Biology is classified as a natural science. It's the study of life, basically.

All kinds of living beings have a cell or cells. Biology lets us study the basic cellular structure and how it functions.

Genes determine what you will or won't inherit from your parents - other than money. It's about what dominant and recessive traits you get.

Evolution is about how organisms change and develop. It could be through mutation or natural selection, or also of other combined forms.

Plants can convert light energy into chemical energy through photosynthesis so they can function well. The basic source of that light energy is the sun.

Biochemistry is also important to study, as it involves chemical reactions and how they affect our biology and stuff. Since there are many cells in a given living organism, analyzing chemical reactions is important to intersect with analyzing cellular functions.

Energy of all kinds is found everywhere, in all living beings. We, too, have energy, and we need it to function well.

Our genetic code is inside the DNA. Several scientists worked on discovering different aspects of its existence.

Homeostasis should be maintained by all kinds of living beings. It's all about equilibrium.

Prokaryotic cells are those without a nucleus. Prokaryotic organisms are one-celled organisms.

Eukaryotic cells are those organisms that have more than one cell usually. They can also be called multicellular beings. All of those cells have a nucleus.

Charles Darwin's publication called "On The Origin of Species" shed a lot of light on evolution. He formulated his theory by observing different living organisms in the Galapagos Island.

Botany is a specialization that focuses on studying plants. It's actually a great college course, with a lot of fieldwork and traveling to do experiments and make discoveries.

It was in 1665 when Robert Hooke published his discovery of cells. He was looking closely at corks when he made the discovery.

DNA literally means deoxyribonucleic acid. All living beings have DNA, from humans to bacteria.

The microscope is a wonderful invention to help us look closely at minuscule things nearby. You could say that it's the exact opposite of the telescope, which was invented by Galileo, to look at large objects far from us.

Genetics is the formal study of how genes function and carry information. The scientific people who practice this profession are called geneticists.

DNA has a double helix shape. It looks sort of like a spiral staircase.

Zoology focuses on all kinds of animals, at all of their stages. The people who practice this profession are sometimes referred to as animal scientists.

Gregor Mendel was a botanist whose intensive studies on genetic traits are very useful up to now. He was also a monk under the Augustinian order.

James Watson and Francis Crick were the ones who suggested the double helix model of DNA. But they built upon earlier DNA studies made by Rosalind Franklin and Maurice Wilkins, so credit should be given to them as well.

Chlorophyll is found in green parts of plants. That's what makes photosynthesis happen.

Ecology deals with how we all live within our environments. It's the study of the populations of living organisms in relation to how natural resources are affected by their existence.

The animal kingdom actually has many subcategories. But the two main classifications are vertebrates and invertebrates.

Animals are generally classified according to the existence of a spine, or what we humans refer to as the backbone. Those without one are called invertebrates, while those with spines are vertebrates.

Physiology is about how living organisms function. It also concerns functions of bodily parts.

Warm-blooded animals don't change their body temperature according to the temperature outside their body. So they need to keep warm if it's cold out there.

Cold-blooded animals change their temperature according to the temperature outside of their bodies. Amphibians and reptiles generally belong to this category.

Mendel conducted his experiments using peas. This was his main choice, since the plant has very observable traits, making it easier to study, experiment on and manipulate.

Molecular biologists deal with studying the genetic levels of our existence. This subfield has relevant real-world applications today that help with biological resource conservation efforts.

Atoms join together to form molecules. That is essentially what DNA is - molecules called nucleotides.

The digestive system involves the inner workings of our internal organs, to process the food we eat. It's also covered in biological studies.

The immune system deals with how our human body protects itself from outside harm. Disease prevention is also highlighted in studying anatomy.

Taxonomy is actually about having a formal method of classification. This term applies to labeling and naming all kinds of living organisms, basically.

Ecosystems are either terrestrial or aquatic. But it's interesting to note how some living organisms could survive on either kind of system.
