they would be melted and vaporized in the atmosphere.
Explanation:
Meteoroids is piece of solar rock before it strikes the earth surface. Meteorites are rocks that strikes the surface of the earth from space.
- In earth science, meteorite impacts are often attributed with mass extinctions on the earth surface.
- For a meteorite to reach the earth surface, it must has a very large diameter.
- This big rocky mass must be able to escape the earth geomagnetic field and the ionizing radiation in the upper reaches of the earth atmosphere.
- Meteoroids of smaller sizes cannot escape the earth's atmosphere and would completely ionized and melted.

Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

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.
False. Continental slopes are fairly shallow and more of a gentle slope. Hope this helps!
