development in the womb. The developing embryo will go through many changes. From the development of organs and bones to eyes, ears, and tiny feet and hands, what once was an egg and sperm will become a child. Fertilization A sperm must locate the mature egg in the fallopian tube. Once the sperm fertilizes the egg, the egg, which is now a blastocyst, will continue to move down the fallopian tube into the uterus. On or about the seventh day, the blastocyst develops chorionic villi, hairlike structures

For this assignment, I chose the disparity of proper healthcare provided to the LGBT+ community. Those who identify with the LGBT+ community includes gays, lesbians, bisexuals, transgenders and many other sexual orientations and gender identities. Those who are part of this community has, historically, faced discrimination in the healthcare profession, and therefore has caused many individuals to shy away from seeking proper medical treatment for fear of discrimination. With the fear of discrimination

What is genetic variation? Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces. * Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. * Genetic variation is a result of subtle differences in our DNA?. * Single nucleotide polymorphisms

humans. From females of older age, with poor egg quality, and severe endometriosis. More factors that lessen chances of success is poor sperm quality or severe damage to fallopian tubes. Females with "unreceptive cervical mucus" are also good candidates for artificial insemination. In these females, the mucus surrounding the cervix is hostile to sperm and prevents sperm from getting into the uterus and fallopian tubes. Artificial insemination allows the sperm to skip the cervical mucus entirely. Doctors

plants experience alternation of generations. Two distinct phases exist: A diploid sporophyte alternates with a haploid gametophyte. (In reality these phases represent two body forms of the same organism). The gametophyte produces gametes (eggs and/or sperm). A diploid sporophyte produces spores by meiosis. Sporophytes and gametophytes look distinctly different from one another (heteromorphic). Mosses and Ferns Phylum Hepatophyta (Liverworts) The plants are called liverworts because they

Introduction Prenatal development refers to a series of development stages that begins from the fertilization of the egg by the sperm cell to the onset of birth process. It begins with the formation of the zygote to the development of the fetus. It involves three major stages namely, germinal stage, embryonic stage and fetal stage. (Balinsky, 1975) The developmental stages take place partly in the fallopian tube and in the uterus. It usually takes a period of nine month in human being but varies

IVF begins with fertility medication, that is prescribed to stimulate maturation of oocytes and hence production of eggs. This is required as unfortunately some eggs will not fertilize or even develop, this is viewed by some as wasting the eggs and hence human life and is the reason why this step is so controversial. For example ´controversy surrounding the birth of Louise Brown in July 1978, together with lack of funding, brought

legs and feet were better adapted to get around in such environments. Aquatic plants, such as fern reproduce by having the sperm swim to another plant, plants became dependent on water in order to produce offspring. In order for this to be achieved, the eggs of the female had to be closer to the ground to enable the sperm to not have to swim as far. As plants evolved, their eggs became found on the top of the

different ways. Its progestin thickens the mucus on the patients’ cervix, which prohibits the sperm from swimming through to the egg. If the sperm cannot reach the egg, pregnancy cannot happen. The other way the implant prevents pregnancy is by ovulation. Ovulation is when progestin stops the eggs from leaving the patients ovaries. When the eggs are not realized from the ovaries, there is no way it can reach a sperm therefor the patient cannot become pregnant. Nexplanon also changes the lining of the patient’s
