Q: What is the term for the class of ectothermic, four-legged vertebrates that produce amniotic eggs? Read this paragraph and choose the correct option from the provided answers: Reptiles are a class of ectothermic, four-legged vertebrates that produce amniotic eggs. They include turtles, crocodiles, lizards, and snakes. Reptiles were the first vertebrates to live full time on land, and they evolved many terrestrial adaptations. Choices: - mammals - Turtles - amphibians - reptiles A:
reptiles

Q: The radial artery and which artery parallel their namesake bones, giving off smaller branches until they reach the wrist, or carpal region? Read this paragraph and choose the correct option from the provided answers: Arteries Serving the Upper Limbs As the subclavian artery exits the thorax into the axillary region, it is renamed the axillary artery. Although it does branch and supply blood to the region near the head of the humerus (via the humeral circumflex arteries), the majority of the vessel continues into the upper arm, or brachium, and becomes the brachial artery (Figure 20.31). The brachial artery supplies blood to much of the brachial region and divides at the elbow into several smaller branches, including the deep brachial arteries, which provide blood to the posterior surface of the arm, and the ulnar collateral arteries, which supply blood to the region of the elbow. As the brachial artery approaches the coronoid fossa, it bifurcates into the radial and ulnar arteries, which continue into the forearm, or antebrachium. The radial artery and ulnar artery parallel their namesake bones, giving off smaller branches until they reach the wrist, or carpal region. At this level, they fuse to form the superficial and deep palmar arches that supply blood to the hand, as well as the digital arteries that supply blood to the digits. Figure 20.32 shows the distribution of systemic arteries from the heart into the upper limb. Table 20.9 summarizes the arteries serving the upper limbs. Choices: - triceps - humerus - biceps - ulnar A:
ulnar

Q: Asexual reproduction occurs by what process? Read this paragraph and choose the correct option from the provided answers: Sponges reproduce both asexually and sexually. Asexual reproduction occurs by budding. Figure below shows the sponge life cycle when sexual reproduction is involved. Adult sponges produce eggs and sperm. In many species, the same individuals produce both. However, they don't produce eggs and sperm at the same time. As a result, self-fertilization is unlikely to occur. What is an advantage of avoiding self-fertilization?. Choices: - mating - balancing - ripening - budding A:
budding
