Answer:
For example, the Milky Way galaxy is some 100,000 light-years across, and our closest galactic neighbor, Andromeda, is some 2.5 million light-years away. In other words, it takes light 2.5 million years just to travel from our galaxy to the one that is right next to us.

If the immune system fails to produce proteins (Antibodies) it can cause a disease. This is because our immune systems are very needed so if our immune system decides to fail to produce its proteins, our body will become overwhelmed and could possibly cause us to die! :(
Answer:
A,B and E
Explanation:
- I+: I refers to the lac repressor, the + indicates that the repressor is functional
- P+: P refers to the promoter region and the + indicates that the promoter is functional
- Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
- Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
- Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional
So based on the breakdown above:
- C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.
- D is not true because Z-, no β-galactosidase is produced.
Only A, B and E apply.
Answer:
1) G C G U A U G (C C C) (U U U) (A A C) (C G C)
2) U U A U G (C G U) (U A G) (G C G) (U U U) (A U U)
3) U A U G (G C U) (U A G) (A A U) (A A C) (C C G) (U A A)
4) U U A U G (C A A) (A G G) (G C G) (U A U) (C U U) (U A G)
5) represent codons which are groupings of 3 consecutive nucletides
Explanation:
Opposites for REGULAR mDNA base pairings are T= A and G = C, however, since it is mRNA, your base pairings change a little. G is still to C BUT Thymine (T) becomes Uracil (U) so A= U instead of A= T. So big difference between mRNA and mDNA is that Thymine changes to Uracil and vice versa depending on how the code is being translated.
Hope this helps some, please let me know if there's anything that doesn't make sense
Answer:
The correct answer from the options is Growth.
Explanation:
There are seven basic characteristics of life which separate living things from non- living things.
Growth is one of the characteristics which separate a living thing from a non- living thing. The plants use essential macromolecules for growing. The fire will not have macromolecules to grow. Hence, growth is the option that is correct.
Other options like defined boundary are incorrect because both plants and animals have a defined boundary.
