I think that scientist should build a habitat we’re the endangered animals could go free.By scientists building a habitat I mean giving the endangered animals a space to feel safe.Another way scientists could help endangered animals , would be to try and reproduce, the animal.For example scientist could help out with giving the animals hormones to be able to reproduce.And lastly scientists could do experimentation on the endangered animals to see if the animal ever were to go extinct how they could reproduce a new species.
Answer:
[α] = -77.5° / 
Explanation:
Given;
Mass of optically pure substance in the solution = 10 g
Volume of water = 500 mL
Length of the polarimeter, l = 20 cm = 20 × 0.1 dm = 2 dm
measured rotation = - 3.10°
Now,
The specific rotation ( [α] ) is given as:
[α] = 
here,
α is the measured rotation = -3.10°
c is the concentration
or
c = 
or
c = 
or
c = 0.02 g/mL
on substituting the values, we get
[α] = 
or
[α] = -77.5° /
Steam rises to the top and stays there
