Answer the following question given this paragraph: Plant Life Spans The length of time from the beginning of development to the death of a plant is called its life span. The life cycle, on the other hand, is the sequence of stages a plant goes through from seed germination to seed production of the mature plant. Some plants, such as annuals, only need a few weeks to grow, produce seeds and die. Other plants, such as the bristlecone pine, live for thousands of years. Some bristlecone pines have a documented age of 4,500 years Figure 32.29. Even as some parts of a plant, such as regions containing meristematic tissuethe area of active plant growth consisting of undifferentiated cells capable of cell divisioncontinue to grow, some parts undergo programmed cell death (apoptosis). The cork found on stems, and the water-conducting tissue of the xylem, for example, are composed of dead cells. Q: Life span is distinct from what, which means the sequence of stages a plant goes through from seed germination to seed production of the mature plant? Choices: - feeding cycle - society cycle - spin cycle - life cycle A:
life cycle
Answer the following question given this paragraph: Imagine trying to slice a tomato with a fork or spoon instead of a knife, like the one in Figure below . The knife makes the job a lot easier because of the wedge shape of the blade. A wedge is a simple machine that consists of two inclined planes. But unlike one inclined plane, a wedge works only when it moves. It has a thin end and thick end, and the thin end is forced into an object to cut or split it. The chisel in Figure below is another example of a wedge. Q: What is the name for a simple machine that consists of two inclined planes? Choices: - slope - pulley - lever - wedge A:
wedge
Q: Answer the following question given this paragraph: Bacterial infections of the urinary tract, especially the bladder, are very common. Bladder infections can be treated with antibiotics prescribed by a doctor. If untreated, they may lead to kidney damage. Q: Which organ will bladder infections commonly damage if untreated? Choices: - lungs - heart - tissue - kidney A:
A: kidney
Question: Answer the following question given this paragraph: Do you see the man sitting on top of this tanker truck? He gives you a sense of how big the truck is. What's behind the truck? Is it a huge apartment complex? It's just as massive as a very large building, but it's not even resting on land. It's a giant cruise ship, and it's floating on water. The ship weighs about 100,000 metric tons. How can such a tremendous weight float on water? Why doesn't it sink to the bottom of the ocean instead? Archimedes' law explains why. Q: Which law explains why a ship weighing thousands of metric tons floats on water? Choices: - hofstadter ' law - ganymede ' law - water pressure law - archimedes' law A:
Answer: archimedes' law

Q: What property of toluene and xylene makes them important in the chemical industry? Choices: - excess property - corrosive property - isolate property - solvent property A:
**Answer**
solvent property
Answer the following question given this paragraph: Genes that are located on the same chromosome are called linked genes . Alleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-over occurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over. At the following link, you can watch an animation showing how genes on the same chromosome may be separated by crossing-over: http://www. biostudio. com/d_%20Meiotic%20Recombination%20Between%20Linked%20Genes. htm . Q: Linked genes are located on the same what? Choices: - genome - nucleolus - bacterium - chromosome A:
chromosome
