Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.
Declines rapidly, increases more rapidly, reaches carrying capacity and enters a phase of exponential growth.
Answer:
phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale
Explanation:
A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.
