The earth science that involves the study of structure and composition of the earth includes different branches such as geology‚ oceanography‚ meteorology‚ paleontology‚ etc. Life science is also known as biology‚ which deals with the study of evolution‚ development‚ distribution‚ structure‚ origin and function of the living things. It is categorized into different branches such as botany‚ genetics‚ zoology‚ medicine‚ etc. The mathematical science involves

between sexual selection and human reproductive behaviour. (24) Sexual selection can be used to explain certain characteristics or behaviours which increase an individual’s reproductive success. These characteristics may get exaggerated over evolutionary time. In humans‚ these characteristics may include good physical and mental health‚ as well as physical features such as good looks etc. these characteristics are attractive because they show an ability to reproduce and pass on these genes to offspring

• Explanation of the concept of natural selection and how it takes place The theory of natural selection was developed by Charles Darwin and Alfred Russel Wallace. They suggested that the mechanism of natural selection was that some organisms have characteristics that are better suited to the environment they live in then others that don’t have these characteristics. These organisms are then more expected to survive to reproduce offspring with these characteristics‚ over generations new organisms

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

creating fertile progeny change genetically over time. The Hardy-Weinberg equilibrium accounts for gene pools that do not change genetically over time. In this experiment‚ I intended to determine whether the sample population consisting of my fellow biology lab classmates would fall in the Hardy-Weinberg equilibrium with respect to the ALU insert from human chromosome 8. My hypothesis was that this sample population would fall in the Hardy-Weinberg equilibrium with respect to the ALU insert. To analyze

Tomato Sweetness Jessica Pursell American InterContinental University 01/18/2015 Biology IP2 Introduction You and your neighbor have small kitchen gardens where you both grow tomatoes. His blotchy green and red tomatoes taste much sweeter than your perfectly uniform red ones. Could the sweetness of the tomatoes be effected by the green chloroplasts in the fruit? Hypothesis I personally think that the green chloroplasts do play a part in the sweetness of the tomatoes because it doesn’t
