Answer:
3. Spiral galaxies revolve around a single point and gas spinning arms of stars extending from the center
4. Star 4 will stay on the main sequence for the longest time.
Explanation:
A galaxy is a system of gases, dust, and billions of stars and their solar systems, and dark matter which are bound together by gravity. Types of galaxies based on structure are elliptical, spiral, irregular and barred spiral.
Spiral galaxies have a spiral shape consisting of a central bulge, a halo, a disk, and spiral arms. At the center of revolution of the galaxy is the bulge which contains older stars. The disk contains gas, dust and younger stars which extend as spiral arms. The halo is found around the bulge and contains old cluster of stars. Ab example of a spiral galaxy is our Milky Way galaxy.
4. The mass of a star is related to its luminosity as well as its position on the main sequence. High solar mass stars have high luminosity and therefore spend the least time on the main sequence whereas low solar mass stars have low luminosity and spend the most time on the main sequence.
Therefore, Star 4 having the lowest solar mass will spend the most time on the main sequence.
C photic zone because that is where sunlight can reach and you need sun for photosynthesis
I believe the function of this process would be B. To deliver proteins to other locations in the cell.
Answer:
More carbon dioxide (CO2) would be in our atmosphere.
Explanation:
Plants undergoing photosynthesis take in carbon dioxide (CO2) and give out oxygen (O2). They essentially use the CO2 to make sugars that keep them alive. Excess plant CO2 is then given off back into the environment, just like how we exhale CO2 after taking a breath.
So, no plants to take in the CO2 equals more CO2 in the environment.
Think of it kinda like this: I like Pop Tarts. If there is less or none of me in the world, there are more Pop Tarts just... out there... waiting to be eaten.
<span>the area that would most likely experience the greatest amount of natural erosion is : the coastline
When the waves crashed the coastline it will started a process called abration, when the land is detoriorated over time due to its friction with thewave
The best method to prevene this is by planting mangroves near the coastline</span>
