The sun provides a handy benchmark for describing other stars. The mass of this solar system's sun gives us a unit for measuring other stars' masses. Similarly, the sun's luminosity and surface temperature define the center of the Hertzsprung-Russell Diagram (H-R Diagram). Plotting a star on this chart reliably predicts other qualities of the star, such as mass and age. The main sequence phase of a star's life cycle is that time during which hydrogen fusion takes place in its core. But in terms of the H-R Diagram, "main sequence" also refers to a roughly diagonal, slightly S-curved line stretching between the upper-left and lower-right corners on which main sequence stars chart. They maintain a predictable relationship between luminosity and temperature: the brighter, the hotter. Both of these traits increase with a star's mass; a star indicated closer to the upper-left corner will be "heavier" than our sun, while lower-right main sequence stars will be "lighter."
Red Giants
Should astronomers plot a newly discovered star in the upper-right corner of the H-R Diagram, being both bright yet cool, they'll immediately know what phase of its life cycle the star is enduring. A red giant's core, hot enough to fuse helium and even heavier elements, has pushed its shell layers so far out that they can cool into the red spectrum. They owe their great luminosity not to their temperature, but to their size: bigger stars radiate more light energy.
Answer:
<h2>Interdependence is mutual dependence between things. If you study biology, you'll discover that there is a great deal of interdependence between plants and animals. Inter- means "between," so interdependence is dependence between things. We often use interdependence to describe complex systems.</h2><h2>All living things depend on their environment to supply them with what they need, including food, water, and shelter. ... Many living things interact with other organisms in their environment. In fact, they may need other organisms in order to survive. This is known as interdependence.</h2>

<h2>Hopes this helps. Mark as brainlest plz!</h2>
Answer: B
Explanation:
An endangered species is a species thats on the verge of extinction meaning it will be wiped out completley
Destruction of coral reefs would cause an imbalance in the ecosystem. Some species could be driven to extinction.
Coral reefs are the base of the most diverse marine ecosystem in the world. They are often referred to as the ‘rainforest’ of the oceans and seas. They provide shelter for cnidarians, sponges, crustaceans, and etcetera and provide hiding grounds from predators.
After DNA replication has taken place, two molecules, each with one original and new strand is formed. This supports the idea of DNA replication.
