Answer:
a stem or a leaf
Explanation:
Cuttings can be made from any part of the plant. Most frequently, however, either a stem or leaf is used. A stem cutting includes a piece of stem plus any attached leaves or buds. Thus, the stem cutting only needs to form new roots to be a complete, independent plant.
Answer:
The first multicellular organisms occurred from symbiosis (cooperation) of different species of single-cell organisms, each with different roles. Over time these organisms would become so dependent on each other they would not be able to survive independently, eventually leading to the incorporation of their genomes into one multicellular organism.
Explanation:
Multicellularity has evolved independently at least 46 times in eukaryotes,[5][6] and also in some prokaryotes, like cyanobacteria, myxobacteria, actinomycetes, Magnetoglobus multicellularis or Methanosarcina. However, complex multicellular organisms evolved only in six eukaryotic groups: animals, fungi, brown algae, red algae, green algae, and land plants.[7] It evolved repeatedly for Chloroplastida (green algae and land plants).
Oswald Avery used chemical analysis to show the genetic material in bacteria is DNA.
the questions that should be asked is what are the
environmental factors contributing to the increased population? Has the
conditions helped their natural reproductive abilities? How can this population
explosion be controlled? Is the increased number of pythons affecting the
natural eco system and the animals residing in it?
