Answer the following question given this paragraph: Cartilage Cartilage is a connective tissue with a large amount of the matrix and variable amounts of fibers. The cells, called chondrocytes, make the matrix and fibers of the tissue. Chondrocytes are found in spaces within the tissue called lacunae. A cartilage with few collagen and elastic fibers is hyaline cartilage, illustrated in Figure 33.14. The lacunae are randomly scattered throughout the tissue and the matrix takes on a milky or scrubbed appearance with routine histological stains. Sharks have cartilaginous skeletons, as does nearly the entire human skeleton during a specific pre-birth developmental stage. A remnant of this cartilage persists in the outer portion of the human nose. Hyaline cartilage is also found at the ends of long bones, reducing friction and cushioning the articulations of these bones. Q: Like sharks, nearly the entire human skeleton during a specific pre-birth developmental stage is made of what connective tissue? Choices: - chloroplasm - phloem - collagen - cartilage A:
cartilage

Q: What is transmitted that makes up the electromagnetic spectrum? Choices: - gamma rays - light waves of different wavelengths - sound waves of different frequencies - electromagnetic radiation in different wavelengths A:
A: electromagnetic radiation in different wavelengths
Question: Answer the following question given this paragraph: Protozoa that cause giardiasis are spread by contaminated food or water. They live inside the intestine. They may cause abdominal pain, fever, and diarrhea. Q: How are protozoa that cause giardiasis spread? Choices: - insects - starch and water - lakes and rivers - food and water A:
Answer: food and water

Answer the following question given this paragraph: Within the microsporangium, the microspore mother cell divides by meiosis to give rise to four microspores, each of which will ultimately form a pollen grain (Figure 32.7). An inner layer of cells, known as the tapetum, provides nutrition to the developing microspores and contributes key components to the pollen wall. Mature pollen grains contain two cells: a generative cell and a pollen tube cell. The generative cell is contained within the larger pollen tube cell. Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary. During its transit inside the pollen tube, the generative cell divides to form two male gametes (sperm cells). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther. Q: Within the microsporangium, the microspore mother cell divides by meiosis to give rise to four microspores, each of which will ultimately form this? Choices: - zygote - sperm cell - ova - pollen grain A:
**Answer**
pollen grain
