The CER method is applied to a statement that can be supported with data and explained why. This method can be used when dealing with the news to ensure that the information we are receiving is accurate. When the news introduces a claim, one has to make sure that the claim is supported by evidence and that its reasoning can be explained. The "Claim, Evdence, Reasoning" method is also seen in the news as it helps people organize their statments and provide reliable evidence. This evidence must be found through unbiased and peer reviewed outlets to ensure its most accuracy. The "CER" method can also be applied to biology as it is a foundation in building a strong argument. The "CER" method and the Scientific method are two similar and crucial formats in the science community. Scientists must always follow them to ensure they have enough evidence and reasoning to have a claim accepted. ]]> 2023-01-25 14:28:48 UTC https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2456213453 About me ashleyrivera017 https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2456214033 Good Morning, my name is Ashley Rivera and I am from Venezuela and Honduras but was born and raised in Hollywood, Florida. I currently attend MDC Kendall campus and am studying psychology. I work as a personal assistant for a real estate broker and also work as a hostess at Pani Aventura. I love to travel and success to me means being able to see the world and explore new cultures. I am very passionate about cars and love anything to do with them. I enjoy working on my engine and drifting safely. I love going to car races and shows and meeting new people with the same interest. During my free time, I normally try to catch up on rest since I am always on a tight schedule. I also love to go shopping and go on random adventures with my friends. One of my greatest strengths is how easily I can connect with others of all cultures and backgrounds. In the future, I see myself traveling with my family and helping others around the world. ]]> 2023-01-25 14:29:14 UTC https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2456214033 The Orca ashleyrivera017 https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2459026158 The Orca also know as the Oricinus Orca roams in our Ocean primarily in the cooler regions. The orca is a toothed whale that is part of the dolphin family. Orcas are normally black and white and they vary in size from 20 to 26 feet in length. The Orca has a lifespan of almost 90 years and females seem to have a longer lifespan.

It travels very easily from person to person & is highly contagious. I found it interesting how the cold can be easily caught not just person to person but by touching something that came into contact with someone with the virus. It is very important to wash your hands frequently and avoid coughing into the air.]]> 2023-02-06 14:22:27 UTC https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2470142462 Feedback Loops ashleyrivera017 https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2476518795 Question: Describe an economic or social or political example of positive feedback.

An example of a social positive feedback loop is the self fulfillling propechy which is when enough people believe that something is true, ones behavior adjusts making it true. If multiple people make one thing seem realtistic, more people will believe it resulting in a truth.

It travels through coastal, coolers waters such as near Antartica and Alaska. Although they prefer coolder waster, they sometimes travel to warmer regions such as in the Gulf of Mexico and near Australia.  They tend to feed off a range of fish such as Salmon, Cod and even seals and dolphins.

All cells need ribosome's to make the necessary life proteins. They are made inside the nucleolus of the nucleus. Some ribosomes are attached to the endoplasmic reticulum, others float freely within the cytoplasm.

These high pollutant levels weakens their immune system and affects reproduction. Warmer temperatures also lead to less sea ice causing the whales to swim further north in search for food and cooler temperatures. Climate change also takes a great toll on limiting access to their preferred prey, Salmon. Climate change affects ocean conditions leading to changes in salmon growth and migration patterns reducing the ability to find food. Climate change leads to a rippling effect on ocean animals.

Although that is the REAL reason, I do like Orcas and find them interesting. I love the all black color with white areas they have and how it always looks like they are smiling. They are such big, smart animals with so many capacities. This animal is impacted by climate change as warmer ocean temperatures causes a ripple effect in their ecosystem. There is less fish for them to feed on leading to them having to migrate to areas that aren't good for them. Warmer temperatures also increase pollutant levels in the water.

She choose a tree-jungle like background which I find so appealing as it matches the "biology" vibe. I also love the way everything is organize and easy to read. She distributed her information very evenly and all her paragraphs are clear and informing.  I also love the species she choose as I find monkeys so cute. I find it interesting that there are less than 250 of them left and that they are only found in Peru. I loved Melanie's padlet!

Over 250 Million years ago, Orcas were a single homogenous species and they are now distinctly different ecotypes. There are at least ten different ecotypes which each have different "languages", cultures and lifestyles. This diversification took between 5000 to 9000 generations to happen. There are so many variations from small fish eating whales in Antarctic to large whale eating ones in the North Atlantic. Orcas have a thick layer of blubber for warmth as they live closer to the poles and they can swim very fast to catch prey. They use echolocation to locate and have sharp teeth to chew their prey. Orcas have a unique black and white pattern as a form of camouflage. They are light colored on the underside and dark on top so they are less visible from both above and below.

It talks about how the brain has everything to with love including the happiness and heartbreak. When you begin to fall in love with someone you go through the first phase which is infatuation where you want to always spend time with that person. There is increased activation in the ventral tegmental area which is the reward-processing and motivated part of your brain. When it is activated, dopamine is released. Love influences a haze where you can't see the bad in a person as it decreases the cognitive ability of the pre-frontal cortex. The second stage is attachment in which you feel more trusting and commited due to two pair-bonding hormones called oxytocin and vasopressin. They signal trust and social support so it causes you to bond with people and feel calm around them as these hormones inhibit stress. Regardless on why a relationship ends, the distress of a breakup activates the insular cortex which processes pain (physical and social).  ]]> 2023-04-17 03:48:23 UTC https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2556325936 Essay ashleyrivera017 https://padlet.com/ashleyrivera22/ffeds0in3m32o38a/wish/2559513019 Science has always been one of my favorite subjects, especially Biology. I remember my first and last Biology class that I took which was 5 years ago. It was a high school level course that I took in middle school in which I fell in love with the subject. I found it so interesting how biology is associated with so much of nature. After 5 years of not expericiencing one of my favorite subjects, I was finally able to take it again this semester except this time online.
To begin with, when I first started this class I was quite nervous as I had never taken an online biology class. I was really excited to take biology but if I'm being honest, I wasn't looking forward to taking it online at all. I expected that I will be loaded with homework and will not be able to learn much in class as online teaching is very different than in person. 
However, when I started the course, I realized the class was not as difficult as I imagined. All our assignments are done in class which I greatly appreciate. I really enjoyed doing class activities such as poll quizzes, watching videos, and writing discussions. I also really enjoyed having padlet as it was an easy way to keep track of all of my asssignments. Being able to work through the entire duration of the semester with the same animal but new information on it also made it easier to comprehend lessons.
In conclusion, this class reassured my love for science. I loved doing research on the species of my choice and the various activities done in class. I also learnt alot from this class including making a padlet and presenting it. Science is one of my favorite subjects and that doesn't change whether the class is online or not.
