Here’s one! Huge farming companies genetically modified foods to withstand round up. You might know round up as a weed killer. It’s marketed safe with no harming chemicals to humans. That is completely wrong and have been proven to cause many chronic illnesses including cancer. These foods are modified to not react with round up and only to kill the weeds all around the plants. Even though the food looks ok it’s really not. The round up is all over the food. Then we eat it and well bad chemicals get absorbed into are body.
I hope this is some of what you were looking for. If not I hope you enjoyed my fun fact ;) good luck.
Answer:
B. interconnected
Explanation:
All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.
Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.
Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.
Why not D: They interact with each other consistently, so they're not separate or segregated.
Answer: Homologous structures
Explanation: They are structures which have similarities in various organisms but carry out opposite functions. This is the opposite of analogous structures
The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.
Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
