Ileum is the longest and the last part of small intestine where the highest amount of absorption takes place.
The nutrients from the food that we consume gets absorbed as the food passes through our intestinal tract. The digestion and absorption of food continues all the way till it is excreted out from our body.
The small intestine begins after the stomach and contains three part, namely, the duodenum, jejunum and ileum. It performs the function of digesting the food which it receives from the stomach. Nutrients like carbohydrates, fats, proteins etc. are absorbed here. The absorption of nutrients and minerals starts in the duodenum. The main function of jejunum is to absorb important nutrients like fatty acids, sugars etc. Ileum is the longest part of the small intestine and it is where the largest amount of absorption takes place.

Very important, the study of genetics for life is to know the nature of inherited disorders in humans. By knowing the nature of these inherited disorders, we can avoid them.
An investigation of heredity in genetics was carried out by Mendel using garden peas. Mendel showed that the inheritance of certain biological genes from traits in pea plants followed certain patterns, now referred to as Mendel's Laws.
The inheritance of traits in living things is controlled by chromosomes and genes. Both functions as carriers of genetic information and can determine the nature of the offspring.

What role does mitosis play in fetal development? how does the same dna get in every cell?.
The replicated genome is divided (known as karyokinesis) and the cytoplasm is segregated during mitosis (cytokinesis). The lungs are the last significant organ to be finished.
As a result, during a mitotic cell cycle, the number of chromosomes remains constant, but during the S phase, the amount of DNA per chromosome doubles (each chromosome initially has one chromatid before dividing into two identical sister chromatids by mitosis). Throughout the course of the pregnancy, the embryo grows into a fetus. A neonate, or newborn, is the term used to describe the fetus at birth. Three main periods make up prenatal development.
The fetal stage, which lasts from the ninth week till birth, follows the embryonic stage, which lasts from the third to the eighth week after conception.

Dispersal refers to the movement of individuals away from their natal group or home range to establish a new home range and potentially reproduce.
Dispersal allows primates to increase their home range and explore new areas that may have more resources or less competition. This can be especially important for males as it increases their chances of finding a new mating opportunity and reproducing.

The process by which two or more atomic nuclei "fuse" to form a single heavier nucleus is known as nuclear fusion.
In the process of nuclear fusion:
The resulting single nucleus has a mass that is lower than that of the two original nuclei, indicating that matter is not conserved. The fusing nuclei's mass is converted into energy, which is released. The mass difference between when nuclei fuse and when an atom is formed is the source of this energy.

Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized.
Sexual reproduction is the process of creating a child in which the male parent's sperm fertilizes the female parent's egg.
They gave birth to children who differ genetically from both of their parents. The meiotic process produces gametes, which have half as many chromosomes as their parent cells. At the moment of conception, this number of chromosomes is restored. When a zygote is formed, the number of chromosomes is equal to that of all body cells. One sex chromosome, either X or Y, and all autosomes are present in each gamete in one copy. All of the autosomes are duplicated in zygotes. The XX or XY chromosome is the sex chromosome.
