The state of Michigan has faced a big problem with an invasive species of plant in its wetlands. The plant is seemingly harmless and beautiful, and while there's no argument about the beauty of it, it is actually very destructive toward the local flora and because of it the fauna as well. In order to solve the problem with the purple loosestrifes, the state of Michigan has asked for help from the professionals in the universities to find out a solution. The scientists managed to figure out a way in which they can lower significantly the density of this invasive species and mostly restore the native flora, and the salvation was in certain species of insects. Some insects are natural predators of this plant, thus they destroy it, so several species of insects have been released at the places where this plant had spread out. The effects have been excellent, as the insects did their job properly, managing to reduce significantly the amount of purple loosestifes, enabling the native flora to get its territory back.

Invasive species reduce biodiversity levels, create a nuisance, cause economic loss, and disrupt ecosystem equilibrium.
<h3>Effects of invasive species</h3>
- Invasive species tend to drive away or kill native species.
- Invasive species reduce the overall biodiversity of plants or animals in the ecosystem.
- They cause economic loss through the loss of important native species.
- They create nuisance in the environment and may be costly to get rid of.
- They affect ecosystem equilibrium by causing species change.
- They are usually difficult to manage.

Based on the symptoms present, he could be experiencing hyperglycemia.
Answer:
The dominant curled wing allele is also a recessive lethal.
Explanation:
If we look at the F2 ratio we see that :
curled wings: straight wings= 160:80
=2:1
Hence, if curled wings is considered to be a dominant trait then Curled wings * straight wings
Dd x dd
Punnet square will be as follows :
d d
D | Dd | Dd
d | Dd | dd
Hence in order to get F2
Dd x dd
Punnet square will be the same as above if the F1 cross is Dd* Dd
D d
D DD Dd
d Dd dd
if DD is lethal then the ratio is
Dd:dd=2:1
that is curled wings: straight wings=2:1
Hence, The dominant curled wing allele is also a recessive lethal.
