Answer: 4 codon
Explanation:
We have two important data, that a molecule brought from Mars uses only three bases (A, C and T) and that it has 30 amino acids
Knowing that to encode 30 amino acids with 3 bases, you need to have 4 bases in your codon.
We have the possibility that having 4 bases can be encoded enough like this:
3 ^ 4 = 81.
however if we do the same procedure with 3 basic codons we will get an insufficient result
3 ^ 3 = 27
so the most likely codon number is 4
The membranes that surround and protect the brain and spinal cord are called meninges.
The major problem with using foreign cells grown in culture for transplantation in humans is the host immune system would destroy such cells.
The body of your child is shielded from external invaders by the immune system. These include poisons, bacteria, viruses, fungus, and other types of germs (chemicals made by microbes). The various organs, cells, and proteins that make up the immune system cooperate with one another. Infections like measles, mono (mononucleosis), and the flu virus can also temporarily impair immunity. Additionally, unhealthy eating habits, alcoholism, and smoking might impair your immune system.
Antigens, which are proteins on the surface of the invading cells, are used by the immune system to identify invaders. Every substance or cell has a unique set of antigens, and every person's cells include "self-antigens" that are particular to that person.

Answer:
The amount of electricity a hydropower plant produces depends on two factors: How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.
