Using the information in the passage, rank the types of galaxies by their ability to form new stars, from most to least activity
Alex Ar [27]

Answer:

The correct answer is number 2. Elliptical, Spiral, Irregular.

Explanation:

Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.

So we are going to answer this question with our own knowledge.

The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."

That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.

Scientists still studying the universe and the galaxies to understand the way galaxies are formed.

Which two atoms could be the "before'' and ''after'' of an alpha ejection
spin [16.1K]
The answer would be uranium and thorium. When an alpha ejects a particle, it will create a new atom. So, when uranium ejects an alpha particle, it will produce thorium.  They call this process as the alpha decay. Alpha decay often happens on atoms that are abundant nuclei such as uranium, radium, and thorium.
