The value of a scientific variable can change. (A)

Hint hint:  That's why it's called a "variable".  If it always remained the same, then it would've been called a "constant".

How do you think car makers can design cars to limit cell phone distractions?
Dafna11 [192]

I have two (2) brilliant ideas:

1). Inside the metal that the body of the car is made of, and also between the two sheets of glass that the windows are made of, install a thin layer of material that absorbs RF (radio-wave) energy . . . like the material in the glass window of your microwave oven.  Then, no radio waves from the cellular base station can get INTO the car, and no radio waves from your phone can get OUT of the car.  The phone can't make a connection to the cellular network, you can't make or receive calls, and you can't connect to Instagram or Brainly, so you might as well just turn it off and save your battery until next time you're outside your car.

2). Somewhere inside the car, like under the dash or in the glove box, install a teeny tiny radio receiver that can recognize the signals coming OUT of your phone.  Connect it to the car's electrical system so that when it hears signals from phones inside the car, it it shuts down the car's motor so you can't start or drive. The car only works when phones inside the car are either turned off or in Airplane Mode.

My ideas are so brilliant that I really should patent them, or copyright them, or whatever you do so that other people have to pay you to use your idea. But if you want to use them, that's OK.  Just go ahead. I won't mind.

Which threats of the biodiversity is a result of plants and animals introduced to an ecosystem where they are not normally found
Nezavi [6.7K]
The answer is invasive species. Invasive species is when plants, fungus or animals that are not familiar or native to specific location and has a tendency to spread damage to environment, human health  and human economy. eg: Cane toads are originally from Australia and was moved to grasslands. These toads  are invasive species in Grasslands because they are destroying the environment and destroying the balance of wildlife (in Grasslands).

Invasive species are one of the threats to biodiversity and some ecosystems.
