The answer is B because the independent variable would be the hours of music playing and the dependent, which means the effect of the independent variable, would be weight or mass of the fish. In his observation he sees that the fish grow larger so that would be your dependent variable.<span />
Answer:
1. ridges and trenches (either answer is acceptable)
2. mid-atlanitc
3. subduction zone
4. molten
5. oceanic trenches
Explain:
6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.
Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
Answer:
The researcher's claim is in the same way of the observation made because from it it is inferred that in a population of bacteria with genetic variation, in which some of them have plasmids and others do not, the population survives because those bacteria with plasmids are resistant to antibiotics, if for example there were only bacteria without plasmids all bacteria would die when using antibiotics so this is an example that genetic diversity is an evolutionary advantage
