Plan B Post 1 - January 1, 2013

Did you have unprotected sex last night? There is still a chance for you to not get pregnant if that was your ovulation day and you have up to 3-5 whole days to swallow this pill because sperm can live and wait for the egg for up to 5 days, but best results are when taken in the first 24 hours. I'm sorry for all the youngsters age 17 years and younger as the only way for you to get this drug is by prescription while it's over the counter for everyone else. This pill delays the ovulation process or prevents fertilization of the egg. Once implantation has occurred, there is no stopping this pregnancy as levonorgestrel, the drug known as plan, the "morning-after" pill or emergency contraception, is not a method of abortion, nor will it protect you from and STIs. Stick to safe sex.

This video explains in much more detail and in some humorous ways how the pill works to prevent pregnancy. It shows how ovulation works and how this plan b pill it from happening. It also shows how it traps the sperm from being able to reach the egg. This video breaks it down so anyone with a slight biology knowledge can understand how this pill works which is good to include in this post. The first imageis the formula of levonorgestrel. As shown, it is made up of carbon, hydrogen and oxygen. The second is the progesterone which is also made up of carbon, hydrogen and oxygen. This pill (the first image) is a synthetic version of the natural hormone progesterone ( the second image). Their structural formulas are nearly identical and the only difference in the chemical formula is that progesterone has two more hydrogens. Levonorgestrel - C₂₁H₂₈0₂, Progesterone C₂₁H₃₀0₂. To learn more about either of these click on their image to visit their site.



This image can help a person to better understand the fertilization to implantation process that occurs in a female reproductive system. The "morning-after" pill prevents number 2 from happening which will in turn prevent number 1 from happening. For a description of how it works click the image to go to the site.

These two images are both from the same site which hold a lot of methods of contraception. They take a comical approach for he pictures, but a serious one in the information. The first image is of an egg preventing the sperm from getting it by comparing it to a bullfighting as in you can try and get me but you won't. The second image is emergency contraception where something must happen quickly to prevent the sperm from getting to the egg; in this case a bomb would clear out all the sperm like in real life with people.

Safety This site is an article with a question and answer of the safety of this drug and how it may affect a developing fetus, cause abortion, etc.

Effectiveness By clicking the link above you will be taken to a website with an FAQ of mostly how effective this contraception pill is.

Side Effects Before taking anything one should be aware of the side effects and this is exactly where this site will take you.

<span style="font-family: 'Comic Sans MS',cursive;">Imagine if our eyes could not see things or people or colors or shapes, but only light and dark. If when we were born all we could see was movement, but not real movement like if someone put their hand in front of your face, but just different shades of light and dark so you perceive that as movement. The world would be much a much different place. Researchers believe that eyes could see just that, nothing but light and dark before natural selection started to occur like Darwin said and only those that had unusual traits at that time survived, so that after very many years we are born with these complex eyes that let us see those things, people, colors and shapes. Some organisms were not as lucky and do not get to see the way we do though as they are stuck with those shades of dark and light and others find themselves in the middle with blurred vision, but some are even more complex then ours and can see more then us. The link below will take you to a site with a slide show of 17 different organisms and explains how each one sees.

<span style="font-family: 'Comic Sans MS',cursive;">[|Different Eyes]

<span style="font-family: 'Comic Sans MS',cursive;">This next video will explain the different layers that were added and changed to create the eyes that we see today. media type="youtube" key="lEKyqIJkuDQ" height="315" width="420" align="center"

<span style="font-family: 'Comic Sans MS',cursive;">It is believed that organisms started out with a flat line that could sense dark and light, but would not know which direction it was coming from. If made into a cup form is gets a better sense of direction if the angle of light is great enough. The more cupped it gets the better sense of direction is received, also because the point where light is getting in is smaller, making the image sharper because less cells are being touched by the light. As they continue, a hardened mucus is added and a few lenses to sharpen the image some more creating a detailed view of the surroundings.

<span style="font-family: 'Comic Sans MS',cursive;">The next video is similar to the one before, but with more detail as to what the eye is made up of for us the see images the way organisms do. They also have a model made out of lenses and other materials to demonstrate this.

<span style="font-family: 'Comic Sans MS',cursive;">The image above is of 121 different human and animal eyes. Some are very similar and some are very different, but almost all of them see differently from one another. The image below is of five different animals with very differently shaped eyes.

<span style="font-family: 'Comic Sans MS',cursive;">As explained above about how eyes once started out as flat lines of cells, this is a picture diagram of each stage.

<span style="font-family: 'Comic Sans MS',cursive;">The image above is of an eye with labels so we can see where everything is located in the eye. To the right of the image is a blown up version of the retina which is made up of different cells, rods and cones. <span style="font-family: 'Comic Sans MS',cursive;">Above is the mantis shrimp, which is neither a mantis nor a shrimp, but looks like both. They have the most complex eyes to date. As humans, we can see in three colors, but the mantis shrimp can see in twelve. In the future we may rind another organism with a more complex vision, but for now this little crustacean is it. To read more on the mantis shrimp click on the link. Mantis Shrimp

<span style="font-family: 'Comic Sans MS',cursive;">These are all very complex eyes, but some organisms still do have simple eyes and if you wish to learn more about them please visit this website. [|Simple Eyes]

<span style="font-family: 'Comic Sans MS',cursive;">Are you part of a family where you are the only one with a certain color of hair? Are you the lone ginger in a family of blondes of brunettes? Have you always wondered if you were adopted because of this? Although you could be adopted, that's is probably not the case. It seems you have been dealt the gene hand. There is not one gene that decides you hair color, meaning if your mom has blonde hair and your dad has brown hair then whichever of those genes gets given to you will be your hair color. There is actually many genes that are the deciding factor, but it is not whichever is dominant and recessive in the genes either. Through much research I have found that your hair color is determined mostly by the amount of eumelanin genes that are on. If your hair has a lot of eumelanin genes on then it will be black and very little eumelanin genes on will result in blonde hair. If your mom has dark brown hair she will be passing down a lot more eumelanin genes that are turned on. If your dad has blonde hair then he will be passing down more of the genes that are shut off. Together they can create children with dark hair, if they get a lot of those genes from the mom; blonde they come from the dad or a dirty blonde if they get both groups of genes. To get a child with red hair the gene phomelanin must be present and then eumelanin will determine the darkness or lightness of the hair.

The image below is a family with three children and all have different hair color as shown.
