Answer the following question given this paragraph: This phylogenetic tree is based on comparisons of ribosomal RNA base sequences among living organisms. The tree divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Humans and other animals belong to the Eukarya domain. From this tree, organisms that make up the domain Eukarya appear to have shared a more recent common ancestor with Archaea than Bacteria. Q: What will spores that eventually germinate develop into? Choices: - yeast cells - gametes - hydra - new hyphae A:
new hyphae

Answer the following question given this paragraph: Silver and ordinary table salt are two examples of chemical substances . A substance is matter that has a uniform and definite composition. All samples of substances, sometimes called pure substances, have identical properties. When chemists run a chemical reaction, they want to use pure materials so they know exactly what they are dealing with. They know that the reaction involves a specific substance, so they expect the same reaction to give the same results each time it is run. Q: Silver and ordinary table salt are two examples of chemical what? Choices: - organism - impurities - microbes - substances A:
(Answer)
substances
Ques: Answer the following question given this paragraph: The disintegration of unstable nuclei does not occur all at once. The rate of disintegration is a statistical process. The most convenient way to consider it is by a concept known as half-life . The time required for half of the atoms in any given quantity of a radioactive substance to decay is the half-life of that element. Each particular isotope has its own half-life. For example, the half-life of radium-226 is 1600 years. That is, beginning with 1.00 gram of radium-226, it would take 1600 years for half of it to decay and leave 0.50 gram remaining. After another 1600 years, only 0.25 gram would remain. In each half-life, exactly half of the beginning amount decays. Q: What is the time it takes for radioactive substance to decay? Choices: - decay rate - full-life - deterioration rate - half-life A:
Ans: half-life

Ques:Answer the following question given this paragraph: Bones become increasingly ossified and grow larger during fetal development, childhood, and adolescence. When skeletal maturity is reached at about age 20, no additional growth in bone length can occur. Q: At what age is skeletal maturity reached by humans? Choices: - 40 - 30 - 15 - 20 A:

Ans:20
