What are sunspots? Pls help

Biology
1 answer:
liq [111]3 years ago
5 0

Answer:

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.

Explanation:

The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.

Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.

How does the cardiovascular system interact with the respiratory system?
jek_recluse [69]

Answer:

The circulatory and respiratory systems work together to pump blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and the bronchioles.

True or false: The energy contained in the food we eat directly powers all of our cellular activities. If false, please make it
Gwar [14]

Answer:

False

"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".

Explanation:

The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.

ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
