Biology

2. Ribonucleic acid; the intermediary translating DNA instructions into cellular actions
4. Cells Cells accountable for muscle contraction and movement
6. Cells Specialized cells participating in sexual reproduction; sperm cells (males) and egg cells (females)
8. Cells Cells possessing a cell wall, chloroplasts, a large central vacuole, and various organelles; Eukaryotic
10. Deoxyribonucleic acid; the genetic information carrier in cells
15. Variable An external factor capable of influencing the dependent variable, potentially leading to inaccuracies in conclusions
16. Variable The manipulated element in an experiment designed to observe its impact on the dependent variable
17. Complex molecules constituted by chains of amino acids, serving diverse structural and functional roles in cells
19. Group The group in an experiment exposedto the specific treatment or change being investigated
20. Cells Specialized cells forming the structural framework of bones

1. Cells Cells devoid of a cell wall, featuring a flexible membrane and various organelles; Eukaryotic
3. Variable The observed or measured aspect in an experiment, influenced by alterations in the independent variable
5. Cells Single-celled microorganisms lacking a nucleus; Prokaryotic
7. The repetition of an experiment multiple times to affirm the reliability and consistency of obtained results
9. Acids The fundamental units forming proteins
11. The unpredictable assignment of elements to different groups or conditions to ensure fairness in an experiment
12. Cells Cells with a rigid cell wall, chloroplasts, and a large central vacuole; Eukaryotic
13. Group The unchanged group in an experiment providing a baseline for comparison with the experimental group
14. Variable (Constants) Elements deliberately kept consistent in an experiment to ensure that observed effects are attributable to the independent variable
18. Cells transmitting electrical impulses and chemical signals in the nervous system
