Answer:

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

The biggest issue would probably be number I. The other concerns (II, III, IV, V) would probably be easy to solve with the some specific chamber characteristics.
The fact that the moon has no atmosphere it means that it doesn't retain neither CO_{2} nor O_{2}. Even with the appropriate chamber characteristics to retain such gases, how would the crop in the first place have so much free CO_{2} to use.
Temperature could be managed inside the chamber as well as accelaration. The period of day light would be long and intense. As for the water, once plants evaporate water when they breath at night (instead of doing photosynthesis), that water could be all collected and condensed by the chamber to be used again during the day light period.

Answer:

<h3><em><u>Archaea</u></em></h3>

Explanation:

Archaea contains DNA not held in a nucleoid or nucleus. They tend to live in harsh temperatures/climates and are found in thermal vents, and they can survive on certain non-organic substances.

Now bacteria contains a nucleoid which holds the DNA, and Eukarya (plant and animal cells) also have DNA but have membrane-bound organelles that are like nucleus.

Anni [7]

Answer:

a virus, because it requires a host cell to reproduce

Explanation:

  • a bacterium, because it is contagious
  • a fungus, because it infects livestock
  • a protist, because it is microscopic
  • a virus, because it requires a host cell to reproduce

The correct answer would be <u>a virus because a virus is the only microbe that cannot reproduce on its own without a host</u>. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.

<u>In lytic cycle</u>, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.

<u>In lysogenic cycle</u>, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.
