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:
Because oxygen is circulated throughout the body via the bloodstream, there is a strong connection between the cardiovascular system and the <em><u>respiratory</u></em> system.
Explanation:
The cardiovascular system is responsible for the transport of oxygen to all tissues of the body, in addition to the removal of carbon dioxide, which depends on the close interaction with the respiratory system.
A summary of the strong connection between the cardiovascular and respiratory systems is
:
Blood contains red blood cells, which are responsible for transporting O₂ and CO₂ by binding to the hemoglobin molecule, present in these structures. The respiratory system is responsible for providing air with O₂ and removing CO₂, a process that depends on gas exchange at the level of the pulmonary alveolus.
The correct answer is C.
The zygote is a single fertilized egg cell that the embryo develops from.
This one cell possesses one copy of DNA that is going to be passed to all other cells in the embryo because all other cells of the embryo develop through mitotic divisions of the zygote.
Therefore, if a mutation happens in the zygote DNA, all of the cells in the embryo are going to have it as well.

Answer:
Soil Erosion
Explanation:
Basically, tillage breaks soil up, destroying its overall structure. It encourages surface runoff and therefore soil erodes more easily. In some cases soil erosion is beneficial, but in most cases, it is not. Tillage has also been found to cause the emissions of more toxic gases such as N20.
