An example of an observation is seeing a person walking a dog on the sidewalk. One inference I can come up with about what I had observed is that the person walking the dog is the dog's owner. Another inference I could make is that the person is walking the dog on the sidewalk to avoid danger to both the dog and themselves.
In the 19th century new ideas had emerged of how the brain functions. There were two different theories at the forefront during this period. Camilo Golgi, best known for creating the Golgi stain, had theorized that the brain was circulatory network such as the heart and that neurites of different neurons were all connected. Another scientist Santiago Ramon y Cajal believed that the brain worked via contact rather than connection. He theorized that neurites of different neurons are not continuous with each other and communicate by contact. The theory that was proposed by Ramon y Cajal would be known as the Neuron Doctrine. However, his theory was not accepted until proven much later by the electron microscope, and is now universally accepted
I went to the Morrill Greenhouses from 12pm-1pm. I entered into the second collection house. I gazed through the flowers until one flower caught my eye. The flower was the Hibiscus rosa-sinensis Malvaceae. I decided to photograph the flower in front. The first photograph I took was of the flower with some of the leaves. This photo was obtained by have the camera at a diagonal angle to get enough detail of the leaves and flower. The next photograph I took was of the flower up close. I took this photo at an slightly less than parallel to the flower in order to get the best detail. I took two more photos with a coin in order to show the relative size, one photo was of the whole plant with a quarter, and the second one was of the flower with a coin in view. By using a collage maker from the internet I created one figure. In the figure I also put a map with filled in countries of where the flower originated.
My goal of obtaining a flower was to find the flower that stood out to me most. I planned to obtain the photo during mid-day because the sun would be able to shine on the flowers. I wanted to go the Morrill Greenhouses since I pass by them almost every day. The flower that accomplished the goal is the Hibiscus rosa-sinensis Malvaceae, commonly known as the “Snow Queen.” The vibrant color of a dark pink almost red stood out to me, so I decided to use this flower for my figure. These photos were taken at different angles in order to get the full plant and then a very detail picture of the flower itself. In order to create a follow view of the flower, I used several photos including two with an object to show perspective of how big the flower actually is. After taking the photos, I will label each and include another figure of a map of where the flower originates.

Autopolyploidy causes the offspring to be reproductively isolated from its parent species. After the formation of the tetraploid offspring the gametes that they would form would be 2n of 6 chromosomes. The parent species forms gametes with n of 3 chromosomes. The parent species and offspring species can produce an offspring with 3n, although they would be sterile because gametes would not be able to form since a chromosome would be left unmatched during meiosis. This is an example of post-zygotic reproductive isolation because the offspring would be sterile but would have been viable.
Using Bloom’s taxonomy from Lesson 1, I believe that on the pyramid this question would be apply. I believe this because you are taking information we have been given and applying it to the question. In this problem you have been given beforehand which amino acids have been in each category, although, in this problem we are not asked to determine the amino acid shown in the picture, but to determine the category of the picture and then pick one of the listed that is also in the correct category. In order to answer the question correctly, demonstrate your knowledge of the classifications of amino acids.
Defensin genes in snakes are expressed in the pancreas and are used to fight infections, in humans, pigs and mice they are also used to fight infections. Gene is the process of generating new genetic material by copying the gene sequence. Regulatory mutations are presences of enhancer or silencers in a region of DNA that can control transcription. Coding sequence mutations are changes in the DNA sequence which leads to different proteins being synthesized. These three mechanisms helped evolve defensin genes into venomous crotamine. Gene duplication helped evolve crotamine by creating copied of defensin genes to attack different pathogens. A regulatory mutation which changed where a protein was produced was duplicated in snakes, the new protein location allowed snakes to release the defensing into the bite wounds of the prey. More mutations of the duplicated gene caused for the evolving of the defensin from attacking pathogens to attacking the prey’s muscles. Different venoms evolved from different genes from either the heart or brain. These genes went through regulatory mutations that were duplicated over and over. More mutations fine-tuned them into the venoms today. Venom genes were seen to be in a common ancestor of all snakes.
Figure 1: C. lupus familiaris skull.
The figure illustrates the structure of common dog’s skull. The skull is two separate parts connected by the mandibular condyle fits into the mandibular fossa. The lateral view of the dog skull shows the different bones that have fused to become whole
The flower I photographed was the Hibiscus rosa-sinensis Malvaceae, commonly known as the “Snow Queen.” This flower is commonly found in Asia such as China. The flower is edible and can be found in salads, along with other uses such as hair care. The flower can be a pH indicator, in acidic solutions the flower turns a deep purple and in basic solutions the flower changes to green. In China, the flower is used for medicine and skin care. The flower is grown in tropics or subtropics because it cannot survive in temperatures below 10oC (50oF).
