It protects the tree from disease since it has a modified gene which is essential to the resistance for the pine tree. Artificial DNA Technology modifies which is what allows for the changes to occur. Pine trees without artificial modified gene for resistance will die and able to be infected.

IrinaVladis [17]

Answer:

The correct answer is The drug binds to the 30S small ribosomal  subunit eukaryotes have 40S small sub unit.

Explanation:

Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.

 Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.

 As eukaryotes contain 40S ribosomal  subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.

Scientists theorize that Australia was once part of a larger mainland area but due to plate tectonics, broke away. According to
Greeley [361]

A large assortment of plant dispersal mechanisms.

Explanation:

Pretty much everything can be explained about Australia, as to where it was in the past, with which other large landmasses it was connected, its flora, its isolation from the other continents... One thing that still needs explaining is the large assortment of plant dispersal mechanisms, which is not typical for well established islands.

The reason as to why this is weird and hard to explain is because the well established islands have flora that is well adapted to their living conditions, and also it lacks competition from outside. In other words, they rule the place. The plants in Australia though exhibit dispersal mechanisms that are typical for the plants of the continental masses that are connected, so it causes big problem in explaining it.
