Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which plant has started to grow. A non-germinating seed is usually dry, and a new plant has not yet emerged.The data that she gathered is displayed in the graph below.Which of the following statements are true concerning the data that Callie gathered during the lab? Choose the two that apply.
A.The germinating corn seed produced more energy than the non-germinating corn seed.
B.The non-germinating corn seed produced more carbon dioxide than the germinating corn seed.
C. The germinating corn seed consumed more oxygen than the non-germinating corn seed.
D. The non-germinating corn seed performed more cellular respiration and the germinating corn seed.
E. The non-germinating corn seed performed cellular respiration and the germinating corn seed performed fermentation.

Answer 1
Answer:

The correct options are :

(A) The germinating corn seed produced more energy than the non-germinating corn seed.

(C) The germinating corn seed consumed more oxygen than the non-germinating corn seed.

information from the graph:

  • We can clearly see in the graph that the slope of the germinating seed is steeper than that of the non-germinating seed.
  • Since the germinating seed has a steeper graph, it shows that its rate of consumption of oxygen is higher than that of the non-germinating seed.
  • As the germinating seed consumes more oxygen, it implies that it produces more energy than the non-germinating seed.

A) Fall Line B) Sand Hills C) Coastal Plain D) Barrier Islands

Answers

Answer:

Option A) Fall Line

Explanation:

A fall line is a geological boundary that is formed between an upland region and a plain beneath. Usually, the regions are identified by falls or rapids when rivers and streams cross or meet.

One interesting feature is that the fall lines are formed when rivers meander through regions of weak rock structure. Normally, the rock structure is sedimentary rock structure (layered). The rivers tear into the earth by erosion, abrasion and attrition.

In addition, plate tectonics play an important role. The movement of the earth's plates causes the falls. Some are formed by the rapid freeze-thawing action of large blocks of ice.

If the slope of a position versus time graph is downward what kind of motion produced the graph

Answers

If the position vs time graph is sloping downward, that says that the position is
getting smaller as time goes on.  That means that the object is approaching
the place where you're measuring position from.

gas has a volume of 185 ml and pressure of 310 mm hg. The desiered volume is 74.0 ml. What is the required new pressure

Answers

Answer:

The required new pressure is 775 mm hg.

Explanation:

We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.

We have to find the required new pressure.

Let the required new pressure be '\text{P}_2'.

As we know that Boyle's law formula states that;

                    P_1 * V_1 = P_2 * V_2

where, P_1 = original pressure of gas in the container = 310 mm hg

           P_2 = required new pressure

            V_1 = volume of gas in the container = 185 ml

            V_2 = desired new volume of the gas = 74 ml

So,  P_2 = (P_1 * V_1)/(V_2)  

       P_2 = (310 * 185)/(74)

            =  775 mm hg

Hence, the required new pressure is 775 mm hg.
