Yes, yes, go on ! The nearest star to us that's outside of our solar system
is 4.2 light years away. So when we see that star, we're not seeing it as
it is, we're seeing it as it was 4.2 years ago. And all of the other stars
are much farther away from us than that one is. We have detected
galaxies that we're not seeing as they are now, we're seeing them as
they were 13 billion years ago !
The moon is about 240,000 miles away from us. When we look at the
moon, we're not seeing it as it is, we're seeing it as it was 1.3 seconds ago.
The refrigerator in your kitchen is about 12 feet from you. So when you
look at the refrigerator, you're not seeing it as it is. You're seeing it as it
was 0.0000000122 second ago.
It takes TIME for light to travel from one place to another.
Answer:
cell membrane- controls what goes in and out of a cell
cell wall- protects DNA and other organelles inside a cell
ribosomes-makes and produces proteins
The momentum after collision is given by (m1+m2)v where m1 is the mass of car A, m2 us the mass of car B while v is the common velocity after collision.
Therefore, momentum=(2000+4000)5=30000kgm/s to the right.
D. Adding another base pair will re-arrange your DNA sequences and cause an insertion mutation. This will make your codons group of differently, and possibly give you a BAD mutation. However, sometimes the codons still make the same proteins as its supposed to, the mutation will NOT affect you.
Example:
THE BIG FAT CAT ATE THE RAT
Now, if i were to add a letter (X) to this and make the letters group up in three aka the codons:
THE XBI GFA TCA TAT ETH ERA T
As you can you can see, adding a base pair in a DNA insertion will usually have a negative effect, specifically a insertion mutation.
