How does pleasure occur? When we have sex, thephysical signals felt by the body send signals through our nerves to the brain— which reacts by releasing chemicals that make us experience even more pleasure. Some research suggests the rhythmic nature of sex and sexual stimulation creates a physi...
What is the difference between mitosis and meiosis? Which of them form gametes? How many chromosomes are in each sperm? Where does meiosis occur? Explain reproductive mitotic and meiotic cell division What are the general purposes of mitosis and meiosis...
This has been mainly due to the intrinsic difficulties of directly measuring recombination events and monitoring meiosis progression in germ cells of key representative phylogroups. So, despite being perceived as a fragile wimpy, why does the Y chromosome persist across large evolutionary time scales ...
How does trisomy 21 occur during meiosis? What is the difference between autosomal cells and somatic cells? How does the principle of independent assortment apply to chromosomes? How does meiosis create genetic diversity? How are somatic cells related to genetic inheritance?
When a cell reproduces, the chromosomes (DNA) get copied and distributed to each offspring or daughter cell. Non-sex cells have two copies of each chromosome that get copied and each daughter cell receives two copies (mitosis). Duringmeiosis, precursor cells have two copies of each chromosome...
In What Type of Cells Does Mitosis Occur? Most of the cell division taking place in living organisms happens in somatic (non-reproductive) cells through mitosis. For instance, the human body sheds and replaces up to 40,000 skin cells per day, according to theAmerican Academy of Dermatology....
protects a soldier from enemy fire would be a great asset, but DARPA's not stopping there. This shield would also be able to make the soldier beneath it invisible, and would be self-healing, meaning that if a bullet does manage to get through the shield, the material could repair itself...
Using an example of a familiar plant, describe its life cycle as it alternates between multicellular sporophyte and gametophyte stages. Describe these multicellular stages and explain where fertilization, mitosis, and meiosis occur in the life cycle. Incl ...
This occurs during meiosis, when the X and Y chromosomes separate a bit from the other chromosomes and form an XY body. The Y chromosome gets inactivated by having the X chromosome's inactivation spread over to the Y chromosome. The X chromosome remains inactivated in meiotic spermatocytes, ...
These regions, identical in both sexes, aid chromosome pairing during meiosis and ensure proper segregation. Pseudogene: DNA sequences that once encoded protein sequences, but which are no longer transcribed into messenger RNA (mRNA) in a way that translates to functional protein. Stratum: Region ...
