The evolutionary approach suggests that our behaviour is determined through natural selection; therefore it is coded into our genes through how we have adapted. It is a biological approach and states nature over nurture. A criticism of this approach is that it is determinist as it suggests that the way we behave is dictated through natural selection‚ for example in gender roles men being strong hunters and wanting a younger female partner. It ignores other suggestions‚ such as how we are brought

Animal Cell There are two types of cells that exist. Prokaryotic cells are simple cells that have few organelles. These cells don’t have a nucleus‚ but do have DNA. The DNA acts as a sort of “blueprint” for growth and reproduction in the cell. Prokaryotes are things like Bacteria. Eukaryotic cells are a lot more complex than a prokaryotic cell. These cells are able to convert food to energy‚ break down waste products‚ digest food‚ and assist with reproduction of new cells. Eukaryotic cells are in

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

Khoa Pham Theology 101 Dr. Nairn Relationship between God and Creation Genesis 1:26‚ God said “Let us make humankind in our image‚ according to our likeness; and let them have dominion over the fish of the sea‚ and over the bird of the air‚ and over the cattle‚ and over all the wild animal of the earth‚ and over every creeps upon the earth.” I think this is the image of human dignity. We can simplify this by saying that we are smarter than other creatures in this earth. In my opinion from

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing

Cuttlefish Evolutionary History The cuttlefish are an amazingly developed animal species with many specialised traits that make them perfectly suited to most‚ if not all‚ types of underwater environments. This is the animal this presentation will be looking into. Evolution is commonly described as a theory‚ However that is a common misconception‚ all different types of evolution‚ e.g. Darwinism and Lamarckism‚ are actually considered both fact and theory. As palaeontologist Stephen Jay Gould says

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;
