The puppies have different colored noses because of reccesive and dominant genotypes.

Genotypes are represented by letters, capital being dominant and lowercase being recessive.

For example, lets say t = pink nose and T = black nose.

If the parents have black noses, then they will pass on T genotypes.

But, they also have hidden pink nose genotypes.

These hidden genotypes are passed on to the puppies, one of the puppies gets more black nose genotypes.

If a puppy gets tt, they will have a pink nose.

If they get TT, they will have a black nose

If they get Tt, they will also have a black nose.

Because the black nose is dominant, its more likley for the puppies to end up with a black nose.

Water enters a 4.00-m3 tank at a rate of 6.33 kg/s and is withdrawn at a rate of 3.25 kg/s. The tank is initially half full.

olga55 [171]

Answer:

At the start of the process, the volume not occupied by the water is 2 m3

Explanation:

At the start of the process you have a half full tank. It means that also a half is empty (not occupied by water).

Since the volume is 4 m3, 2 m3 are full (occupied by water) and 2 m3 (not occupied by water).

The volume in time will be

$V(t)=V_0+(f_i-f_o)*t\\\\V(t) = 2 +(6.33/1000-3.25/1000)*t=2+0.00308*t \, \, [m3]$

1) Why do astronomers use different measurement systems to discuss distance in the universe?

Ad libitum [116K]

1) Astronomers use different measurement systems to discuss distance in the universe C) because they allow the numbers to be more manageable.

The numbers are so huge that astronomers need different units to express them.

2) The measurement system with the largest value is C) the Parsec .

1 Parsec = 3.26 ly = 2.06 × 10⁵ AU
