Biology is the science of life. That includes the structure‚ function‚ growth and evolution of a living organism‚ for example humans. There are many levels of study in biology that include botany‚ zoology‚ and the study of cells in a molecular level. Psychology is the science that studies mental processes and behavior. Like Biology‚ there are many levels of study in psychology that may include animal psychology‚ child psychology‚ ect. But what we may not take into consideration is that

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

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

1.The Effect of Boiled Lagundi Leaves to the Cough Abstract: Carbocistine is a kind of medicine who can cure cough. This investigatory project that we made shows that we can make our own cough reliever without spending money and we use herbal plants instead of chemicals. It is much affordable if you have a lagundi plant (vitex negudo l.) in your backyard. We add brown sugar so that the syrup will have a sweet taste. Background of the Study: Many people‚ especially those who are poor cannot

formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).
