The dominant allele for dark-colored hair is represented as the capital letter 1 point D. The recessive allele for light-colored hair is represented as the
lowercase letter d. A female with the genotype DD is crossed with a male
Dd genotype. What is the probability that the offspring will have dark-
colored hair?

Explanation:

Ok so there is four letters, 3D and 1d. The dominant allele for dark-colored hair is represented as the capital letter D. The recessive allele for light-colored hair is represented as the  lowercase letter d. Think of each D and d  as 25% so D+D+D= 75% and that leaves the 1d as 25%.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

the answer is c. it will give up it's valence electron to the other atom.
