Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane<span>. Carbon dioxide, </span>the<span> byproduct of </span>cell<span>respiration, is small enough to readily diffuse out of a </span>cell<span>.

Answer:
The frequency of individuals with the dominant phenotype is 0.83.
Explanation:
We are provided with:
Black allele has completed dominance over brown allele
T. no of dogs (dominant)= 2000
No. of black dogs (dominant) = 1660
From Hardy-weinberg equilibrium
Frequency of individual - (individual/ Total population)
Frequency of black dogs = 1660/2000 =
0.83
So, The frequency of individuals with the dominant phenotype is 0.83
They are found in the center of the osteon within a long opening called the Haversian canal.
Rainfall is measured as depth on the surface of the Earth, typically in mm. We know the volume of water in the rain gauge: 1414 cubic centimetres. We know need to know the area of the Earth that this volume fell on. This would be the area of the funnel opening that points up to the sky to catch the rain. We know the diameter is 24 cm. So we need to determine the area of a circle with a diameter of 24 cm. The equation to use is: area = pi * radius^2. Since the radius of a circle is half the diameter, the equation is:
So area is <span>3.14159 * 12^2
= 452.39 cm^2
Volume = depth * area
depth = volume/area
depth = </span>1414/452.39
= 3.13 cm = 31.3 mm
