Answer the following question given this paragraph: The genetic code is the same in all living things. This shows that all organisms are related by descent from a common ancestor. Q: What code is the same in all living things and shows that all organisms are related by descent from a common ancestor? Choices: - descendant - biochemical - intrinsic - genetic A:
genetic
Answer the following question given this paragraph: Biomes as different as deserts and wetlands share something very important. All biomes have populations of interacting species. Species interact in the same basic ways in all biomes. For example, all biomes have some species that prey on others for food. Q: Although they are as different as deserts and wetlands, all of these ecosystem units have populations of interacting species? Choices: - corals - continents - zoos - biomes A:
biomes
Q: Answer the following question given this paragraph: In the troposphere, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun. Some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes. Q: What happens to temperature in the troposphere as the altitude increases? Choices: - it increases - it disappears - it stays the same - it decreases A:
A: it decreases
Question: Answer the following question given this paragraph: Vegetative reproduction is a type of asexual reproduction found in plants. This type of reproduction occurs when new individuals are formed without the production of seeds or spores. The formation of new plants out of rhizomes or stolons is an example of vegetative reproductive, such as in the strawberry plant. Other plants use this type of reproduction to reproduce through bulbs or tubers, or shoots and suckers that form along lateral roots. See the Plant Biology concepts for additional information. Q: What kind of reproduction is vegetative reproduction? Choices: - sexual - meiosis - mitosis - asexual A:
Answer: asexual

Answer the following question given this paragraph: 2.3 | Biological Molecules By the end of this section, you will be able to: Describe the ways in which carbon is critical to life Explain the impact of slight changes in amino acids on organisms Describe the four major types of biological molecules Understand the functions of the four major types of molecules The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements. Q: Biological macromolecules are organic, which means that they must contain what? Choices: - hydrogen - aluminum - oxygen - carbon A:
**Answer**
carbon
Answer the following question given this paragraph: Which of the following statements about the anatomy of a mollusk is false? a. Mollusks have a radula for grinding food. A digestive gland is connected to the stomach. The tissue beneath the shell is called the mantle. The digestive system includes a gizzard, a stomach, a digestive gland, and the intestine. Mollusks have a muscular foot, which is used for locomotion and anchorage, and varies in shape and function, depending on the type of mollusk under study. In shelled mollusks, this foot is usually the same size as the opening of the shell. The foot is a retractable as well as an extendable organ. The foot is the ventral-most organ, whereas the mantle is the limiting dorsal organ. Mollusks are eucoelomate, but the coelomic cavity is restricted to a cavity around the heart in adult animals. The mantle cavity develops independently of the coelomic cavity. The visceral mass is present above the foot, in the visceral hump. This includes digestive, nervous, excretory, reproductive, and respiratory systems. Mollusk species that are exclusively aquatic have gills for respiration, whereas some terrestrial species have lungs for respiration. Additionally, a tongue-like organ called a radula, which bears chitinous tooth-like. Q: What do aquatic mollusk species use for respiration? Choices: - lungs - phototropism - pores - gills A:
gills
