Answer the following question given this paragraph: The classroom in Figure above has artificial light sources in addition to natural sunlight. There are fluorescent lights on the ceiling of the room. There are also projectors on the ceiling that are shining light on screens. In these and most other artificial light sources, electricity provides the energy and some type of light bulb converts the electrical energy to visible light. How a light bulb produces visible light varies by type of bulb, as you can see in Table below . Incandescent light bulbs, which produce light by incandescence, give off a lot of heat as well as light, so they waste energy. Other light bulbs produce light by luminescence, so they produce little if any heat. These light bulbs use energy more efficiently. Which types of light bulbs do you use?. Q: Aside from light, incandescent light bulbs also give off what that wastes energy? Choices: - temperature - humidity - electricity - heat A:
heat
Answer the following question given this paragraph: 15.1 | Features of the Animal Kingdom By the end of this section, you will be able to: List the features that distinguish the animal kingdom from other kingdoms Explain the processes of animal reproduction and embryonic development Describe the hierarchy of basic animal classification Compare and contrast the embryonic development of protostomes and deuterostomes Even though members of the animal kingdom are incredibly diverse, animals share common features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter. This form of obtaining energy distinguishes them from autotrophic organisms, such as most plants, which make their own nutrients through photosynthesis and from fungi that digest their food externally. Animals may be carnivores, herbivores, omnivores, or parasites (Figure 15.2). Most animals reproduce sexually: The offspring pass through a series of developmental stages that establish a determined body plan, unlike plants, for example, in which the exact shape of the body is indeterminate. The body plan refers to the shape of an animal. Q: What do animals require to grow and develop? Choices: - sunlight - sucrose - carbon dioxide - food A:
food
Q: Answer the following question given this paragraph: Pubic lice , like the one in Figure below , are insect parasites that are transmitted sexually. They suck the blood of their host and irritate the skin in the pubic area. Q: What are insect parasites transmitted sexually? Choices: - chlamydia - pinworms - deer ticks - pubic lice A:
A: pubic lice
Question: Answer the following question given this paragraph: Chemical reactions that take place inside living things are called biochemical reactions . Living things depend on biochemical reactions for more than just energy. Every function and structure of a living organism depends on thousands of biochemical reactions taking place in each cell. Q: What do you call chemical reactions that take place inside living things? Choices: - contaminated reactions - autonomous reactions - physical reactions - biochemical reactions A:
Answer: biochemical reactions

Answer the following question given this paragraph: Both flukes and tapeworms are parasites with vertebrate hosts, including human hosts. Flukes live in the host's circulatory system or liver. Tapeworms live in the host's digestive system. Usually, more than one type of host is required to complete the parasite's life cycle. Look at the life cycle of the liver fluke in Figure below . As an adult, the fluke has a vertebrate host. As a larva, it has an invertebrate host. If you follow the life cycle, you can see how each host becomes infected so the fluke can continue its life cycle. Q: Both flukes and tapeworms are parasites with what kind of host? Choices: - insect - trees - cells - vertebrate A:
**Answer**
vertebrate

Answer the following question given this paragraph: Cells that are communicating may be right next to each other or far apart. In juxtacrine signaling , also known as contact-dependent signaling, two adjacent cells must make physical contact in order to communicate. Cell communication may also occur over short distances, which is known as paracrine signaling , or over large distances, which is known as endocrine signaling . Q: Cell communication that occurs over short distances is known as what? Choices: - hypersignaling - contraposition signaling - cell echo - paracrine signaling A:
(Answer)
paracrine signaling
