Answer the following question given this paragraph: Figure 42.1 In this compound light micrograph purple-stained neutrophil (upper left) and eosinophil (lower right) are white blood cells that float among red blood cells in this blood smear. Neutrophils provide an early, rapid, and nonspecific defense against invading pathogens. Eosinophils play a variety of roles in the immune response. Red blood cells are about 78 m in diameter, and a neutrophil is about 1012m. (credit: modification of work by Dr. David Csaba). Q: What provides an early, rapid, and nonspecific defense against invading pathogens? Choices: - microorganisms - toxins - bacteria - neutrophils A:
neutrophils
Answer the following question given this paragraph: The main reason that insects have been so successful is their ability to fly. Insects are the only invertebrates that can fly and the first animals to evolve flight. Flight has important advantages. It's a guaranteed means of escape from nonflying predators. It also aids in the search for food and mates. Q: What are the only invertebrates that can fly? Choices: - birds - amphibians - mammels - insects A:
insects
Q: Answer the following question given this paragraph: During mitosis, the newly duplicated chromosomes are divided into two daughter nuclei. Q: Newly duplicated chromosomes are divided into two daughter nuclei during what stage? Choices: - meiosis - symphysis - prophase - mitosis A:
A: mitosis
Question: Answer the following question given this paragraph: All plants have a characteristic life cycle that includes alternation of generations . Plants alternate between haploid and diploid generations. Alternation of generations allows for both asexual and sexual reproduction. Asexual reproduction with spores produces haploid individuals called gametophytes . Sexual reproduction with gametes and fertilization produces diploid individuals called sporophytes . A typical plant's life cycle is diagrammed in Figure below . Q: The plants alternation between haploid and diploud generations allow it to do what? Choices: - reproduce asexually and simultaneously - reproduce sexually and autonomously - reproduce asexually and biologically - reproduce asexually and sexually A:
Answer: reproduce asexually and sexually
*Question*
Answer the following question given this paragraph: Q: What helps to convert some molecules to forms that can be taken up by other organisms? Choices: - eukaryotes - protists - scavangers - prokaryotes A:
**Answer**
prokaryotes
Q: Answer the following question given this paragraph: Electromagnetic radiation is energy that travels in waves across space as well as through matter. Most of the electromagnetic radiation on Earth comes from the sun. Like other waves, electromagnetic waves are characterized by certain wavelengths and wave frequencies. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. Electromagnetic waves with shorter wavelengths have higher frequencies and more energy. Q: What type of energy travels in waves across space as well as through matter? Choices: - kinetic energy - mechanical radiation - thermal energy - electromagnetic radiation A:
A: electromagnetic radiation
