Question

17 multiple answer 2 points which physical features are used to characterize aquatic biomes? (choose all that apply) salinity types of animals that dominate the biome sunlight water temperature 18 multiple choice 2 points what is the significance of methane as a greenhouse gas in climate change? it absorbs less heat than carbon dioxide, making it less significant in climate change. it reflects sunlight away from the earth, cooling the planet. it has a minimal impact on the greenhouse effect and is considered harmless. it is more efficient at trapping heat in the atmosphere than carbon dioxide, contributing significantly to the greenhouse effect. 19 multiple choice 2 points the body type, form or physical traits of an organism is its diplotype phenotype haplotype genotype

Explanation:

1. Aquatic biomes are characterized by physical - features like salinity, sunlight availability, and water temperature. The types of animals are not physical features but biological components.
2. Methane is a potent greenhouse gas. It is more efficient at trapping heat in the atmosphere than carbon - dioxide, contributing significantly to the greenhouse effect.
3. The body type, form, or physical traits of an organism are its phenotype. Genotype refers to the genetic makeup, haplotype is a set of DNA variations, and diplotypes are related to paired haplotypes.

Answer:

1. salinity, sunlight, water temperature
2. It is more efficient at trapping heat in the atmosphere than carbon dioxide, contributing significantly to the greenhouse effect.
3. phenotype
