Introduction Good Morning Everyone. My name is and this is ‚ and . We will be presenting to you on how Light affects gene expression with focus on Maize leaves. This is an unrelated but neat photo of gem corn which is produced as a result of selective breeding. Anyways‚ most plants require light in order to grow and conduct photosynthesis. Plants that have been previously grown in the dark are incapable of photosynthesis since they lack chlorophyll and many polypeptides needed for light harvesting

QUESTIONS 1. According to the Hardy-Weinberg theorem‚ p + q 1 and p2 + 2pq + q2 1. What does each of these formulas mean‚ and how are the formulas derived? p + q 1: If you add all the dominant alleles for a gene to all the recessive alleles for the gene‚ you get all of the alleles for that gene‚ or 100% of the alleles for the gene. (Note: This assumes the gene has only two alleles.) p2 + 2pq + q2 1: If you combine all the individuals that are homozygous dominant for a gene with all

What is metabolism? All living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism. Metabolism includes two different types: catabolism and anabolism. Catabolism is destructive metabolism. Typically‚ in catabolism‚ larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy. Anabolism is constructive metabolism. Typically‚ in anabolism‚ small precursor

Radioactive isotopes (radioisotopes) are isotopes which are atoms of the same element that are chemically identical but vary in the number of neutrons they contain. Radioactive isotopes can participate in reactions just like non radioactive elements. Autoradiography is a technique used to trace the movements of certain substances around plants. An example of this is carbon 14. Carbon 14‚ a radioactive isotope‚is added to the carbon dioxide supply of the plant‚ to study the movement of products

C) Type of pollution. 1. WATER POLLUTION — any contamination of water that has deteriorated its quality to living things. * SOURCE: There are many causes for water pollution such as effluent outfalls from factories‚ refineries and waste treatment plants. More to that‚ the contaminant that enter the water supply from the soil or groundwater systems. Soils and groundwater contain residue of human agricultural practise and improperly disposed of industrial wastes. Other than that‚ the habits

11-9-12 Article Summary In Power Failure‚ Megan Scudellari talks about mitochondrial dysfunction and how it can influence complex diseases. She introduces Douglass Wallace and talks about how he came up with this idea that maybe the mitochondria is linked to certain diseases such as Alzheimer’s and cancers. He was the first person ever to discover that mutations in mtDNA cause disease and from that point on his research began to expand. At first many scientists turned a blind eye to this theory

Investigation into finding out the Effect of the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2)

1.05 assessment by ??????? 1) What does it mean when scientists say that living organisms share a universal genetic code? Genetic code means DNA and when organisms share a univeral genetic code they share a structure of DNA. 2) How does a universal genetic code relate to the hypotheses about the origin of life on Earth?Universal Genetic code would indicate that all organisms descended from a common ancestor‚ seeing how all organsims share a

The purpose of this investigation was to see if doing push ups affects one’s heart rate. It was found that the exercise that was performed did affect the heart rate. Therefore‚ doing push ups did increase the heart rate. If doing exercise increases one’s heart rate‚ then doing push ups affects the heart rate. This investigation deals with analyzing the effect on doing an exercise‚ in this case- pushups; will increase one’s heart rate. I have analyzed ten boys between the ages of fifteen and seventeen
