Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.

Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.

A restriction enzyme has a 4 bp recognition sequence. Assuming equal frequency of all four bases in a 5,000 bp linear section of
I am Lyosha [343]

Answer: 20 fragments

Explanation:

This particular restriction enzyme has a 4 bp (base pair) recognition sequence therefore it will cleave once every 4ⁿ bases where n indicates the number pf bases in the recognition sequence.

  • The recognition sequence is 4 bp therefore this restriction enzyme cleaves once every 4⁴ = 256 bases. This is the length of the restriction fragment.
  • Calculate the number of fragments by dividing the total number of bases ( where you assume equal frequency of bases ie. A+T = C+G) by the length of the restriction base.
  • therefore 5000bp/256bp = <u>19,53</u> now this number ca n be rounded up to 20.
  • The expected number of fragments on the electrophoresis gel will be 20 fragments.
