The correct answer would be the second option. The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical dysplasia. It is a pre-cancerous condition that involves an abnormal growth of cells in the lining of the endocervical canal which is the opening between the vagina and the uterus. A very common cause of developing this is the virus HPV or the human papillomavirus. It can be transmitted sexually and has many strains. This condition can still be cured when it is detected early. Without treating it, cervical dysplasia would develop to cancer.<span />
A cladogram is a branching diagram that shows the cladistic relationship between a number species. It comes from the greek clados meaning branch and gramma meaning character. It is not to be confused with an evolutionary tree since it does not show the relationship between ancestors and descendants plus it also lacks the ability to show how they have changed over time. The major components of a cladogram are the tip (the start of the lineage), root (the end of the lineage) and node (where two or more lineages combine).
Answer:
Sperm-egg interaction
Explanation:
The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.
The answer is 'Genes and Chromosomes'...
