I'm not sure about number 1 or number 6, but I know that 3 is nucleic acid and 5 is solution.
C upcoming would be the closest to future
Explanation:
Karyotyping is <u>a test to examine chromosomes in a sample of cells</u>. This test can help identify genetic problems as the cause of a disorder or disease.

The cane toad was a failure as a biological control method in Australia because:
-The greyback beetle it was supposed to be eating fed at the top of the sugarcane stalks (which were 6-8 meters in height). Cane toads cannot fly or climb and therefore couldnt feed on the beetles.
-The beetles were out during the daytime, and cane toads feed at night.
-The two species are not seasonally compatible (aren't in the same place at the same time of year).
-The toads needed moist conditions to survive, and so moved away from where they were supposed to be.
-The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives.
-Breeding habits made the cane toads a very invasive species.
