Answer the following question given this paragraph: You have learned that an allele is an alternative form of a gene. Most, if not all genes have alternative forms causing the resulting protein to function slightly differently. But are there alleles that cause proteins to function dramatically differently or not function at all? A mutation is a change in the DNA or RNA sequence, and many mutations result in new alleles. Some mutations have no effect on the protein, whereas others are either beneficial or harmful. In fact, evolution could not take place without the genetic variation that results from beneficial mutations. In humans, harmful mutations can result in genetic diseases. There are also chromosomal mutations, large changes with dramatic effects. See Mutations are changes in genetic information at http://www. dnaftb. org/27/animation. html for a description of the early work on mutations. Q: An allele is an alternative form of what structure? Choices: - amino acid - enzyme - protein - gene A:
gene
Answer the following question given this paragraph: Cells are the basic building blocks of life. They are like tiny factories where virtually all life processes take place. Some living things, like the bacteria in Figure above , consist of just one cell. They are called single-celled organisms. You can see other single-celled organisms in Figure 2.2. Some living things are composed of a few to many trillions of cells. They are called multicellular organisms. Your body is composed of trillions of cells. Q: What do we consider the basic building blocks of life? Choices: - atoms - neurons - muscles - cells A:
cells
Q: Answer the following question given this paragraph: Both temperature and pressure have an effect on the phase in which a given substance exists. A plot of temperature vs. pressure that indicates the states of matter present at each point is known as a phase diagram . Figure below shows the phase diagram for water. Q: A phase diagram plots temperature and what else? Choices: - friction - power - movement - pressure A:
A: pressure
Question: Answer the following question given this paragraph: Heat is the transfer of thermal energy between substances. Thermal energy is the kinetic energy of moving particles of matter, measured by their temperature. Thermal energy always moves from matter with greater thermal energy to matter with less thermal energy, so it moves from warmer to cooler substances. You can see this in the Figure below . Faster-moving particles of the warmer substance bump into and transfer some of their energy to slower-moving particles of the cooler substance. Thermal energy is transferred in this way until both substances have the same thermal energy and temperature. For a visual introduction to these concepts, watch the animation "Temperature vs. Heat" at this URL:. Q: Kinetic energy of moving particles of matter, measured by their temperatures are known as: Choices: - visible energy - atmospheric energy - solar energy - thermal energy A:
Answer: thermal energy

Answer the following question given this paragraph: The Hubble space telescope shows that technology and science are closely related. Technology uses science to solve problems, and science uses technology to make new discoveries. However, technology and science have different goals. The goal of science is to answer questions and increase knowledge. The goal of technology is to find solutions to practical problems. Although they have different goals, science and technology work hand in hand, and each helps the other advance. Scientific knowledge is used to create new technologies such as the space telescope. New technologies often allow scientists to explore nature in new ways. Q: What is the goal of science? Choices: - improve knowledge - improve life expectancy - gain scholarships - increase knowledge A:
**Answer**
increase knowledge
Answer the following question given this paragraph: Q: In flowering plants, male gametophytes are in grains of what? Choices: - viruses - bacteria - nitrogen - pollen A:
pollen
