The Origin of Life on Earth

Image
                                At one point in life, it is quite plausible that one has pondered about the origin of life. However, it isn’t as likely that they have utilized the inquiry process and chased after their curiosity. How did organisms suddenly emerge on Earth 3.5 billion years ago (Choi, 2017) and how did the basic single-celled organisms evolve into complex life forms about 600 million years ago? This research report contains thorough explanations of selected scientifically-backed theories, as well as visual aids to further elaborate, for those who haven’t researched this. The origin of life on Earth isn’t confirmed, but many theories have been made, and this research will include the more plausible ones: the lightning strike theory, panspermia, the theory of special creation, the theory of primordial soup, and the hydrothermal vent theory. The first theory is the lightning strike theory. This ...

Factors of Canadian Confederation

Image
Introduction The Canadian Confederation took place in 1867. Before the confederation, there were six main factors that gradually resulted in confederation. In this presentation, we will be talking about the railway issue, changes in British attitudes, American invasion, political deadlock, and   cancellation of the Reciprocity Treaty. We hope you enjoy it! Railway Issue Two people involved with this factor include George-Etienne Cartier from Canada East and Alexander Galt. They had ties with railway companies but were disappointed to see that the Grand Trunk Railway (which linked Toronto and Montréal) was not doing well financially, due to the lack of passengers and freight traffic within the Canadas. Additionally, the Baring Brothers thought of the idea that Confederation would solve the issue and food producers (in the Maritimes) and manufacturers (in the Canadas) believed that the trade that the railways would bring would benefit them.  Before Confederation, the main s...

Why Does Ice Float on Water?

Image
Why Does Ice Float on Water? Have you ever wondered why ice is always floating on top of the water? You would think, water is a liquid and ice is a solid, since solids contract while cooling, their volumes increase, and the density would decrease. Thus, denser objects like ice would sink in water. But it doesn’t! When the water is 35 degrees celsius, the water molecules are moving freely and running past each other. When the temperature drops to 4 degrees celsius, as mentioned in the particle theory, temperature affects the speed of the particles. The water molecules will move and run less. At this point, they are taking less space. If the temperature continues to drop, you might think that molecules will be closely packed together, which means decreasing volume and increasing density. But it is NOT what happens. Water behaves abnormally when it is cooled due to its unique molecular structure. Water has a special interaction between molecules, which is called a hydrogen bond. As we all...

The Functions of Ophiocordyceps unilateralis: a Scientific Article

Image
The Functions of Ophiocordyceps unilateralis: a Scientific Article *do not copy or it will count as plagiarism* Ophiocordyceps unilateralis is just as complicated as it sounds! It's an insect-pathogenic fungal parasite that infects and manipulates ants, and it's also known as zombie ant fungus. Ophiocordyceps unilateralis is found in tropical forests and in many moist places where it can thrive safely. It is one of the many species of Cordyceps, which is a genus full of manipulating fungi, which each infects a different insect. In this case, ants are the victim.  To summarize the process, active Ophiocordyceps unilateralis spores infect ants and force the ants to climb onto the stem of a leaf and bite it with an extreme force so that it wouldn't fall off. Then, the ant dies and a stroma - the main fungus stem - erupts from the back of the ant's head and releases more spores. Although not confirmed, many researchers (like Charissa de Bekker) say that the mind control is ...

LCM: ladder method

Image
 LCM Passion4studying.blogspot.com In this article, we will be discussing what LCMs are and what the ladder method is. LCM In order to know how to add and subtract fractions, we need to know what LCM means. LCM stands for "least common multiple", and it's the smallest multiple two numbers share. For example, the LCM of 12 and 24 is 24, since 24 is a multiple of both numbers, and it's the smallest out of all the common multiples both numbers share, such as 48 and 72. Now, let's discuss the ladder method, which is used to find LCM The ladder To use the ladder method, we must first make an L shape and put our numbers in the L (make sure there's space between them), like this: Then, we must put a factor of both of these numbers on the left of the L, as shown below: Next, we will divide our numbers by the factor they both share, and put the result below the L., like so: And then we continue on and on until we can't divide any further, like above. When we can...

Domestic Abuse and Its Impact on the Prepetrator, Victim, and Bystander & Supporting Services

Domestic Abuse and Its Impact on the Perpetrator, Victim, and Bystander & Supporting Services Physical violence  Physical violence is the type of violence that involves physical contact and attempting to cause pain and injury. In the following sections, we will focus on domestic physical violence - hitting.  Impact of the violence on the perpetrator If the physical violence happens in an abusive relationship or domestic violence, the attempt of the perpetrator is to gain total control of the victim. The perpetrators might constantly accuse the victims of being unfaithful, or never care about the perpetrators, as sometimes the perpetrators might have low self-esteem. They also keep on track of the victim, or sometimes even control all the money the victims spend; so once the victims do something against these restricts, for example, trying to run away, the perpetrators will get angry and irritated and harm the victim. They often feel released after a series of hittings, kic...
