Answer:
The temperature of the Sun's middle most layer is 6,000 degrees Celsius to 20,000 degrees Celsius.
Explanation:
- The sun is basically divided into inner and outer layer.
- The inner layer consists of Core, Radiative Zone and Convection Zone.
- The outer layer has Photosphere, chromosphere, transition region and corona.
- The chromosphere is the middle layer that can vary its temperature 6,000 degrees Celsius to 20,000 degrees.
- For most reason the temperature of chromosphere can be taken around 7700 degree Celsius but it varies.
Answer: Under these conditions, water osmosis causes water to accumulate in the cell from the external environment. The contractile vacuole acts as part of a protective mechanism that prevents the cell from absorbing too much water and possibly lysing (rupturing) through excessive internal pressure.
The answer is D as there are fluctuations which means that changes in the population of one affects the population of the other. as prey pop increases predator pop increases leading to a decease in prey pop which causes predator pop to decrease due to lack of food then prey increases and the cycle repeats
The photoreceptors would be your eyes, chemoreceptors skin, olfactory for nose and mechanoreceptors for obviously tongue hope this helps.
