When mendel crossed plants that had always produced only purple flowers with ones that had always produced only white flowers, what was the outcome of the first-generation cross?

It will produce 100% heterozygous purple flowers.

Explanation: First generation cross have homozygous parents. Purple colored flowers are dominant (XX) and the recessive the white colored flowers are (xx). If we cross both parents it will produce four heterozygous purple colored flowers.

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.

tissue

explanation:

it is actually formed by geoup of cells which is tissue
