Correct Answers

1. The steps of the scientific method include: observation, hypothesis, experimentation, analysis, and conclusion.
2. Living things display characteristics such as growth, reproduction, response to stimuli, metabolism, and adaptation.
3. Eukaryotic cells have a nucleus and membrane-bound organelles, whereas prokaryotic cells lack a true nucleus and membrane-bound organelles.
4. The main kingdoms are: Animalia (multicellular and motile), Plantae (autotrophic and have cell walls), Fungi (decomposers and have chitin in their cell walls), Protista (mostly unicellular and diverse).
5. The primary difference is that Protista generally contains organisms that are unicellular or simple multicellular, while Fungi are primarily decomposers and typically have a mycelium structure.
6. Fungi obtain nutrients through absorption, primarily through the decomposition of organic matter.
7. A phylum is a rank in biological classification below kingdom and above class; for example, Chordata (animals with a backbone).
8. Examples include: Humans (Chordata), Starfish (Echinodermata), and Insects (Arthropoda).
9. Main characteristics of prokaryotic organisms include their lack of a true nucleus, smaller size, and usually having a simple structure.
10. Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plants.
11. Homeostasis is the ability of an organism to maintain a stable internal environment; it is crucial for survival and proper functioning.
12. Cellular respiration is the process by which organisms convert glucose and oxygen into energy (ATP), vital for cellular functions.
13. The cell membrane regulates what enters and exits the cell, providing protection and support.
14. Taxonomy is the science of classification of organisms; it is important for organizing and understanding relationships among species.
15. An example of a unicellular organism is an amoeba; it plays an important role in nutrient cycling and ecosystem balance.
16. Fungi reproduce through spores, which can be produced sexually or asexually.
17. Monocots typically have one seed leaf (cotyledon), while dicots have two; they also differ in leaf venation, root systems, and flower parts.
18. An organism's habitat is the environment in which it lives; it is significant as it provides the necessary resources for survival.
19. Ribosomes are responsible for protein synthesis in the cell.
20. Enzymes are biological catalysts that speed up chemical reactions in the body, crucial for metabolism and other biological functions.
