[Q]: Please answer correctly the following question related to the paragraph below. Which group had people with fewer changes in cellular structure? Dr. Bill studies 2 groups of patients, group S composed of individuals with siclke-cell anemia, and group N with normal blood and no health issues. Hint: The primary role of red blood cells in the circulatory system is to transport oxygen to the tissues. The actual carrier of oxygen molecules is the protein hemoglobin, which binds to the oxygen and moves it throughout the body, releasing it in areas where the concentration of dissolved oxygen is low. A certain mutation in the gene for hemoglobin causes a slight change in the structure of this crucial protein, resulting in a disease called sickle-cell anemia. For people with this mutation, the hemoglobin produced by their red blood cells has a tendency to clump together, distorting the shape of the red blood cells and giving rise to the crescent-shaped cells seen above. By understanding the changes in structure that are the underlying cause of this disease, we have developed various ways to treat and manage this illness.

[Q]: Please answer correctly the following question related to the paragraph below. Which snake had more rattles, the second or the third snake Dan found? Dan found three rattle snakes: one only had one rattle, the second snake had 4 rattles and the third snake had seven rattles on its tail. Hint: At birth, a rattlesnake hatchling has only a small button or 'primordial rattle' which is firmly attached to the tip of the tail.[13] The first segment is added when the hatchling sheds its skin for the first time.[14] A new section is added each time the skin is shed until a rattle is formed. The rattle grows as the snake ages but segments are also prone to breaking off and hence the length of a rattle is not a reliable indicator of the age of a snake.[15]

[Q]: Please answer correctly the following question related to the paragraph below. If the biologists predict an increase in deer birth rates are there a high amount of resources or low amount of resources? A team of biologists has been monitoring the deer population in the state of Wisconsin. They use past data and current conditions to predict how the population will grow or shrink and recommend how many hunting licenses the state should issue during hunting season to keep the population stable. Hint: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease.

[Q]: Please answer correctly the following question related to the paragraph below. Where do they have the capability to see fewer faint objects, at Tim's or at Bill's? Whenever Bill visited Tim's house, they couldn't see that many stars when stargazing . Tim lived in the city. The sky was much clearer at night at Bill's place, because he lived in a rural area. Hint: Astronomy is very sensitive to light pollution. The night sky viewed from a city bears no resemblance to what can be seen from dark skies.[78] Skyglow (the scattering of light in the atmosphere at night) reduces the contrast between stars and galaxies and the sky itself, making it much harder to see fainter objects. This is one factor that has caused newer telescopes to be built in increasingly remote areas.
