The genes appeared in a later generation, they were dormant.
Telomeres are the tiny areas at the tip of chromosomes that grow shorter each time a cell divides and eventually disappear ending cell replication. Telomeres functions to protect the ends of chromosomes from sticking to each other. Additionally they protect genetic information during cell division because a short piece of each chromosome is lost every time DNA is replicated.
Answer:
Xeromorphic adaptation is a type of adaptation which helps the plant body to retain water in dry environments.
Explanation:
Xeromorphytes are those plants having Xeromorphic adaptation. These plants adapt certain characteristics which enable them to store more water and lose less water. They have wax and hairs on their skin which reduces the transpiration process so they are able to survive in dry ecosystems of desert. They also have deep roots which absorbs water for it. For example, cactus plants.
<span>The
conceptual model provides a concept of how the components of an atom
are arranged, implying a similarity of the forces acting between those
components.
It is important to note that the conceptual model is not necessarily
correct or accurate. It simply provides a model which forms the basis
for the discussion of the concepts involved.
Science is all about the discussion -- with the expressed aim of
improving the conceptual model to the point that it is self-consistent
and consistent with the existing body of accepted knowledge. [The
hardest part is knowing when and how to question the body of accepted
knowledge.] </span>
