Compare and contrast the adaptations of free-living flatworms and parasitic flatworms
sammy [17]

<u>Answer:</u>

Free-living flatworms have developed a nervous system which helps them to sense the food. They have a head at one end of the body and each side of the head has sensory cells. These cells help them to sense chemicals and other movements around them.

 

While Parasitic flatworms don't have any nervous or digestive system as they live on the food digested by the host. They have special hooks attached to their head which help them to attach a host. They have developed some covering called 'teguments' which protect them from digestive liquids.

Nuclear power has come under higher scrutiny in recent years. Which statement would make the strongest for the use of nuclear po
Tamiku [17]

The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.

I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.

Have a great day. Keep asking questions!
