Answer the following question given this paragraph: Some insects use siphoning, as if sucking through a straw, like moths and butterflies. This long mouth-tube that they use to suck up the nectar of the flower is called a proboscis . Some moths, however, have no mouthparts at all. Some insects obtain food by sponging , like the housefly. Sponging means that the mouthpart can absorb liquid food and send it to the esophagus. The housefly is able to eat solid food by releasing saliva and dabbing it over the food. As the saliva dissolves the food, the sponging mouthpart absorbs the liquid food. Q: The long mouth-tube that some insects use to suck up the nectar of the flower is called what? Choices: - stamen - prosthesis - pistil - proboscis A:
proboscis
Answer the following question given this paragraph: Potassium is a soft, silvery metal that ignites explosively in water. It easily loses its one valence electron to form positive potassium ions (K + ), which are needed by all living cells. Potassium is so important for plants that it is found in almost all fertilizers, like the one shown here. Potassium is abundant in Earth's crust in minerals such as feldspar. Q: Potassium is a soft, silvery metal that ignites explosively in what? Choices: - air - cold - acid - water A:
water
Q: Answer the following question given this paragraph: Coronary Arteries Coronary arteries supply blood to the myocardium and other components of the heart. The first portion of the aorta after it arises from the left ventricle gives rise to the coronary arteries. There are three dilations in the wall of the aorta just superior to the aortic semilunar valve. Two of these, the left posterior aortic sinus and anterior aortic sinus, give rise to the left and right coronary arteries, respectively. The third sinus, the right posterior aortic sinus, typically does not give rise to a vessel. Coronary vessel branches that remain on the surface of the artery and follow the sulci are called epicardial coronary arteries. The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery. The larger anterior interventricular artery, also known as the left anterior descending artery (LAD), is the second major branch arising from the left coronary artery. It follows the anterior interventricular sulcus around the pulmonary trunk. Along the way it gives rise to numerous smaller branches that interconnect with the branches of the posterior interventricular artery, forming anastomoses. An anastomosis is an area where vessels unite to form interconnections that normally allow blood to circulate to a region even if there may be partial. Q: What vessels supply blood to the myocardium and other components of the heart? Choices: - specialized arteries - rapid arteries - surface arteries - coronary arteries A:
A: coronary arteries
Question: Answer the following question given this paragraph: Communications satellites carry solar panels to provide energy for their missions. Q: What do communication satellites carry and use to provide energy during their missions? Choices: - geothermal panels - batteries - infrared panels - solar panels A:
Answer: solar panels

Answer the following question given this paragraph: 8.1 Linear Momentum and Force Linear Momentum The scientific definition of linear momentum is consistent with most people's intuitive understanding of momentum: a large, fastmoving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as. Q: The product of a system's mass multiplied by its velocity is called what? Choices: - variation momentum - magnetic momentum - horizontal momentum - linear momentum A:
**Answer**
linear momentum
