THIS IS ON YOUR TEST!!! Which of the following could NOT cause a population to develop into two distinct species? A. behavioral isolation B. temporal isolation c. geographic isolation D. Interbreeding Which of the following could NOT cause a population to develop into two distinct species? A. behavioral isolation B. temporal isolation c. geographic isolation D. Interbreeding A is WRONG because the behavioral isolation leads to speciation Which of the following could NOT cause a population to develop into two distinct species? A. behavioral isolation B. temporal isolation c. geographic isolation D. Interbreeding B is WRONG because the behavioral isolation leads to speciation Which of the following could NOT cause a population to develop into two distinct species? A. behavioral isolation B. temporal isolation c. geographic isolation D. Interbreeding C is WRONG because the behavioral isolation leads to speciation Which of the following could NOT cause a population to develop into two distinct species? A. behavioral isolation B. temporal isolation c. geographic isolation D. Interbreeding D is WRONG because interbreeding shares genes and decreases likelihood of speciation On any given Friday, two teams will face each other to determine their destiny… So, Mr. D wants to know… Football Review: Teams Team one: 1. Michael Team 2: 1. Chris 2. Kevon 2. Eric 3. Kelvin 3. Barry 3. JerTayvious Football Review: Rules • You will work with your team to get the right answer • When the question is read, you will have 25 seconds to think of and write down your answer • The team that that raises all their paddles with the same answer first answers first. Mr. D will randomly select a player’s # to answer. The player can “double the distance” by explaining why. If they get it right, they move twice as far (“10 yards”). If wrong, just 5 yards. • (interception) If the team gets it wrong, the other team can answer • (fumble) If they don’t know/get it wrong, Mr. D will call out a random #; the first person who raises their hand for that number (either team) can answer in 10 seconds. • If they get it right, they move a spot (5 yards) • If the person who answers first gets it wrong, the other person can answer; if they don’t know or get it wrong, we move onto the next question • 4 points equals a touchdown which equals one point. Then we restart in the middle and the team that didn’t score will starting answering. Football Review: Penalties • There is no talking when someone answers a question, unless it’s a fumble and the person is asking within 10 seconds. Penalty: move back one spot • There is no talking between teams. Penalty: lose a point; if no points, one strike • All class rules apply (no standing, throwing, disrespectful speech). If you break them, you will leave your team and work “ on the sidelines” on an assignment independently and silently. If you continue to be disruptive, you will receive a detention • If three people break the rules (three strikes), we will all work on a review sheet silently Football Review: Encouragement • You may encourage your teammates between questions but must be silent once Mr. D raises his hand for the next question. • You may contribute the answer quietly during a fumble • The team that wins gets a ticket for each “touchdown” scored and one bonus point. • The second team gets a ticket for each “touchdown” scored.
