The HomininsBeginning in the late Miocene and into the early Pliocene, upright walking tendencies began to develop among the hominin tribe. Upright walking tendencies slowly transformed into obligate bipedalism during the pliocene within the hominin lineage. This shift in locomotor strategy is notably marked by the gradual change in arm to leg ratio that we see when comparing early and later hominins. Early hominins have short legs and very long arms while later hominins have longer legs and short arms. Your task for this activity will be to compare and contrast the locomotor strategies of the following two hominin species: Ardipithecus ramidus and Australopithecus afarensis. You will accomplish this by answering the following questions.Before you begin make sure view all relevant reading material so that you can give me informed opinions.Which hominin had the best arboreal capabilities (look at both upper and lower extremities)? Make sure you explain your answer and give me at least one features that backup your claim. The feature that you choose has to be from lower extremities.Which hominins was the first to not just be an upright walker but an obligate biped (this means you have no choice but to walk on two legs)? Make sure you explain your answer using the same feature that you used when looking at the other hominin for comparative purposes. Lastly, I would like you to give a short summary of the notable transformations in locomotor strategy that occur over time as seen from Ardipithecus ramidus to Australopithecus afarensis.

CircuitsInstructions: For each circuit presented, you will construct the circuit using power-point shapes (resistors, wires, meters,...). In addition, based on the voltage values, you will calculate the total resistance and the total current for each circuit. The power-point file that you are to work on is attached to this page. Open it, perform the work, save it, and lastly upload it to the link provided. Refer back to the video in the previous module if you need a start. NOTE: When placing the ammeter in its place, you are measuring the current (coming out of) that would flow back through the battery.1. Two resistors in series: Construct the circuit on your breadboard for the two-resistor series circuit. Place an ammeter to measure the TOTAL current in the circuit.Measure the voltage across any of the two resistors. Drag the voltmeter to a convenient spot and take two wires to hook it up properly to measure the desired voltage. Place the value of the reading (what it should read ideally) in the space provided on the sheet.Use the wires provided. Save the red for the power input and then use whatever colors you prefer, or your TA prefers, for the meters and and return wire.2. Two resistors in parallel: Construct the circuit on your breadboard for the two-resistor parallel circuit. Place an ammeter to measure the TOTAL current in the circuit.Measure the voltage across any of the two resistors. Drag the voltmeter to a convenient spot and take two wires to hook it up properly to measure the desired voltage. Place the value of the reading (what it should read ideally) in the space provided on the sheet.Use the wires provided. Save the red for the power input and then use whatever colors you prefer, or your TA prefers, for the meters and and return wire.3. One resistor in series with a parallel combination: Construct the circuit of the single resistor in series with a parallel combination. Place the ammeter to measure the TOTAL current in the circuit.Measure the voltage across any of the three resistors. Drag the voltmeter to a convenient spot and take two wires to hook it up properly to measure the desired voltage. Place the value of the reading (what it should read ideally) in the space provided on the sheet.Use the wires provided. Save the red for the power input and then use whatever colors you prefer, or your TA prefers, for the meters and and return wire.
