Biology, the study of life, can be fascinating and wondrous. However, certain biology topics can sometimes seem incomprehensible. The best way to get a clear understanding of difficult biology concepts is to study them at home, as well as at school. Students should use quality biology homework help resources when studying. Below are some good resources and information to help you answer some of your biology homework questions.

Biology Homework Help Resources

Anatomy of the Heart
Learn about this amazing organ that supplies blood to the entire body.

Animal Tissues
Information on the structure and function of animal tissue types.

Bio-Word Dissections
Learn how to "dissect" difficult biology words so that they are easy to understand.

Brain Basics
The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ has a wide range of responsibilities.

Characteristics of Life
What are the basic characteristics of life?

Organ Systems
The human body is made up of several organ systems that work together as one unit. Learn about these systems and how they work together.

The Magic of Photosynthesis
Photosynthesis is a process in which light energy is used to produce sugar and other organic compounds.


Eukaryotic and Prokaryotic Cells
Take a journey into the cell to find out about the cell structure and classification of both prokaryotic cells and eukaryotic cells.

Cellular Respiration
Cellular respiration is the process by which cells harvest the energy stored in food.

Differences Between Plant and Animal Cells
Plant and animal cells are similar in that both are eukaryotic cells. However, there are several important differences between these two cell types.

Prokaryotic Cells
Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth.

Prokaryotes include bacteria and archaeans.

8 Different Types of Body Cells
The body contains trillions of cells that come in varying shapes and sizes. Explore some of the different types of cells in the body.

7 Differences Between Mitosis and Meiosis
Cells divide either through the process of mitosis or meiosis. Sex cells are produced through meiosis, while all other body cell types are produced through mitosis.

DNA Processes

Steps of DNA Replication
DNA replication is the process of copying the DNA within our cells. This process involves RNA and several enzymes, including DNA polymerase and primase.

How Does DNA Transcription Work?
DNA transcription is a process that involves the transcribing of genetic information from DNA to RNA. Genes are transcribed in order to produce proteins.

Translation and Protein Synthesis
Protein synthesis is accomplished through a process called translation. In translation, RNA and ribosomes work together to produce proteins.


Genetics Guide
Genetics is the study of inheritance or heredity. This guide helps you to understand basic genetics principles.

Why We Look Like Our Parents
Have you ever wondered why you have the same eye color as your parent? Traits are inherited by the transmission of genes from parents to their young.

What Is Polygenic Inheritance?
Polygenic inheritance is the inheritance of traits such as skin color, eye color and hair color, that are determined by more than one gene.

How Gene Mutation Occurs
A gene mutation is any change that occurs in the DNA. These changes can be beneficial to, have some effect on, or be seriously detrimental to an organism.

What Traits Are Determined by Your Sex Chromosomes?
Sex-linked traits originate from genes found on sex chromosomes. Hemophilia is an example of a common sex linked disorder that is an X linked recessive trait.
