Answer the following question given this paragraph: 27.1 | Features of the Animal Kingdom By the end of this section, you will be able to: List the features that distinguish the kingdom Animalia from other kingdoms Explain the processes of animal reproduction and embryonic development Describe the roles that Hox genes play in development Even though members of the animal kingdom are incredibly diverse, most animals share certain features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have a complex tissue structure with differentiated and specialized tissues. Most animals are motile, at least during certain life stages. All animals require a source of food and are therefore heterotrophic, ingesting other living or dead organisms; this feature distinguishes them from autotrophic organisms, such as most plants, which synthesize their own nutrients through photosynthesis. As heterotrophs, animals may be carnivores, herbivores, omnivores, or parasites (Figure 27.2ab). Most animals reproduce sexually, and the offspring pass through a series of developmental stages that establish a determined and fixed body plan. The body plan refers to the morphology of an animal, determined by developmental cues. Q: Because all animals require an external source of what, they are called heterotrophic? Choices: - fuel - energy - water - food A:
(Answer)
food
Ques: Answer the following question given this paragraph: In addition, endocrine signaling is typically less specific than neural signaling. The same hormone may play a role in a variety of different physiological processes depending on the target cells involved. For example, the hormone oxytocin promotes uterine contractions in women in labor. It is also important in breastfeeding, and may be involved in the sexual response and in feelings of emotional attachment in both males and females. In general, the nervous system involves quick responses to rapid changes in the external environment, and the endocrine system is usually slower actingtaking care of the internal environment of the body, maintaining homeostasis, and controlling reproduction (Table 17.1). So how does the fight-or-flight response that was mentioned earlier happen so quickly if hormones are usually slower acting? It is because the two systems are connected. It is the fast action of the nervous system in response to the danger in the environment that stimulates the adrenal glands to secrete their hormones. As a result, the nervous system can cause rapid endocrine responses to keep up with sudden changes in both the external and internal environments when necessary. Q: Which system is capable of responding quickly to changing situations? Choices: - endocrine system - reproductive system - circulatory system - nervous system A:
Ans: nervous system

Answer the following question given this paragraph: Core electrons are the electrons that are closer to the nucleus and therefore do not participate in bonding. Q: Because core electrons are closer to the nucleus, they are not involved in what? Choices: - diffusion - splitting - fission - bonding A:
bonding
