Answer:
Interdependence
Coevolution
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

Answer:
B)
Explanation:
Vaccinations build the body's ability to fight illnesses by introducing a de-activated virus to the body, which then produces antibodies that can kill the virus. The immune system can then "remember" the viruses' structure for future encounters.

Multicellular organisms are organized into various levels, including cells, tissues, organs, organ systems, and organisms. Each level has a unique role and is often comprised of lower levels, such as organs being made up of tissues, which are made up of cells.
Yes, indeed, multicellular organisms can be further organized into other levels. These include the cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels. For instance, molecules combine to form cells, cells combine to make tissues, tissues form organs, organs come together to form organ systems, and organ systems combine to form organisms. Organisms are individual living entities. For instance, every single tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also considered organisms and are typically referred to as microorganisms.
