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.

Answers

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.

I just did this question and it's A and D

In the atmosphere water vapor condenses to form clouds.   Please select the best answer from the choices provided T F

Answers

Answer: The given statement is True.

Clouds are formed due to condensation of water vapors. Condensation can be described as a process of change of gaseous form of water (that is water vapor) into liquid form.

When sunlight strikes various aquatic bodies, water is heated up and it rises high in the atmosphere in the form of water vapors.

When these vapors meet a lower temperature in the atmosphere, they cool and the air loses its capacity to hold them.

Due to this, vapors condense and form clouds.

Thus, given statement is True.

true is the correct answer

Jacob has a bucket of ice. He covers the bucket with a lid and sets it in the sun. The ice melts into liquid water. How does the mass of the ice compare with the mass of the water? A. The mass of the ice is the same as the mass of the water. B. The mass of the ice is more than the mass of the water. C. The mass of the ice is less than the mass of the water. D. There is no way to determine this from the information given.

Answers

Answer:

A

Explanation:

According to law of conservation of energy:

Mass (or energy) can neither be created nor destroyed but they can be changed into different forms.

As there is a lid on the bucket there is no evaporation happening, hence the mass will remain same.

A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.

The sun's apparent motion across the sky from East to West daily is due to the A) rotation of the sun. B) rotation of the earth. C) orbit of the earth around the sun. D) orbit of the sun around the earth.

Answers

B)rotation of earth because we rotate around the sun so when your area faces away from the sun it looks like the sun is setting in your point of view.
B) rotation of the earth.

The sun is relatively fixed. It is the rotation of the Earth that makes it appear as if the Sun is moving from East to West.
