The correct answer is A.
I hope I've helped!
In physical science there are two types of "isolated systems"
1. Being a Physical System in which it is so far removed from other systems that it does not react with any of them.
2. Being a Thermodynamic System in which it is enclosed by rigid immovable walls of which neither mass nor energy can flow through.
I believe in this case although not stated that it would refer to a Thermodynamic System which would leave you with the only plausible answer as ENERGY AND MATTER CANNOT ENTER OR LEAVE.
None of the other answers make sense. Even if it were referring to Physical. Physical does not react with anything at all. An as you can see Thermodynamic does not allow for anything to pass through or leave.
All amino acids are structurally the same, in that they contain a central carbon atom, an amine group, a lone hydrogen at. Our DNA is contained in our chromosomes. The thing that is different about each of the 20 amino acids is the make-up of the R group
Alleles are letters that represent dominant and recessive traits.
A capital letter represents a dominant trait
A lowercase letter represents a recessive trait.
Dominant traits over shadow the recessive ones. This is known as complete dominance.
Referring to your questions let's us the alleles HH, Hh, and hh for the height of the pea plants.
But what do those letters mean?
HH = homozygous dominant (Tall)
Homo means same.
hh = homozygous recessive (Short)
Now this is different: here's Hh.
There's a capital AND lowercase letter.
This means that the plant carries the gene for tall and short plants, and can pass on either trait to the offspring.
BUT the dominant always over shadows the recessive. So Hh is a tall plant.
Hh = heterozygous (hybrid) (Tall)
You can interpret hetero meaning different.
Now I hope you're with me!
For question two it asks if a short plant can ever be a hybrid.
Referring to what I just said, that answer would be no.
Because there is no dominant trait to over shadow the recessive.
And short plants have the hh alleles, and they are homozygous NOT heterozygous (hybrid).
I hope this helps, and makes sense! If you have any questions please let me know. Genetics can be confusing.
