answer the following question given this paragraph: Ribosomes are the organelles on which proteins are made during protein synthesis . Ribosomes are found throughout the cytosol of the cell and attached to the endoplasmic reticulum organelle. Ribosomes order amino acids using messenger RNA (mRNA) as a template in a process called translation. Ribosomes are made from complexes of ribosomal RNAs (rRNA) and proteins called ribonucleoproteins . Each ribosome is divided into two subunits. The smaller subunit binds to the mRNA pattern, while the larger subunit binds to the transfer RNA (tRNA) and the growing polypeptide chain. More about the ribosome will be discussed in the Cell Structures: Ribosomes (Advanced) concept. Q: What are the organelles on which proteins are made during protein synthesis called? Choices: - mitochondria - lysosomes - fibroblasts - ribosomes A:
A: ribosomes
Question: Answer the following question given this paragraph: The spin quantum number describes the spin for a given electron. An electron can have one of two associated spins, spin, or spin. An electron cannot have zero spin. We also represent spin with arrows or . A single orbital can hold a maximum of two electrons and each must have opposite spin. Q: The spin quantum number describes the spin for a given what? Choices: - ion - element - proton - electron A:
Answer: electron

Answer the following question given this paragraph: Another mechanism besides diffusion to passively transport materials between compartments is filtration. Unlike diffusion of a substance from where it is more concentrated to less concentrated, filtration uses a hydrostatic pressure gradient that pushes the fluidand the solutes within itfrom a higher pressure area to a lower pressure area. Filtration is an extremely important process in the body. For example, the circulatory system uses filtration to move plasma and substances across the. Q: What is used during filtration to push fluids and solutes, from higher pressure areas to lower pressure areas? Choices: - constructs pressure gradient - limited pressure gradient - magnesium pressure gradient - hydrostatic pressure gradient A:
**Answer**
hydrostatic pressure gradient
