Answer the following question given this paragraph: 9.6 | Anatomy of Selected Synovial Joints By the end of this section, you will be able to: Describe the bones that articulate together to form selected synovial joints Discuss the movements available at each joint Describe the structures that support and prevent excess movements at each joint Each synovial joint of the body is specialized to perform certain movements. The movements that are allowed are determined by the structural classification for each joint. For example, a multiaxial ball-and-socket joint has much more mobility than a uniaxial hinge joint. However, the ligaments and muscles that support a joint may place restrictions on the total range of motion available. Thus, the ball-and-socket joint of the shoulder has little in the way of ligament support, which gives the shoulder a very large range of motion. In contrast, movements at the hip joint are restricted by strong ligaments, which reduce its range of motion but confer stability during standing and weight bearing. This section will examine the anatomy of selected synovial joints of the body. Anatomical names for most joints are derived from the names of the bones that articulate at that joint, although some joints, such as the elbow, hip, and knee joints are exceptions to this general naming scheme. Q: A multiaxial ball-and-socket joint has much more mobility than a what hinge joint? Choices: - triaxial - biaxial - quadaxial - uniaxial A:
uniaxial

Answer the following question given this paragraph: The first and longest phase of mitosis is prophase . During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figure below , consists of fibers made of microtubules. Q: Chromatin condenses into chromosomes during prophase, the first and longest phase of what process? Choices: - reproduction - apoptosis - meiosis - mitosis A:
(Answer)
mitosis
Ques: Answer the following question given this paragraph: Amphibians are an important food source for animals such as birds, snakes, raccoons, and fish. Amphibians are also important predators. As larvae, they feed mainly on small aquatic animals such as water insects. They may also feed on algae. As adults, amphibians are completely carnivorous . They may catch and eat worms, snails, and insects, as the frog in Figure below is doing. Unlike other amphibians, caecilians are burrowers . They use their head to dig in the soil, and they feed on earthworms and other annelids. Caecilians can be found in moist soil near rivers and streams in tropical regions. Q: As adults, amphibians are completely _______, meaning they feed on other animals. Choices: - herbivorous - monogamous - omnivorous - carnivorous A:
Ans: carnivorous
(Q).
Answer the following question given this paragraph: Today, fungi are no longer classified as plants. We now know that they have unique physical, chemical, and genetic traits that set them apart from plants and other eukaryotes. For example, the cell walls of fungi are made of chitin , not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food. These are just a few of the reasons fungi are now placed in their own kingdom. Q: Fungi are no longer classified as what, possessing cell walls made of chitin rather than cellulose? Choices: - roots - eukaryotes - flowers - plants A:
(A).
plants
Ques:Answer the following question given this paragraph: diploid spore in fungi that is produced by the fusion of two haploid parent cells. Q: Caffeine is an example of what type of drug? Choices: - depressant - barbiturate - nicotine - psychoactive A:

Ans:psychoactive
Ques:Answer the following question given this paragraph: Most invertebrates reproduce sexually. Diploid adults produce haploid gametes (sperm and eggs). In some species, the same individuals produce both sperm and eggs. In other species, sperm and eggs are produced by separate male and female individuals. Fertilization occurs when a sperm and an egg fuse to form a diploid zygote. The zygote develops into an embryo and eventually into a new adult organism. On the way, it may pass through one or more larval stages. A larva (plural, larvae) is a juvenile, or immature, stage of an animal. It is generally quite different in form and function from the adult form of the species. For example, the larva may be able to swim freely, whereas the adult must remain permanently attached to a solid surface. Q: How do invertebrates reproduce? Choices: - randomly - constantly - asexually - sexually A:

Ans:
sexually
