Answer the following question given this paragraph: When a warm air mass runs into a cold air mass, it creates a warm front ( Figure below ). The warm air mass is moving faster than the cold air mass. The warm air mass then flows up over the cold air mass. As the warm air rises, it cools. This brings about clouds and sometimes light precipitation. Warm fronts move slowly and cover a wide area. After a warm front passes, the warm air mass behind it brings warmer temperatures. The warm air is also likely to be more humid. Q: What results when a warm air mass runs into a cold air mass? Choices: - cool front - dry front - rough front - warm front A:
warm front

During the reaction, chemical bonds break in the reactants and new chemical bonds form in the products. Q: What type of reaction is a process in which some substances, called reactants, change into different substances, called products? Choices: - reversible reaction - physical reaction - toxic reaction - chemical reaction A:
(Answer)
chemical reaction

Answer the following question given this paragraph: Birds are endothermic tetrapod vertebrates. They are bipedal, which means they walk on two legs. Birds also lay amniotic eggs with hard, calcium carbonate shells. Although birds are the most recent class of vertebrates to evolve, they are now the most numerous vertebrates on Earth. Why have birds been so successful? What traits allowed them to increase and diversify so rapidly? Birds can vary considerably in size, as you can see from the world's smallest and largest birds, pictured in Figure below . The tiny bee hummingbird is just 5 centimeters (2 inches) long, whereas the ostrich towers over people at a height of 2.7 meters (9 feet). All modern birds have wings, feathers, and beaks. They have a number of other unique traits as well, most of which are adaptations for flight. Flight is used by birds as a means of locomotion in order to find food and mates and to avoid predators. Although not all modern birds can fly, they all evolved from ancestors that could. Q: How do bipedal creatures walk? Choices: - on twelve legs - on six legs - on four legs - on two legs A:
(A).
on two legs
Ques:Answer the following question given this paragraph: Stress is the force applied to a rock, which can cause the rock to change. The three main types of stress go along with the three types of plate boundaries. Compression is common at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries. Q: Compression, tension and shear refer to what type of force that can cause rock to change? Choices: - seismic force - process - gravity - stress A:

Ans:stress
Question: Answer the following question given this paragraph: Some of the best known types of fungi are mushrooms, which can be edible or poisonous ( Figure below ). Many species are grown commercially, but others are harvested from the wild. When you order a pizza with mushrooms or add them to your salad, you are most likely eating Agaricus bisporus , known as white or button mushrooms, the most commonly eaten species. Other mushroom species are gathered from the wild for people to eat or for commercial sale. Many mushroom species are poisonous to humans. Some mushrooms will simply give you a stomachache, while others may kill you. Some mushrooms you can eat when they are cooked but are poisonous when raw. So if you find mushrooms in the wild, don't eat them until you are certain they are safe!. Q: Mushrooms are an example of what type of organism, which includes beneficial and toxic specimens? Choices: - spores - bacteria - seeds - fungi A:
Answer:
fungi
