Q: The force that a magnet exerts on certain materials is called what? Read this paragraph and choose the correct option from the provided answers: The force that a magnet exerts on certain materials, including other magnets, is called magnetic force . The force is exerted over a distance and includes forces of attraction and repulsion. North and south poles of two magnets attract each other, while two north poles or two south poles repel each other. A magnet can exert force over a distance because the magnet is surrounded by a magnetic field . In the Figure below , you can see the magnetic field surrounding a bar magnet. Tiny bits of iron, called iron filings, were placed under a sheet of glass. When the magnet was placed on the glass, it attracted the iron filings. The pattern of the iron filings shows the lines of force that make up the magnetic field of the magnet. The concentration of iron filings near the poles indicates that these areas exert the strongest force. You can also see how the magnetic field affects the compasses placed above the magnet.

Choices: - stellar force - velocity force - centripetal force - magnetic force A:

Q: What do animals require to grow and develop? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - sunlight - sucrose - carbon dioxide - food A:
