Question below: (thanks!)
wel

Answer:

Frequency of SS dominant individuals is 0.57

Explanation:

The total population of rabbit is 650

Out of 650 rabbit, nearly 39 have recessive allele "s".

Hence, frequency of recessive genotype = \frac{39}{650} = 0.06

Frequency of recessive allele = \sqrt{0.06}

q = \sqrt{0.06} = 0.245

Frequency of dominant trait allele "S" p = 1-q = 1-0.245 = 0.755

Frequency of SS dominant individuals is p^{2} = 0.755^2 = 0.57

If there were no air resistance, with what speed would drops hit the Earth if they fell from a cloud 3063 m above the Earth’s su
schepotkina [342]

Answer:

Explanation:

One

d = 3063 m

a = 10 m/s^2

vi = 0

vf = ?

vf^2 = vi^2 + 2*a*d

vf^2 = 2*10*3063

√vf^2 = √61260

vf = 247.51 m/s

Two

vi = 0

vf = ?

a = 10 m/s^2

t = 18 s

a = (vf - vi) / t

10 = (vf - 0) / 18

10 * 18 = vf

180 m/s = vf

If a line crosses the y-axis at (0, 1) and has a slope of '4/5 , what is the equation of the line?
Kazeer [188]

Answer:

y = \frac{4}{5}x + 1

Explanation:

A line has a general equation of

y = mx + b

where b is the y-intercept and slope of m.

Since (0,1) is the value of y when x = 0, it is the point of intersection of the line with the y-axis, hence the y-intercept is b=1.

We are given the slope is m = \frac{4}{5}

So the equation of the line is

y = \frac{4}{5}x + 1
