Answer the following question given this paragraph: Insects generally have two pairs of wings for flight. Wings are part of the exoskeleton and attached to the thorax. Insect wings show a lot of variation. As you can see in Figure below , butterfly wings are paper-thin, whereas beetle wings are like armor. Not all insect wings work the same way, either. They differ in how the muscles are attached and whether the two pairs of wings work independently or together. Besides flight, wings serve other functions. They may protect the body (beetles), communicate visually with other insects (butterflies), or produce sounds to attract mates (katydids). Q: Insect wings are part of the exoskeleton and attached to the what? Choices: - neck - head - spines - thorax A:
thorax
Answer the following question given this paragraph: Radar stands for ra dio d etection and r anging. In police radar, a radar gun sends out short bursts of microwaves. The microwaves reflect back from oncoming vehicles and are detected by a receiver in the radar gun. The frequency of the reflected waves is used to compute the speed of the vehicles. Radar is also used for tracking storms, detecting air traffic, and other purposes. Q: In police radar, a radar gun sends out short bursts of which waves? Choices: - photons - soundwaves - electrodes - microwaves A:
microwaves
Q: Answer the following question given this paragraph: Are there male and female bacteria? How could you tell? Remember, bacteria have just one chromosome; they do not have an X or Y chromosome. So they probably have a very simplified form of reproduction. Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone , an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation. All prokaryotic and some eukaryotic organisms reproduce asexually. Q: All prokaryotic and some eukaryotic organisms reproduce through what method, where a parent passes all of its genetic material to the next generation? Choices: - organic reproduction - sexual reproduction - microscopic reproduction - asexual reproduction A:
A: asexual reproduction
Question: Answer the following question given this paragraph: Water is a compound that consists of the elements hydrogen (H) and oxygen (O). Like other compounds, the smallest particles of water are called molecules. Each molecule of water (H 2 O) contains two atoms of hydrogen and one atom of oxygen. Q: What are the smallest particles of water called? Choices: - hydrogen - atoms - ions - molecules A:
Answer: molecules

Answer the following question given this paragraph: Genetics is the study of inheritance. Inheritance is the passing of traits from parents to offspring. How are these traits "passed"? Through DNA, which is the genetic material of all organisms. This concept will focus on genetics, inheritance, and DNA. Q: The passing of traits from parents to offspring is done through what? Choices: - sperm - egg - blood - dna A:
**Answer**
dna

Answer the following question given this paragraph: The number of waves that pass a fixed point in a given amount of time is wave frequency . Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves. The SI unit for wave frequency is the hertz (Hz) , where 1 hertz equals 1 wave passing a fixed point in 1 second. The Figure below shows high-frequency and low-frequency transverse waves. You can simulate transverse waves with different frequencies at these URLs: http://phet. colorado. edu/en/simulation/wave-on-a-string and http://zonalandeducation. com/mstm/physics/waves/partsOfAWave/waveParts. htm. Q: What are waves that pass a fixed point in a given amount of time called? Choices: - tendency frequency - combination frequency - radio frequency - wave frequency A:
(A).
