Answer the following question given this paragraph: DNA and RNA are nucleic acids. DNA stores genetic information. RNA helps build proteins. Proteins, in turn, determine the structure and function of all your cells. Proteins consist of chains of amino acids. A protein's structure and function depends on the sequence of its amino acids. Instructions for this sequence are encoded in DNA. Q: Both dna and rna are what type of acids? Choices: - proteins acids - synthesize acids - fatty acids - nucleic acids A:
nucleic acids
Answer the following question given this paragraph: In alpha decay, energy and an alpha particle are emitted by a nucleus that is unstable because it has too many protons. An alpha particle consists of two protons and two neutrons, so it is actually a helium nucleus. Q: What is an alpha particle with two protons and two neutrons called? Choices: - chloride nucleus - hydrogen nucleus - hydrogen nucleus - helium nucleus A:
helium nucleus
Q: Answer the following question given this paragraph: The three smallest alkanes are methane, ethane, and propane. Some hydrocarbons have one or more carboncarbon double bonds (denoted C=C). These hydrocarbons are called alkenes. http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gobch04_s06_f02shows the formulas and the molecular models of the two simplest alkenes. Note that the names of alkenes have the same stem as the alkane with the same number of carbon atoms in its chain but have the ending -ene. Thus, ethene is an alkene with two carbon atoms per molecule, and propene is a compound with three carbon atoms and one double bond. Figure 4.7 Formulas and Molecular Models of the Two Simplest Alkenes. Q: Methane, ethane, and propane are three of the smallest what? Choices: - organisms - atoms - microorganisms - alkanes A:
A: alkanes
Question: Answer the following question given this paragraph: A scientific law is a specific statement that is thought to be never violated by the entire natural universe. Everyday laws are arbitrary limits that society puts on its members. Q: What term describes a specific statement that is thought to be never violated by the entire natural universe? Choices: - evidence - hypothesis - theory - scientific law A:
Answer: scientific law

Answer the following question given this paragraph: Chapter 13 1 Figure 13.3 No. The predicted frequency of recombinant offspring ranges from 0% (for linked traits) to 50% (for unlinked traits). 3 Figure 13.6 B. 4 A 6 C 8 B 10 C 12 D 14 The Chromosomal Theory of Inheritance proposed that genes reside on chromosomes. The understanding that chromosomes are linear arrays of genes explained linkage, and crossing over explained recombination. Q: The chromosomal theory of inheritance proposed that what reside on chromosomes? Choices: - atoms - rna - molecules - genes A:
**Answer**
genes

Answer the following question given this paragraph: When we conserve resources, we also cut down on the trash we produce. Americans throw out 340 million tons of trash each year. We throw out 2.5 million plastic bottles aloneevery hour! Most of what we throw out ends up in landfills ( Figure below ). In a landfill, all those plastic bottles take hundreds of years to break down. What are the problems caused by producing so much trash? Natural resources must be used to produce the materials. Land must be given over to dump the materials. If the materials are toxic, they may cause pollution. Q: What is another environmental benefit of conserving resources? Choices: - more jobs - warmer temperatures - lower prices - less trash A:
**Answer**
less trash
