Answer the following question given this paragraph: Summary The periodic table is an arrangement of the elements in order of increasing atomic number. Elements that exhibit similar chemistry appear in vertical columns calledgroups (numbered 118 from left to right); the seven horizontal rows are calledperiods. Some of the groups have widely used common names, including thealkali metals (group 1) and the alkaline earth metals (group 2) on the far left, and the halogens (group 17) and the noble gases (group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals. Semimetals exhibit properties intermediate between those of metals and nonmetals. Metals are located on the left of the periodic table, and nonmetals are located on the upper right. They are separated by a diagonal band of semimetals. Metals are lustrous, good conductors of electricity, and readily shaped (they areductile and malleable), whereas solid nonmetals are generally brittle and poor electrical conductors. Other important groupings of elements in the periodic table are the main group elements, the transition metals, the lanthanides, and the actinides. Q: The periodic table is an arrangement of the elements in order of increasing what? Choices: - gravity numbers - metallic numbers - negative numbers - atomic numbers A:
(A).
atomic numbers
Ques:Answer the following question given this paragraph: Passive transport occurs when a substance passes through the cell membrane without needing any energy to pass through. This happens when a substance moves from an area where it is more concentrated to an area where it is less concentrated. Concentration is the number of particles of a substance in a given volume. Let's say you dissolve a teaspoon of salt in a cup of water. Then you dissolve two teaspoons of salt in another cup of water. The second solution will have a higher concentration of salt. Q: When substances pass through the cell membrane without needing any energy what is it called? Choices: - active transport - kinetic transport - energetic transport - passive transport A:

Ans:passive transport
Ques:Answer the following question given this paragraph: Many species use their body shape and coloration to avoid being detected by predators. The tropical walking stick is an insect with the coloration and body shape of a twig which makes it very hard to see when stationary against a background of real twigs (Figure 45.20a). In another example, the chameleon can change its color to match its surroundings (Figure 45.20b). Both of these are examples of camouflage, or avoiding detection by blending in with the background. Q: Many species use their body shape and coloration to avoid what? Choices: - exposure - sunlight - human contact - detection by predators A:

Ans:
detection by predators
