1) Galaxies are groups that are made up of spinning matter and are held together due to the power of gravity. Galaxies contain stars, dust, gas, and many planets.

2) The Milky Way is a spiral galaxy and consists of billions of stars and planets.

3) Edwin Hubble invented the Hubble Sequence.

4) Types of galaxies are spiral galaxies, irregular galaxies, elliptical galaxies, and lens galaxies.

5) Scientists found that galaxies were drifting apart at speeds that were even faster than the speed of light.

Hi there!

Galaxies are groups of spinning matter pulled together by gravity. They contain trillions of planets, stars, and dust. 

The Milky Way, our own galaxy, is home to more than a hundred billion stars and even more planets. It curves in a spiral, and is where we live. 

The "Hubble Sequence" was created by Edwin Hubble. 

There are elliptical, spiral, and irregular galaxies. 

1. They found that the galaxies were actually moving apart at surprisingly fast speeds - even faster than light. Not much is known about this. 

Hope this helps!

What is a cells DNA like the books in a library
tino4ka555 [31]
Think of it this way:

DNA inside cells store all the genetic information on a person's looks, eye colour, hair colour etc. It makes them unique. The analogy of being like books in a library basically suggests that in a library there is so much information and every book is different with different knowledge... That's basically what DNA is; millions of different information things.

The phenotype of an organism is its physical characteristics, which result from the organsism's genes.
FromTheMoon [43]
What is the question ??

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
