The human populations are not limited by the carrying capacity of their ecosystems, and they are the only species on Earth that are able to perform such a thing. The main reason for this is that the humans are able to transport resources of all sorts and for all needs from very distant places. Even if there's a very large population surrounded by desert, the humans are still able to survive by simply bringing in the necessary things from other places throughout he means of transportation. Another reason is that the humans are able to change and manipulate their environment to certain extent, being able to provide for themselves even in ecosystems that naturally are nowhere near close to provide those things for them.
Answer:
Explanation:
Long-term Self-Renewal: Stem cells are capable of division while remaining unspecialized.
Differentiation
: Stem cells can divide asymmetrically, where one stem cell divides into two cells that have different cellular fates.
Induced Pluripotency
: Stem cells that have been artificially created from specialized cells are called induced pluripotent stem cells.
Considerations
: Due to their unspecialized nature, stem cells have a large research potential. The most pluripotent stem cells derive from the human embryo.
Ans.
The phloem is living plant tissue ,found in vascular plants and made up of parenchyma cells and sieve elements. Phloem performs translocation, which involves transport the soluble organic products of photosynthesis, mainly the sucrose from photosynthetic sites other plant parts where needed.
Thus, the primary function of the phloem in vascular plants is to perform 'translocation.'
