Which of the following was an evolutionary benefit of polarity? Polarity made collecting predictable nutrients more efficient Polarity made scavenging for randomly located nutrients more efficient Ionic charges from polarity allowed animals to physically repel predators Each cell could do all required tasks more efficiently, leading to the organ systems of today's animals Question 2 0 pts Which of the following would contribute to sympatric speciation? Errors in chromosome duplication in plants that lead to extra chromosomes A geographical barrier that isolates populations Mating behaviors that are not tied to foods in the same geographical area Mating behaviors associated with different foods that are the same within a geographical area Genetic Drift can occur through which of the following? Environmental factors that shape allele frequencies into disruptive, stabilizing, or directional selection Can only occur through natural disasters Through alleles being dominant or recessive When a population experiences high levels of sexual selection to shape allele frequencies .

HH , HT , TH , TT What are the probabilities of getting each of the following outcomes? a. Exactly 1 head b. At least 1 head c. No more than 2 heads a. The probability of getting exactly 1 head is 2 1 . b. The probability of getting at least 1 head is 4 3 . c. The probability of getting no more than 2 heads is 4 1 . A report asked people who got their news from television which television sector they relied on primarily for their news: local TV, network TV, or cable TV.

You are an astronaut that is going on a Space Exploration Mission to Mars. The mission is going well until you are hit by a fierce and completely unexpected dust storm. Your team needs to abort the mission and leave the planet immediately. As the crew members are trying to quickly board the ship, you get hit by an antenna and thrown off into the distance. Your team assumes that you are dead and leaves without youll The storm passes. You wake up and are thankful that you are alive but you quickly realize that you have been left alone on Mars!! You must now figure out how to survive until your crew returns to Mars on the next mission. You decide to grow potatoes as a food source. One day, as you are working on your farming project, you encounter a small creature. You realize that the creature has a ravenous appetite for potatoes!l You are immediately intrigued by this alien. You know it will be quite a while before a rescue mission arrives, so you decide to pass the time by trying to analyze the creature's bioenergetics pathway. During your research you realize that the alien has a similar cellular structure to organisms on Earth, having several of the same organelles. Surprisingly, the creature appears to be able to use the tiny amounts of Oxygen in the atmosphere for its metabolism. However, this creature is Silicon-based not Carbon-based. You also notice that this creature uses a triphosphate energy molecule which you name MTP because it is an unknown Martian triphosphatel You perform your biochemical analysis and come up with the following: Step \#1: A linear metabolic pathway begins using a molecule containing 270 Silicon atoms (Si i 270 ). This is the first molecule in the pathway. Twenty-seven MTP molecules are used up as Si 270 is broken down into three molecules of Si 90 - Nine molecules of a substance called ZADH are also formed during this step. Step \#2: Each Si 90 is further broken down. Six molecules of SiO 2 are released as the Si 90 breaks down into three molecules of Si 28 . Six MTP and seven ZADH molecules are also produced during this break down. Step \#3: Each Si 28 goes through a cyclic metabolic pathway. Each Si 28 is completely broken down to release 28 SiO 2 molecules. For each Si 28 that is broken down, 10 MTP , 5 ZADH , and 3 ZADH 2 are also produced. Step H4: The ZADH and ZADH 2 molecules are then further processed during a stage that appears to be similar to electron transport. During this stage, each molecule of ZADH will produce 8 MTP and each molecule of ZADH 2 will produce 6 MTP. NOTE: Each ZADH molecule produced during step \#1 will be converted into 2 molecule of ZADH 2 before it enters the electron transport stage (step \#4). Sketch the alien's metabolic pathway as it is described in steps 1,2, and 3 above (You do not need to draw step 4). (12 marks) Step 1: Sizx 3 sisa + 92ADH +27MTP Step 2: Sise 3 sia + 6 SiO 2 + 72 ADH + 6 M7P Step 3: Sia 28 1 O 2 + 10 M 7 P + 5 Z A DH + 32 A D H 2 During the complete metab.

Write the definition of the function insertBack() as a member function of the class AnyList as follows: - Parameter: An int storing a value. - The function creates a new node that stores the value passed by the parameter, and inserts the new node at the end of the list. Make sure you use the initializer list constructor. This way, you will be using only one function, which is more efficiend than using two (default constructor + setData).

Write the definition of a function printArray, which has two parameters. The first parameter is an array of integers and the second is an int, the number of elements in the array. The function does not return a value. Using a loop, the function prints out each element of the array, on a line by itself, in the order the elements appear in the array (first followed by second then third and so on) and adds the elements of the array. It also prints the total. .
