Deciliters are a measurement of volume (1 dl is about equal to 3 oz of liquid) Meters are a measure of length (1 m is about equal to 1 yard) A deciliter is equal to 1/10 of a liter A liter is 1/1000 of a cubic meter (m3) 20 deciliters = 2 liters = 1/500 m3
I calculate in SI-units. Use appropriate units for your own use. Density is mass pr. volume, like: 0.2 kg / m3 so when you have 10 m3 you just multiply the two numbers: 0.2 kg/m3 time 10 m3 = 2 kg Note that the cubic meter (m3) is shortened out by it self. So you end up with the mass alone.
A recessive trait needs two copies of an allele to be expressed. Dominant traits are expressed when either two copies of an allele are expressed OR in the heterozygote. A: Dominant (will be expressed as AA or Aa) a: recessive (will be expressed only as aa)
