Answer:
The mass of a star determines its life cycle, that is, more the mass, shorter will be its life cycle. The mass of the star is determined by the concentration of matter, which is found within its nebula. In the nebula, with time, the hydrogen gas comes in close proximity with each other due to gravity and starts to spin.
With the brisk spinning, the gas heats up and turns into a protostar. The temperature now reaches 15,000,000 degrees and within the core of the cloud, the phenomenon of nuclear fusion takes place. The cloud now contracts a little, starts to glow brightly, and turns stable. The cloud now becomes a prime sequence star, and will stay in this phase for millions of years, the Sun of our galaxy is in this stage at the moment.

Wegener proposed the hypothesis of continental drift, which suggested that continents are in constant motion on the surface of Earth. Over time Pangaea began breaking apart, and the continents slowly moved to their present positions.
<h3>What is Continental Drift ?</h3>
The theory of continental drift is most associated with the scientist Alfred Wegener.
- Wegener's continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.
- The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.

As we break down the glucose via glycolsis and then Kreb cycle , the carbons releases from of our body in the gaseous form called CO2 !!
38 ATP is formed as a result !! And in waste CO2 is formed !!
The correct answer choice is answer B.) The fossil record provides evidence of a common ancestor to many species. Hope this helped!
A carpel on a typical flower is located on the bud tips, what I mean is that where the stamen is nearly right beside it is the carpel. A carpel is like the reproductive organism of a flower.
