by hi Member since:December 26, 2009Total points:4,388 (Level 4)To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex. men and women have similar tissues and body parts. If anything the embryo follows a 'female template'. That is why nipples are present in both sexes. It is the effect of the genes, the Y chromosome and the hormone testosterone that brings about the changes and masculinises the embryo. Testosterone promotes the growth of the penis and testicles. Because nipples are there before this process begins the nipples stay!

Member since:March 01, 2011Total points:564 (Level 2)For the first 2 months after conception, all fetus's are the same, male/female. Its only after that that they develop their x/x or x/y chromosomes. (x=female, y=male). So because everybody has an "x" chromosome, males and females share some parts, i.e; nipples. by Chris Member since:July 30, 2008Total points:397 (Level 2)Men have an X and a Y chromosome. They have nipples because of their x chromosome. They are unable to produce milk like females because of their Y chromosome. Females have 2 X chromosomes and no Y chromosomes, so they are able to produce milk.Imagine a guy without nipples. It would look really weird.

Open Question: Was there a spirit in my house?
Starfire Member since:June 28, 2008Total points:3,338 (Level 4)The night before my graduation my brother had a friend over. When my brother went in his room to get his blanket there was this big black figure acrossed his bed. There was nothing that could of made a shadow like that in his room. Then when my brother and his friend were about to fall asleep downstairs the lap turned on all by itself. After that they heard footsteps going up the stairs. No one in my house was walking around at that time. I am starting to think that it was my grandpa who passed away back in September because there is no history of anybody who died in my house. Are there any explanations for this? If so, can you tell me what they are? Thanks!Answer Question by Lala Lala Member since:June 06, 2011Total points:102 (Level 1)shadowww!!!!!! dont worry mijo its okayyyyy(:

Open Question: smallest distance between two planes in space?
In that case use the distance formaul d = sqrt( f(x)^2 + g(x)^2) where d is the distance, then find the derivatives which will give u the maximum distance (if there is one) and the minimum, this minimum value is the smallest distance.
Open Question: Name two reasons why this ecosystem would have a low rate of speciation...?
organisms can easily leave or enter the ecosystem - immigration provides a steady gene flow from outside of the ecosystem which easily flows throughout because of the lack of barriers.
These create a system that has high rates of gene flow in and out as well as throughout. These properties are not conducive to speciation because genetic isoloation (whether reproductive or ecological) is what causes speciation events.
