6. Briefly describe the two meiotic events that contribute to genetic diversity in a population. Each gamete (sex cell) is unique due to a process during meiosis called cross-over which (simplified) swaps around some genes to create unique chromosome combinations. meiosis helps to create a population that is not only physically and genetically different but also one, which is perfectly fit to survive.…

23.7 23.8 Relate the structure of blood vessels to their function. Explain how and why blood pressure changes as blood moves away from the heart. Explain how blood is moved back to the heart. 23.9 Explain how blood pressure is measured. Give examples of normal and high blood pressure readings. Describe lifestyle changes that can help to reduce high blood pressure. 23.10 Explain how blood flow through capillaries is regulated. 23.11 Explain how the structure of a capillary relates to its functions.…
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 happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.…

The cardiac cycle is the cycle of events that occurs as the heart contracts. There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood into the arteries.…
The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities, presence of particular enzymes, and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria, Bacillus Subtilis.…
