Question

1 the study of the relationships between organisms.
2 an electron carrier.
3 coating that covers and protects viral dna/rna.
4 protein that allows h+ to re - enter mitochondrial matrix.
5 sugar regenerated in the krebs cycle.
6 rod - shaped prokaryotes.
7 an original chromosome attached to its copy.

Explanation:

1. Ecology is the study of relationships between organisms.
2. NAD+ and FAD are common electron - carriers in cellular processes.
3. The capsid is the protein coating that covers and protects viral DNA/RNA.
4. ATP synthase is the protein that allows H+ to re - enter the mitochondrial matrix and drives ATP synthesis.
5. Oxaloacetate is the sugar regenerated in the Krebs cycle.
6. Bacilli are rod - shaped prokaryotes.
7. A sister chromatid is an original chromosome attached to its copy.

Answer:

1. Ecology
2. NAD+ or FAD
3. Capsid
4. ATP synthase
5. Oxaloacetate
6. Bacilli
7. Sister chromatid
