Answer:
3.07% probability that the third oil strike comes on the fifth well drilled.
Explanation:
Arteries carry blood to different parts of our body. They divide into branches called capillaries to supply blood to even small organs. So, we compare arteries with tree that divides into smaller and smaller branches. Capillaries again merge and form veins to collect impure blood
The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
Answer:
Aa x Aa
Explanation:
AA x aa would produce Aa, Aa, Aa, and Aa.
Aa x Aa would produce AA, Aa, Aa, and aa.
aa x Aa would produce Aa, Aa, aa, and aa.
Answer:
transformation
Explanation:
Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.
Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.
