Answer the following question given this paragraph: Freshwater biomes have water that contains little or no salt. They include standing and running freshwater biomes. Standing freshwater biomes include ponds and lakes. Lakes are generally bigger and deeper than ponds. Some of the water in lakes is in the aphotic zone, where there is too little sunlight for photosynthesis. Plankton and plants, such as the duckweed in Figure below , are the primary producers in standing freshwater biomes. Q: Ponds and lakes are examples of what kind of biome? Choices: - standing lake biome - standing marine biome - standing liquid biome - standing freshwater biome A:
standing freshwater biome

Answer the following question given this paragraph: Mammals generate heat mainly by keeping their metabolic rate high. The cells of mammals have many more mitochondria than the cells of other animals. The extra mitochondria generate enough energy to keep the rate of metabolism high. Mammals can also generate little bursts of heat by shivering. Shivering occurs when many muscles contract a little bit all at once. Each muscle that contracts produces a small amount of heat. Q: Mammals generate heat primarily by maintaining a high rate of what? Choices: - reproduction - respiration - movement - metabolism A:
(Answer)
metabolism

Answer the following question given this paragraph: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing. Q: For what kind of animal is communication essential? Choices: - anti-social animals - new born animals - migrating animals - social animals A:
(A).
social animals
Ques:Answer the following question given this paragraph: Proteins can differ from one another in the number and sequence (order) of amino acids. It is because of the side chains of the amino acids that proteins with different amino acid sequences have different shapes and different chemical properties. Small proteins can contain just a few hundred amino acids. Yeast proteins average 466 amino acids. The largest known proteins are the titins, found in muscle, which are composed from over 27,000 amino acids. Q: What are the largest known proteins? Choices: - actins - hormones - keratins - titins A:

Ans:titins
