Answer:
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Explanation:
Answer:
white for the first one and brown for the secound one
Explanation:
Answer: a star expels most of its outer material until only the hot core remains, which then settles down to become a young a white dwarf
Explanation:
Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
- Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
- A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
- Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

Answer:
C
Explanation:
From reading what the process is, I think the answer should be C. The definition always says that you get energy from a chemical reaction and the products are CO2 and water. That can only mean that you have a hydrocarbon burning.
Chemically it looks like
C6H12O6 + 6O2 ====> 6CO2 + 6H20
