Muations 1/15

Image result for mutation gene




Summary:

A mutation is a change in genetic material, nucleic acids to be exact. Both internal and external factors can cause mutations. An example of and external factor would be smoking, or exposure to UV rays. An internal factor would be a mess while DNA was replicating. Mutations are completely random. The result can be helpful, harmful, or neutral. Gene mutations can be cause by insertion, substitution, or deletion. Substitution is when there is a wrong base match. Insertion is when a base is added. Deletion is when a base is deleted. Insertion and deletion are much more dangerous that a substitution. Chromosome mutations include duplication, deletion, inversion, and translocation. Duplication is when there are extra copies of chromosomes. Deletion is when a piece of chromosome breaks off. Inversion is when a chromosome is reversed or flipped. Translocation is when a piece of chromosome breaks off and attaches to another chromosome.

S&EP-Using Models:
After completing a scenario sheet, we drew our superhero child as an adult. This was a very interesting activity as many possibilities may happen. My superhero's child was completely healthy. He was at risk for two different scenarios which meant that it could or could not happen. Upon flipping the coin to see if he would take the healthy option or diseased, it ended up that my superhero offspring was healthy. My other classmates superhero children was much different than mine. One of my classmates drawing was the offspring in a hospital bed and hair loss, while another had five different diseases. There was everything from completely healthy to almost dead. Drawing out the effects instead of reading about them really shows how the effects affect your body.


XCC-Cause And Effect:
Even though the DNA you receive from your parents makes you who you are other things such as what the mother does when she's expecting and what you do when growing can influence how you turn out to be. We went through many scenarios including diet, exercise, amount of sleep and more to see the result. After completing that task we had to flip a coin three times. If it landed on tails zero to one times the child would have the healthier option, if the coin landed on tails twice the child would be at risk of the unhealthy option and if it landed on tails three times the child would definitely have the unhealthy option. We used this information and created an drawing of our superhero as an adult. It was interesting to see how different some drawings looked just because of some small decisions.

Amedeo Avogadro - 5/27/18

Image
Summary : Amedeo Avogadro was an Italian scientist who created what is now known as Avogadro's law. Known as a founder of the atomic-molecular theory, he was the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms. His biggest contribution to science, Avogadro’s law, states that equal volumes of gasses under the same conditions of pressure and temperature will contain an equal number of molecules. Amedeo Avogadro was born on August 9th 1776 to Filippo Avogadro and Anna Maria Vercellone. Coming from a family of lawyers, Advogadro was guided to a legal career, and became a bachelor of jurisprudence in 1792. Despite a successful legal career; Avogadro has started private studies of mathematics and physics, which then he pursued full time. SP8 - Communicating Information : This week, I communicated information in the form of a wanted poster about a certain scientist. I decided to create a wanted poster about Am...

Roller Coaster Project Blog - 2/18/18

Summary : A roller coaster ride is a thrilling experience which involves a lot of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor which exerts a force on the train of cars to lift the train to the top of a vary tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. At the top of the hill, the cars possess a large amount of potential energy. Potential energy is dependent upon the mass of the object and the height of the object. As the cars descend the first drop they lose much of this potential energy in accord with their loss of height. The cars subsequently gain kinetic energy. Kinetic energy is dependent upon the mass of the object and the speed of the object. Therefore, their original potential energy is transformed into kinetic energy. Backward-Looking:  How much did you know about the subject befor...

The Designer Species Project - Project Blog 11/5/17

Summary: The Fobra is a new species of frog with the body of a red-eyed tree frog, the eyes of an owl, the fangs of a king cobra, and the claws of a squirrel. Since the fobra lives in planet C, a tropical planet with much rainforest and vegetation, our frog can "nest" itself in the plants to stay warm. To stay cool the fobra can soak itself in puddles and absorb the moisture. The fobra is also a warm-blooded animal. The fobra uses both its tongue and teeth to eat, depending on the size of animal it is eating. With the claws similar to squirrels, the fobra will be able to get away and climb up on trees faster, making predators unable to get it. As well having the bite similar to the king cobra, our species will bite predators when it feels threatened or scared by predators that are after them. The fobra will be able to strike extremely quickly, like a cobra, in self-defense. Red-eyed tree frogs will lay clutches of eggs on the underside of leaves that are standing abo...
