After the digestion of carbohydrates, fats, and proteins in duodenum, the digested nutrients are absorbed in the ileum.
Ileum is a section of the small intestine, after duodenum.
Food is absorbed by diffusion and active transport. Villi on the walls of the ileum helps this process, since it can increase its surface area and provide a good blood supply, thus increase the rate of absorption.
Note that water can also be absorbed in the large intestine, those water absorbed there are the ones that cannot be absorbed in the ileum.
However, not all water is absorbed as we can notice that faeces are wet.
Answer:
Option c. anterior-posterior axis is the right answer.
Explanation:
Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior (A-P) axis during Drosophila embryogenesis. it was the first protein demonstrated to act as a morphogen. See image having more explanation.

The correct answer is the law of segregation or the law of purity of gamete.
Meiosis results into the formation of gametes. The gametes are always pure for a particular trait because each gamete carries either the dominant or the recessive factor but not both as we find in F1 individuals. This follows the 'principle of segregation', the law proposed by Mendel. This law is also called 'law of purity of gametes'. The ratio 3:1 in F2 generation of a monohybrid cross suggests that alleles are segregated and the test cross confirmed it.
