Mosses were one of the first plants to even evolve.
A population....... I think
The Human ES Cell
Culture or Embryonic Stem Cells.
They capture the thoughts because they are unforgettable and have an entire limitless developmental capability. After few months of growth, these are extraordinary cells kept maintaining the ability to create another cell ranging from muscle to nerve to blood inside the body. Any cell has the potential that makes up the body.
Answer
Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.
No crossing over
If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.
Result
At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.
Answer:
a stem
Explanation:
Plants have tubes that run through their stems and roots. These tubes carry water, minerals, and sugars. There are two types of tubes: xylem and phloem.
