A. The waves would be exactly the same at points A and B.
Explanation:
The seismic waves at both point A and B would be exactly the same at the two points.
Seismic waves are elastic waves that spreads out concentrically in all directions from their source.
- Both S and P waves are body waves that moves within the earth.
- In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
- At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.

I think if the whale population decreased the surface fish populations would decline due to reduced populations of algae. This can be simply explained by the fact that, if the whale population is decreased, it means that the nitrogen rich feces that is supply nutrients to the algae would also decrease and therefore decrease the population of the algae and as a result the population of of the surface fish would also decline.
I would say about her body composition is that she is within recommendations for waist circumference and percent body fat. She has a normal BMI or Body Mass Index, she has a good body composition because she is a varsity player and she is exercising her body well. So the answer in this question is she is within recommendation for waist circumference and percent body fat.
C it’s the answer for you
Answer:
Diffusion rate is 1.96 ×
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 

r =
=
= 7.5 mm = 0.75 cm
area =
×
= 1.7679 
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643
/s
Diffusion rate is 1.96 ×
