The Michigan forests contain a variety of tree species. What happens to the tree population when a forest losses its diversity; when only one tree species dominates an area? Students in biology class conducted the following simulations to predict the effects oon one tree species due to the presence of an invasive insect species: the hemlock woolly adelgid. Simulation #1 - 1. 28 students were given a card marked with H for hemlock 2. Each student moves around the room to meet three other students and write their names on their card. 3. The teacher represents the hemlock woolly adelgid.. He touches one student who dies and sits down. That student reads the names on his/her card. 4. Each student named, also dies and also reads the names on their cards. 5. Continue to all the students sitting have read the names on their cards. Count the number of students still standing. Simulation #2 1. Students are given cards marked H - hemlock; JP - jack pine; F - balsam fir; A - aspen; B - birch. 2. Repeat steps #2 - #5 from Simulation #1. 3. This time ONLY the students marked H will sit down. The other species of trees do not die. Based on the students' simulations, what conclusion can be drawn?A)Biodiversity halts the impact of disease and/or insect damage in an ecosystem.
B)Planting hemlocks in stands by themselves will save the other tree species growing throughout Michigan.
C)By planting a variety of tree species, you reduce the impact of specific insect damage on a forest ecosystem.

Describe how turning off the electric current in an industrial electromagnet affects magnetic fields

Answers

Electromagnets are used in a number of everyday devices.

One useful characteristic of an electromagnet is the fact that you can vary its magnetic force by changing the amount and direction of the current going through the coils or windings around it. Loudspeakers and tape recorders are devices that apply this effect.Some electromagnets can be very strong and its power can be readily turned off and on. Junk yard electromagnets, common doorbells and electromagnetic locks are examples.Electromagnets can also be used to create continual motion when opposed by other electromagnets or permanent magnets. Examples include electric motors and maglev trains.
