Answer the following question given this paragraph: Weight measures the force of gravity pulling downward on an object. The SI unit for weight, like other forces, is the Newton (N). On Earth, a mass of 1 kilogram has a weight of about 10 Newtons because of the pull of Earth's gravity. On the moon, which has less gravity, the same mass would weigh less. Weight is measured with a scale, like the spring scale shown in the Figure below . The scale measures the force with which gravity pulls an object downward. To delve a little deeper into weight and gravity, watch this video:. Q: What is the force that pulls downward on an object and is measured by weight? Choices: - strength - work - light - gravity A:
gravity

Most are terrestrial, and many are aerial. Insects have six legs and a pair of antennae for sensing chemicals. They also have several eyes and specialized mouthparts for feeding. Insects are the only invertebrates that can fly. Flight is the main reason for their success. Insects may live in large colonies and have complex social behaviors. Insects spread disease and destroy crops. However, they are essential for pollinating flowering plants. Q: Insects are arthropods in which class?
