Approximately twenty plant species provide about 90% of the world's food. All major food crops, including corn, wheat, and soybe

ans, are becoming more and more genetically modified (GM) and exhibit less and less genetic variation. The crops we grow are drought tolerant and able to withstand herbicide spraying. They are more resistant to insect pests. One wild relative of corn called milpilla or Zea diploperennis, is exceptionally disease-resistant and is the only perennial in the corn family. Zea diploperennis grows on only one mountain in western Mexico.
There are conflicting opinions about the use of GM crops. Imagine this scenario: Today we are faced with diseases we have never had to combat before; HIV-AIDS, ebola. Imagine our agricultural corn crops are hit by a similar virulent pathogen; one that attacks members of the Zea species. Given the history of corn in the western hemisphere, what would be the best strategy for survival of the Zea species?

A)
Conduct research to find a way to kill the pathogen.
B)
Decrease the gene variation in favor of more GM corn varieties.
C)
Increase genetic variation and breed plants to contain the wild variety.
D)
Conduct research to find a natural predator of the disease-causing pathogen.

kotegsom [21]

Answer:

The correct answer is - vestibular.

Explanation:

Vestibular is the inner ear that helps in the sense of balance in vertebrates, that helps in the keeps an individual balanced. The vestibular system is the part of the inner ear that coordinate between movement with balance.

It is also helps in spatial orientation in an individual. It is something that helps in the sensing the change in orientation and movement that leads to balancing. Vinnie is standing in one leg with arms in the air, it is possible due to the vestibular sense that prevent falling.

Thus, the correct answer is - vestibular.

Which section of the brain is responsible for coordinating muscle movements
jarptica [38.1K]

Answer:

The cerebellum (back of the brain) and the brainstem (middle of the brain)

Explanation:

Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;

  • Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
  • Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.

Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.
