Experiment 8.1 Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its

INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria

SCIENCE - FORM 2 Nutrition CLASSES OF FOOD 1. Food is a basic necessity for all living things. 2. Food is important in order to : (a) Provide energy to carry out physical activities. (b) Provide energy for the physiological activities in life such as reproduction‚ digestion and excretion. (c) Build new cells and ti repair tissues in the body.

Extended experimental investigation: effects on membranes of environmental stress Background It is not possible to observe membranes directly‚ so this investigation is an indirect study of the effects of different substances and treatments on living beetroot cells. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded by a membrane (Figure 1). Contained in the vacuole is the red pigment anthocyanin‚ which gives the beetroot its

protein-energy malnutrition (Kwashiakor): Wrong proportion of nutrients e.g. too much carbohydrates (starchy foods) and a lack of protein can lead to Kwashiakor in young children. Kwashiakor characterized by edema‚ anorexia‚ ulcerating dermatoses. 5. Vitamin‚ mineral and fiber deficiency diseases - Lacking key nutrients.

Pre-Lab 1 Assignment Quantitative Analysis of Biomolecules Biochemical analysis involves the characterization of biomolecules within a sample using appropriate laboratory techniques. There are two principal approaches: 1. Qualitative analysis – where a sample is analyzed to determine whether a biomolecule is present or absent. As an example‚ a blood sample might be analyzed for a specific antibody or a bacterial cell might be probed for a nucleic acid sequence. 2. Quantitative analysis

Memory and Biology There are many events in a person’s life that leave an impression or may “change” a person’s perspective or path. From birth to death the mind is recording lessons and adding to the infinite storage space known as memory. Classical conditioning Lives are filled with many lessons; some of these are learned through classical conditioning‚ operant conditioning‚ and behavioral observation. A simple example of classical conditioning would

In Biology 1115‚ I learned a great deal about cytoskeleton. I have been able to recognize the functions of molecular structures which are microtubules‚ microfilament and intermediate filaments‚ but I still have confusion about those structures. For example‚ I always misunderstand the differences between microtubules and microfilament. Therefore‚ I got wrong in some multiple choices of this midterm. I went back to the notes and read them again after seeing my midterm which can help me to clarify and
