Karen Pontifex TMA 1 1. Describe the four basic human body structure units and their functions The four basic human body structure units and their functions are: Cells, Tissues, Organs, and Systems. Cells Humans and all living things are made up of about 100 trillion small cells that can only be seen via a microscope. Cells can reproduce themselves and live independently. Some cells are specialized and become a different shape and size (elongated, oval, square, flat etc)

Evolution clashes, when there are changes being made to the age of the earth and the creation of man. The structure is described in the Bible as God created it; however, it describes the earth before the six days of creation. When thinking about the integration of evolutionary principles, as far as the scientific laws are concerned, there is no difference between the origin of the earth and all of its life. Could the Big Bang theory have happened? The Gap Theory, everything made out of nothing. Is the Gap

Eukaryotic Cells | | Part of our definition/description of what it means to be a living thing on Earth includes the assertion that living things are made of cells and cell products. In other words, we consider the cell to be a pretty fundamental structural aspect of life. Cells in our world come in two basic types, prokaryotic and eukaryotic. "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain. In biology, we use this word root to refer to the nucleus of a cell. "Pro"

ABSTRACT Stem cells have offered much hope by promising to greatly extend the numbers and range of patients who could benefit from transplants, and to provide cell replacement therapy to treat debilitating diseases such as diabetes, Parkinson's and Huntington's disease. The issue of stem cell research is politically charged, prompting biologists to begin engaging in ethical debates, Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation

providing and maintaining form in the body. Functioning mechanically, they provide a matrix that connects and binds the cells and organs and ultimately gives support to the body.Structurally, connective tissue is formed by three classes of components: cells, fibers, and ground substance. Unlike the other tissues (epithelium, muscle, and nerve), which are formed mainly by cells, the major constituent of connective tissue is the extracellular matrix. Extracellular matrices consist of different combinations

Heredity Heredity is the transmission from one generation to the next of factors that determine the traits of offspring. Although successful breeding of plants and animals was practiced by humans long before modern civilizations were established, there is no evidence that these early people understood the nature of hereditary factors or how they are transmitted through reproduction. EARLY HISTORY One of the early Greek philosophers, Pythagoras (582-509 BC), postulated that all traits of
