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.

Well, there can be a tornado that is very severe when hot and cold air mixes making air swirl and create a triangular shaped spinning air. There are lightning storms when lightning bolts come from the sky, and there are hurricanes when there are lots of rain coming towards your way due to change in climate such as global warming, it often occurs in humid places.

If a wave has amplitude of 2 meters, a wavelength of 2 meters, and a frequency of 10 Hz, and a period of 1 second, then at what speed is the wave moving?

Answers

Answer:

20 m/s

Explanation:

The speed of a wave is given by:

$v=\lambda f$

where

$\lambda$ is the wavelength

f is the frequency

v is the speed

For the wave in this problem,

f = 10 Hz is the frequency

$\lambda=2 m$ is the wavelength

So the speed is

$v=(10 Hz)(2 m)=20 m/s$

True or false, most waves are generated by vibrations

What is currently the most supported theory about the future of the universe A.)the universe could remain exactly as it is today
B.) the universe may continue to expand
C.) stars could burn out , causing the universe to become dark and cold
D.) gravity could pull galaxies back together causing a reverse of the Big Bang

Answers

Answer:

B.) the universe may continue to expand

Explanation:

The steady state theory which states that the universe was, is and will be the same, has been discredited by two physicists who found the leftover energy from the big bang.

If you are listening to FM radio, you might have heard some static noise while changing stations, that noise is from the leftover energy from the big bang. This energy is called the dark energy.

The dark energy tries to rip everything apart while gravity tries to hold everything together.

It was observed that the dark energy is stronger than gravity.

The distance between the galaxies is increasing. This proves that the dark energy successfully defeated the gravity and expanted two massive objects in the universe.

Because of this dark energy the universe will continue to expand.

Note: Dark energy is also increasing the distance between protons in atomic nucleus in every atom in our body too. Chilly right?

the answer is B! it would continue to expand.....just took the test XD
