Anaphase 1 -- a homologous pair is being pulled apart by spindle fibers.
Anaphase 2 -- the spindle fibers attaches to the centromere and pulls 2 pieces of the same chromosome apart.
The difference is significant because the chromosomes are aligned in different directions.
let me know if you need more information.

Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
Better adapted organism includes weeds, will replace some or all of the planted flower species.
Biosphere is one of the layers surrounding the earths surface where life exists. It represents the ecological system intergrating living things and their interactions with the environment relating to the other layers (hydrosphere, atmospheres, geosphere and the lithosphere). Photoautotrophs are organisms that make their own food using sunlight in a process called photosynthesis. They are responsible for the food supply in the biosphere.
