How do you calculate the average atomic mass of oxygen 99.76 of atoms with mass of 15.99 amu. .038 with mass of 17 amu.. 0.20 with mass 18.0amu?

To calculate the average atomic mass of oxygen, multiply the mass of each isotope by its relative abundance (as a decimal), and then sum the results. For the given isotopes:

[ \text{Average atomic mass} = (0.9976 \times 15.99) + (0.00038 \times 17) + (0.0020 \times 18.0) ]

Calculating this gives:

[ (0.9976 \times 15.99) + (0.00038 \times 17) + (0.0002 \times 18) \approx 15.999 ]

Thus, the average atomic mass of oxygen is approximately 15.999 amu.

What member of the family carry the allele for the trait?

The member of the family that carries the allele for the trait is typically referred to as a carrier. Carriers have one copy of the allele that can express the trait, often recessive, but may not show the trait themselves. This means they can pass the allele to their offspring, potentially leading to the trait being expressed in the next generation if the other parent also carries the allele. Identifying carriers is crucial in genetic counseling and understanding inheritance patterns.

What plant has holes in it?

The plant known for having holes in its leaves is the Monstera deliciosa, commonly referred to as the Swiss cheese plant.
