Answer:
Metaphase I
Explanation:
Homologous chromosomes are paired to facilitate crossing over during prophase I of the meiosis I. This is followed by alignment of homologous chromosomes at the equator of the cell during metaphase I. The process is assisted by microtubules of spindle apparatus. The kinetochore microtubules of the spindle apparatus attach themselves to the kinetochores of chromosomes.
The two sister kinetochores of duplicated homologous chromosomes are attached to the opposite pole to align the homologous pair at the center of the cells. Metaphase I is followed by anaphase I during which homologous chromosomes move towards the opposite poles.
No. The natural selection is when the best suit fits survive. Therefore is not the idea that as an environment changes.
The equation is glucose + oxygen carbon dioxide + water and energy is produced in the form of ATP.
Explanation:
Cellular respiration is a metabolic process in which glucose combines with oxygen to produce carbon dioxide and water with energy stored as ATP.
Glucose + Oxygen gas → Carbon dioxide + Water + energy in ATP
ATP is Adenosine TriPhosphate.
In the body, during cellular respiration, oxygen gas is inhaled and carried to sites in the body where food in form of glucose obtained from plant is broken down.
When food is broken down aerobically i.e in the presence of oxygen gas, carbon dioxide and water is produced and energy is stored in form of ATP.
