How a baby born what should we do for become parents? |
|
Answer» Answer: How old are you? Look, kid if you ALREADY KNOW what it takes to give birth to a baby, then don't post such questions. However, if you really don't know how they are born, then I'ma EXPLAIN it to you. Puberty is the age when you are able to reproduce (able to become parents). Humans reproduce sexually, which means that a gamete (such as a sperm or EGG cell) with a single set of chromosomes (haploid) combines with another to produce an organism composed of cells with two sets of chromosomes (diploid). As soon as a sperm cell reaches the ovum, then a zygote is formed. Initially, the zygote matures into a fetus, which further matures into a baby and it is housed inside the mother's womb. Babies come out of the female reproductive system, which is the vagina after 9 months of pregnancy. |

Answer» Answer: Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; FAMILY and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and climate. Continuing in this tradition are current investigations into the roles of pollutants and other aspects of the human-made environment in affecting patterns of human growth and development, specifically the timing of SEXUAL maturation and the development of OBESITY. Some of the methodological problems in CONDUCTING such studies are presented, as are results from an ongoing investigation among one Native American community that show relationships of pollutants to sexual maturation, overweight/obesity and thyroid system function which can IMPACT growth and maturation.
