Aplant with purple flowers is allowed to self-pollinate. generation after generation, it produces purple flowers. this is an example of

True breeding

Explanation:

True breeding is a breeding in which parents produce the offspring which carry same phenotype.  

The parents in true breeding are homozygous for every trait.  

True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place.  

For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
