What can you compare a sinkhole to?
A sinkhole can be compared to a pothole on a road, as both are depressions or holes that form on the surface. Sinkholes can also be compared to caves, as both are voids formed underground that have the potential to collapse.
What are the health risks associated with using propane compared to natural gas?
The health risks associated with using propane compared to natural gas include potential carbon monoxide poisoning, fire hazards, and respiratory issues. Propane can be more dangerous if not handled properly due to its higher flammability and potential for leaks.
Does a crystal lattice have lower potential energy than a neutral atom?
Yes, in a crystal lattice, atoms are arranged in a repeating pattern that minimizes their potential energy. This arrangement is more stable and has lower potential energy compared to individual neutral atoms.
What do you call the state of a neuron when it is not firing a neural impulse?
The state of a neuron when it is not firing a neural impulse is called the resting potential. This is when the neuron is negatively charged inside compared to outside, waiting for a stimulus to change its electrical charge and initiate an action potential.
Why alkali metals have more negative electrode potential?
Alkali metals have more negative electrode potential because they have a strong tendency to lose electrons, making it easier for them to be oxidized at the electrode surface. This electron-donating tendency results in a more negative electrode potential compared to other elements.
How does threshold change during the relative refractory period?
During the relative refractory period, the threshold for excitation is increased compared to the resting threshold. This is because the membrane potential is closer to its resting state, making it more difficult to depolarize the cell and generate an action potential. It requires a stronger stimulus to overcome this increased threshold and trigger another action potential.
Which type of muscle cell exhibits a longer refractory period?
Cardiac muscle cells exhibit a longer refractory period compared to skeletal muscle cells. This is important in preventing tetanic contractions and ensuring that the heart muscle can effectively pump blood.
What is the population of Mexico compared to the population of the United Kingdom?
UK population is estimated 62,041,708 in 2010 Mexico population is estimated 111,211,789 in 2010
What is the time between ejaculation and the next arousal for males?
The refractory period, the time between ejaculation and the next arousal for males, can vary depending on factors such as age, health, and individual differences. On average, it can range from a few minutes to a few hours. Younger males tend to have shorter refractory periods compared to older males.
Which molecule, NAD or NADH, possesses higher potential energy?
NADH possesses higher potential energy compared to NAD.
How many times higher is the estimated rate of extinction for the species now compared to before humans appeared on earth?
1000
What are the advantages of algae to the economy?
A scientist estimated that algae could produce 120000L of fuel compared with 6000L of palm oil plants.
How old is the star capella?
Capella is estimated to be around 500 million to 700 million years old, which is relatively young compared to other stars in the universe.
Which species has the greater biotic potential is it pigs or rhinos?
Pigs have a greater biotic potential compared to rhinos. This means that they can produce more offspring in the same amount of time.
Who was smarter Einstein or Hitler?
Neither Einstein or Hitler ever took an IQ test, so it cannot be known who they compared in terms of raw intelligence. Nevertheless, their scores have both been estimated, judging from what they said and how logical their thoughts were. Hitler was estimated to have an IQ of 141, and Einstein was estimated to have an IQ of 160.
Which town is larger Wagga or Dubbo?
Wagga Wagga is larger. In late 2010, its population was estimated at 55,381, compared to Dubbo's population of 29,361.
Can skeletal muscle be tetanised?
Yes, because of the short refractory period of skeletal muscle (compared to cardiac muscle), skeletal muscle can be restimulated before the muscle is completely relaxed. If repeated enough times, the contractions fuse together i.e. they become tetanised.
