Q: Plants obtain the molecules for cellular function though what? Read this paragraph and choose the correct option from the provided answers: Introduction All living organisms need nutrients to survive. While plants can obtain the molecules required for cellular function through the process of photosynthesis, most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular functions, such as assembling new molecules, cells, and tissues. The conversion of the food consumed to the nutrients required is a multi-step process involving digestion and absorption. During digestion, food particles are broken down to smaller components, and later, they are absorbed by the body. Choices: - tissues - nutrients - Plants - photosynthesis A:
photosynthesis

Q: Creep, which usually takes place where the ground freezes and thaws frequently, involves movement of particles due to what force? Read this paragraph and choose the correct option from the provided answers: Creep usually takes place where the ground freezes and thaws frequently. Soil and rock particles are lifted up when the ground freezes. When the ground thaws, the particles settle down again. Each time they settle down, they move a tiny bit farther down the slope because of gravity. Choices: - friction - wind - normal - gravity A:
gravity

Q: In many species, display behaviors, like a gorilla beating on its chest, are used instead of actual physical attacks to show what? Read this paragraph and choose the correct option from the provided answers: In many species, display behaviorsrather than actual physical attacksare used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Choices: - dominance - friction - stress - aggression A:
aggression

Q: What kind of reactions absorb energy from their surroundings as they occur? Read this paragraph and choose the correct option from the provided answers: Endothermic reactions absorb energy from the surroundings as the reaction occurs. When 1 mol of calcium carbonate decomposes into 1 mol of calcium oxide and 1 mol of carbon dioxide, 177.8 kJ of heat is absorbed. The process is shown visually in Figure above (B). The thermochemical reaction is shown below. Choices: - exothermic - hydrostatic - autotrophic - endothermic A:
endothermic
