Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

what are the two forms of acid deposition. I have also watched some videos about acid rain? I also should say the most important thing that scientists are doing in their labs. Where acid rain is most effects on which states and does it affect human when we swim in a really high acidic ocean. Acid rain is a mixture of water and gases that have a pH of 5 or lower and it is found in our atmosphere. Acid rain is made out of two main gases nitrogen dioxide which is formed from cars‚ and sulfur dioxide

The phylum contains about 7000 living species‚[1] making it the second-largest grouping of deuterostomes (a superphylum)‚ after thechordates (which include the vertebrates‚ such as birds‚ fish‚ mammals‚ and reptiles). Echinoderms are also the largest phylum that has no freshwater or terrestrial (land-based) representatives. Aside from the hard-to-classify Arkarua (a Precambrian animal with Echinoderm-like pentamerous radial symmetry)‚ the

movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion of water. Water

Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in

In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both

Under these conditions‚ people stayed indoors with an air purifier running and remain as motionless as possible when air population was active according to U.S. Embassy Beijing guidelines.

11.1 Washing with cold distilled water Washing process is not only remove soluble protein‚ fat‚ and pro-oxidant‚ but may also remove antioxidant. Therefore the oxidative stability of muscle ultimately depends upon the antioxidant/prooxidant balance that remains after the muscle is washed. It suggests that washing may promote oxidation in mince since it effectively removes antioxidants from the fish. In addition‚ the neutral lipids are more easily removed than polar lipids‚ phospholipids and free

Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light
