Answer:
There must have two white genes to become white.
Explanation:
In order to a mouse to have white fur, both of their genes must be white. In the punnet square, you have a Black (BB) and a white (bb). If they have offspring, all of them have one black (Dominant) and one white (recessive). The black gene overpowers the white gene, so they come out black.
Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity, =
Pupil has a diameter, d = 8.5 mm
= 8.5 x m
Radius of the eye, r = 4.25 x m
∴ Area of the eye, A =
=
=
Let be the minimum number of photons.
Therefore, =
x A
= x
= W
Thus the minimum number of photons is given by
where E =
=
=
Therefore, =
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
