A farming community is experiencing an extended drought. Due to this, the community is low on water. The local and state governments decide to build a dam on a local river. One of the benefits for the farmers is that the dam will create a reservoir, which the farmers can use to irrigate their crops.

How could the dam affect the resources of the local watershed? Check all that apply.

A) Fish would not be able to migrate up the river to reproduce.
B) Sediment carried by the flowing river would get trapped.
C) There would be more space for forest growth.
D) The number of habitats for local wildlife would increase.
E) Birds that depend on fish may go hungry.

Always use significant figure rules. remember that these rules apply to all numbers that are measurements. if a vector that is 3 cm long represents 30 km/h, what velocity does a 5 cm long vector which is drawn using the same scale represent? a.100 km/h b.60km/h c.50km/h

What are genotypes? what are phenotypes?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
