Metaphase
At the end of the phase the cell divides into two new cells
Answer:
Additionally, a series of GM crops have modified to express traits like an efficient use of soil nitrogen, which directly increases agricultural yield while reducing the use of fertilizers, and the new generation of diverse drought-tolerant, heat-tolerant and salinity-tolerant crops, which will increase the final yield
Explanation:
They need water,light, and carbon dioxide
Answer:
Most cells within planarians tend to be very close to their gastrovascular cavity, in addition to their external environments. Also, planarians have the ability for oxygen and carbon dioxide to diffuse through the cells on their body walls: this makes it unnecessary for these varieties of flatworms to need a dedicated bodily system.
I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm.
