Answer:
Plants and animals took up different evolutionary pathway millions of years ago.
In the prebiotic earth, the CO2 levels were insanely high, and the solar input was quite high due to which the initially evolved cells were photosynthetic , so that they can harness the solar energy, and because they need a carbon source, they relied on the Carbon from CO2.
In this process, the atmospheric gaseous content changed, as predecessors of plants gave out Oxygen over millions of years.
Gradually , the atmosphere was now oxygen rich and hence predecessors of animals evolved a mechanism to utilise this oxygen , and as a byproduct started releasing CO2.
Over the next years , these two diverse groups specialised and hence , became increasingly different.
Explanation:
Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes.
The modern bread wheat which is the product of multiple instances of hybridization of wheat species in the question is an example of : Cell division and self fertilization
<h3>Similariity between modern wheat and wheat found in middle eastern farms </h3>
Modern Wheat used for bread is similar to wheat found in the middle eastern farms 10,000 years ago in that they underwent several hybridization process of wheat species before been used as modern bread wheat. This process is an example of cell division and self fertilization.
Hence we can conclude The modern bread wheat which is the product of multiple instances of hybridization of wheat species in the question is an example of : Cell division and self fertilization

Answer:
Anaerobic respiration
Explanation:
As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.
The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.
