What’s the question exactly?? Is it like a true or false type of thing??
Answer:
1/4 or 25%
Explanation:
<em>The chance that their children would have severe (;ethal) achondroplasia would be 25% or 1/4.</em>
From the illustration:
AA genotype is physically lethal,
Aa genotype conditions achondroplasia, and
aa genotype conditions normal height.
Now, a male whith achondroplasia (Aa) had children with a female with achondroplasia (Aa):
Aa x Aa
Progeny = AA, 2Aa, aa
<u>Out of the 4 children produced from the cross, one of them has </u><u>AA </u><u>genotype which represents severe (lethal) conditions. Thus, the chance that their children would have severe (lethal) achondroplasia is 1 out of 4 or 25%.</u>
Density is mass divided by volume. The mass of the block is 10 grams. The volume of the block is 2 mL: the water changes from the 3 mL line to the 5 mL when the block is added, so the block must be 5-3= 2 mL.
So, the density is 10 g / 2 mL = 5 g/mL.
Hope this helps!
