Answer:
A) Photosphere
Explanation:
B. red giant stage
C. planetary nebula stage
D. black dwarf stage
Answer: B. red giant stage
When the sun runs out of fuel-hydrogen, its atmosphere expands and it becomes a red-giant star. The Sun would leave the main-sequence stage and enter the red-giant stage in which huge pressure generated in its core pushes the atmosphere outwards making it expand and nuclear fusion reaction of heavier nuclei starts. The end stage of Sun would be formation of a white dwarf.
Thus, from the given options, correct answer is B. red giant stage
The final stage in the sun's life cycle is the black dwarf stage. The black dwarf stage is proposed to be the final stage in the life cycle of a white dwarf, after it has exhausted its nuclear fuel and undergone gravitational collapse.
The correct option is D.
The life cycle of a star like the sun can be divided into several stages. The specific sequence of stages depends on the mass of the star. However, for a star like the sun, the stages are as follows:
Main Sequence: The sun is currently in the main sequence stage, where hydrogen fusion occurs in its core, producing energy.
Red Giant: As the sun exhausts its hydrogen fuel, it will enter the red giant stage. During this stage, the sun's core contracts while the outer layers expand, causing the sun to become larger and cooler.
Planetary Nebula: In the next stage, the sun will shed its outer layers, forming a glowing shell of gas and dust called a planetary nebula. This process exposes the core of the star.
White Dwarf: After the planetary nebula stage, what remains of the sun's core will collapse inward due to gravitational forces. Black Dwarf: The final stage in the sun's life cycle is the black dwarf stage.
Hence , D is the correct option

Yes, the importance of an element in the body related to its percentage of body weight.
That element that is present in a large amount are more important for the structure and function of the body. The human body is approximately 99% consist of six elements which is Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus.
The five elements are present in 0.85% on the basis of boy weight which is sulfur, potassium, sodium, chlorine, and magnesium so we can conclude that percentage of element in the body tells us about its importance.

The importance of an element in the body is not solely based on its percentage of body weight. Elements' importance is determined by their function and essentiality to biological processes. Oxygen, although abundant in the body, is necessary for cellular respiration and energy production.
The importance of an element in the body is not directly related to its percentage of body weight. While some elements may have a higher percentage in the body, their importance is determined by their function and essentiality to biological processes.
For example, oxygen is the most abundant element in the body and has a high percentage of body weight. This is because oxygen is essential for cellular respiration and energy production.
On the other hand, elements like iodine and iron may have a lower percentage in the body, but they are crucial for functions like thyroid hormone synthesis and oxygen transportation, respectively.
