Copied but correct answer.

Answer: C (She hasn't fastened the slide to the stage

Explanation:

In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.

If the microscope is not plugged it light can not come up.

If there are no specimen on the slide,the slide will still as transparent image at the focus.

No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.

Scrat [10]

Complete question:

The San Marcos salamander, Eurycea nana, is a light reddish-brown

translucent salamander about 2-5 cm in length. E. nana is found only in

Spring Lake and a portion of the San Marcos River.

Which human activity would most likely decrease the ability of the

salamanders to survive?

The addition of a new food source into the river that limits competition for

resources

Tourism that helps fund the educational programs related to river ecosystem

conservation

Public transportation that reduces the number of automobiles that contribute to

pollution runoff into the river

Increasing water consumption that decreases the flow of clean water from the

springs that feed the river

Answer:

Increasing water consumption that decreases the flow of clean water from the springs that feed the river

Explanation:

In this question we are required to state the human activity that may likely cause the reduction in the survival rate of the salamander.

the first three options in the question are not the answer to this question. this is because options 1,2,3 would have positive impacts on the Salamander. these positive impacts would increase the ability of the salamander to survive and not decrease it as the question says.

the correct answer is the last option. that is the 4th option. because it has to do with decreasing the amount of water that flows in to the Salamanders habitat by human activities. if humans increase water consumption, then the flow of clean water would reduce. This would then have a negative effect on the Salamander.
