Answer the following question given this paragraph: Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus and many other organelles. All of these cell parts must be duplicated and then separated when the cell divides. Q: What type of cell has a singular chromosome, no nucleus, and few other organelles? Choices: - trophic - graphic - monophyletic - prokaryotic A:
prokaryotic

Answer the following question given this paragraph: The increase in electrons across the periodic table explains why elements go from metals to metalloids and then to nonmetals from left to right across the table. Look at period 2 in Figure below as an example. Lithium (Li) is a metal, boron (B) a metalloid, and fluorine (F) and neon (Ne) are nonmetals. The inner energy level is full for all four elements. This level has just one orbital and can hold a maximum of two electrons. The outer energy level is a different story. This level has four orbitals and can hold a maximum of eight electrons. Lithium has just one electron in this level, boron has three, fluorine has seven, and neon has eight. Q: An increase in what, across the periodic table, explains why elements go from metals to metalloids and then to nonmetals? Choices: - neutrons - temperature - protons - electrons A:
(Answer)
electrons
Ques: Answer the following question given this paragraph: The enormous number of species is due to the tremendous variety of environments in which they can live. Q: The enormous number of species is due to the tremendous variety of what? Choices: - tissues - sounds - measurements - environments A:
Ans: environments

Answer the following question given this paragraph: Renewable resources are natural resources that are remade by natural processes as quickly as people use them. Examples of renewable resources include sunlight and wind. They are in no danger of being used up. Metals and some other minerals are considered renewable as well because they are not destroyed when they are used. Instead, they can be recycled and used over and over again. Q: What do we call natural resources that are remade by natural processes as quickly as people use them? Choices: - nonrenewable - exotic - geothermal - renewable A:
(A).
renewable
Ques:Answer the following question given this paragraph: Q: But a point mutation can also change a codon for an amino acid into a what? Choices: - axon - exon - stop mutation - stop codon A:

Ans:stop codon
Ques: Answer the following question given this paragraph: Several substances HCl, NH 3 , and SO 2 have solubility that decreases as temperature increases. They are all gases at standard pressure. When a solvent with a gas dissolved in it is heated, the kinetic energy of both the solvent and solute increases. As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases. Q: When a solvent with a gas dissolved in it is heated, the kinetic energy of both the solvent and solute _________? Choices: - evaporates - generates - decreases - increases A:
Ans:
increases
