Algae and moss are two types of organisms that are often studied in biology. While they are both classified as non-vascular plants, there are several significant differences between the two. What are Algae? Algae are unicellular or multicellular organisms that belong to the kingdom Protista. They are found in aquatic environments such as oceans, lakes, and ponds. Some species of algae can also be found in soil and on moist surfaces such as rocks and trees. Algae can be classified into three main groups based on their pigmentation: red algae, green algae, and brown algae. Red algae are found in ... Read More

With the unification of trade worldwide and the advancement in science, units of measure changed from traditional ones. This has enhanced common understanding of terms used universally in trade, education and many other aspects of life, as well as eradicating inconsistencies. Examples of these units of measure are grams and kilograms. What is Gram? This is a metric system used to refer to mass. It was adopted in the year 1795 by the French National Convention and replaced the gravet. It is used widely in the measurement of ingredients that are not liquid, such as cooking materials. The official symbol ... Read More

Exponential growth and exponential decay are two fundamental concepts in mathematics and science that describe how a quantity changes over time. Both exponential growth and decay follow a mathematical model that is characterized by a constant rate of change, but they are fundamentally different in terms of how the quantity changes over time. What is Exponential Growth? Exponential growth refers to a situation where the quantity of interest increases at an exponential rate over time. This means that the rate of increase of the quantity is proportional to the current value of the quantity. In other words, the more the ... Read More

In contrast to metaphysics, which is concerned with what comes "after physics” (the Greek word "metaphysika"), epistemology (from the Greek "episteme, " meaning "knowledge, " and the suffix "ology, " meaning "the science of, " or "the study of") is concerned with the study of the extent to which knowledge and justified belief are possible. Metaphysics seeks to gain a complete understanding of the nature of reality, including abstract concepts (identity, time, space, being, knowing), while epistemology examines how we know what the actual reality or truth is and whether there are limits to this knowledge specifically in terms of ...

Since ancient times, we have known that fear is an evolutionary instinct. It is instrumental in keeping us safe from anything that might harm us, from alligators in the swamps to other people who might try and rob or murder us. The fear response system primarily involves the amygdala - a brain region controlling an individual's emotional responses. This part of our brain reacts quickly when we sense danger around us. The amygdala helps us to do this by sending signals to the rest of the brain, causing a "fight or flight" response which causes the release of adrenaline into ... Read More
