After anaphase Telophase occur.
Explanation:
The M-phase of cell division involves two steps:
- Karyokinesis: Division of nucleus.
- Cytokinesis: Division of cytoplasm.
Karyokinesis has the folloeing steps:
- Prophase: The nuclear membrane disappears and the cromatin fiber begins to condense and form chromosome.
- Metaphase: The metaphase chromosome are well distinct and are arranged on the equilateral plane. And the kinetochore ttaches to the spindle.
- Anaphase: The spindles begin to contract and the sister chromatids begin to separate and move towards respective poles.
- Telophase: Chromatids are already at the poles and they become inconspicuos. The nuclear membrane begins to appear.
Telophase marks the end of Karyokinesis and soon the cytokinesis begins.
In plants cytokinesis occurs by cell plate formation.
In animal cell cytokinesis occurs by invagination.

Answer:
sunlight
Explanation:
Undergrowth plants can be defined as the undergrowth or undergrowth that is found within tropical rainforests, also occurring in temperate forests, which forms a vital ecological niche in the forest ecosystem to which it belongs. In this highly humid system shaded by dense upper vegetation predominates the trees, shrubs, terrestrial epiphytes, mosses, fungi and other hundreds of hydrophilic species (which need a humid environment), forming exceptional and specific conditions for the maintenance of thousands of animals. .
As you may already know, plants need a lot of sunlight to stay alive. Undergrowth plants, however, are constantly shaded by tall planes, which could be a problem if these plants had not developed adaptive mechanisms to capture and need limited sunlight.
They provide the immune system with "memory" against previously encountered pathogens.
T memory cells are necessary for protective immunity against invading pathogens
If AMOC and the Gulf Stream do become weaker, the probability is that Northwest Europe is going to get cooler, or not warm as much as it otherwise would under global anthropogenic climate change. And if sea level is a little bit higher, maybe because of the Gulf Stream weakening, it only makes matters worse.
