Biology is the science of life. Whether you're a biology pro or just a biology newbie, knowing the fundamentals is key to having a basic understanding of the world we live in. In this quiz, we're going to test your biology skills. When you succeed, you can finally rejoice that you know where your femur is.
If you did not get this question right, please grab a cup of coffee before continuing. People who study biology are biologists!
Ecology is a subset of biology. It's the study of ecosystems and how organisms live and interact with their environment.
Mushrooms, yeast, and mold are all types of fungi. Fungi have their own unique place and function in the ecosystem.
The body has 12 systems. These are cardiovascular, digestive, endocrine, immune, integumentary, lymphatic, muscular, nervous, reproductive, respiratory, skeletal and urinary.
The cardiovascular system is otherwise known as the circulatory system. It's responsible for transporting blood, oxygen and nutrients.
The endocrine system is responsible for creating hormones which regulate metabolism, growth and development. Hormones also regulate sleep and mood.
Charles Darwin is responsible for the theory of natural selection. This is also called survival of the fittest.
Global warming is largely caused by too much carbon dioxide being released in the atmosphere. This causes the Earth's atmosphere to hold a lot of heat near its surface.
The French chemist and microbiologist Louis Pasteur is responsible for coming up with a process that keeps food from making us sick. This is called pasteurization.
Gene mutation is the alteration of a gene. This mutation leads to a new trait or characteristic.
Antibiotics are used to treat a whole host of bacterial infections in the human body. Antibiotics will not treat the common cold.
Animals that only eat plants are known as herbivores. Animals that eat mostly other animals are called carnivores.
There are four main blood types. These include A, B, AB and O. Which type are you?
The main types of blood protein are albumin, globulin and fibrinogen. Albumin helps to control blood pressure and to carry vitamins and nutrients
Your blood can only have the kind of antigen it currently has. That's why only certain people can donate blood to other people. It has to be a match.
O is the universal donor when it comes to giving blood to others. Anyone can use O blood, and AB folks are universal recipients!
Every healthy person has 23 pairs of chromosomes in every cell of their body. The pairs of chromosomes are found within the nucleus of the cell.
You can actually clone an animal using one of its cells. That's because all the information that you need is found in each cell.
Yes, the Great Barrier Reef is alive! It's also the largest living structure on Earth, so we'd better protect it.
It was in 1674 that a cell was first seen under a microscope. Antonie van Leeuwenhoek was the scientist that did it.
The common cold is a viral infection, not a bacterial infection. That's why it can't be treated with an antibiotic.
Bacteria are single-celled organisms. That means that they're made up of just one cell.
All of these animals are endangered species. If we do not protect them, they will become extinct. They're only three types on a long list.
Not all bacteria is bad! The bacteria that helps you digest food, like that found in yogurt or kimchi, is quite good for you.
Our immune system uses antibodies in order to fight foreign invaders. It also uses microphages, which come from white blood cells, that keep disease from spreading.
Dolly the sheep was the first mammal to be cloned from an adult cell. This took place in 1996.
Traditional wisdom holds that we actually have more non-human than human cells - about ten times more bacteria cells in our bodies than human cells. However, some scientists now say the ratio may be about one-to-one.
In science, a hypothesis is the possible explanation for something. Once a hypothesis is formed, the scientific method is employed to test it.
Enzymes speed up chemical reactions. Enzymes in the body also aid with digestion.
Abiotic factors in our environment are those that are nonliving. A rock, for instance, is an abiotic factor.
An organism's habitat is the place in which it lives. Each organism has a niche function within its environment.
Predators are animals that go on the hunt for their prey. A lion, for instance, might go after a deer.
A climax community occurs when an ecosystem has reached its capacity for growth. When a city reaches its maximum capacity, people just build taller buildings!
The circadian rhythm is based on a 24-hour cycle. Your circadian rhythm will dictate your sleeping and waking schedule.
Cell walls are actually only found in the plant community. They add layers of protection to the plant cells.
