Answer:

A. A yeast cell reproduces itself

Explanation:

Yeast cell can reproduce asexually either by budding or fission. No matter which process, the ultimate result is cell division.

In fission, first the nucleus divides into two nuclei so that the cell contains two nuclei. Then, a constriction is laid down between the cell which eventually divides the cell into two daughter cells, each with its own nuclei.

In budding, the cell wall at one corner of the yeast softens. This portion starts to grow as a bud while still attached to the mother cell. Eventually the nucleus also divides with one daughter nuclei migrating to the bud. Finally when the bud attains the size of parent cell, cell division occurs.

Answer:

A. A yeast cell reproduces itself.

Explanation:

Should be the right answer because cell division is necessary during reproduction. Like a sponge, it separates itself (essentially the cells) and regrows the parts needed.

A purebred purple flowering plant is crossed with a purebred white flowering plant, and they produce offspring that have purple

saveliy_v [14]

The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.

On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.

The given cross represent the cross between purple (PP) and white (pp) pure breeds.
