I believe the answer for the above question is that it cannot bind to the inducer. An inducer molecules regulates gene expression, it can bind to protein repressors or activators. The binding of the inducer to the repressor prevents the repressor from binding to the operator. A super repressor is a repressor that binds to an operator and is non-iducible so it can not be removed. These are dominant because they will bind and never be removed, even if the wild type is attached to one, once it is removed the lac IS may attach and never be removed.

Fossil fuels are commercially available as an energy source.
They are very easy to find. More and more extractions of fossil fuels is going on everyday. With advancement in science and technology, the refineries and extraction procedures have improved a lot. This makes their availability even better.
Fossil fuels are also easily combustible. Most combustion engines need to be powered with little amount of fuel to produce large amount of energy. Very large amounts of electricity can be generated from fossil fuels.
Hello!
We all are very well familiar with Mendel's laws of inheritance. Just recalling Mendel's law of independent assortment that states, "alleles of different genes are inherited independently of one another".
Here we have two traits, and we want to know how the alleles of these traits will assort independently during the formation of gametes from two parents.
The two traits are:
- Flower color ( Can be purple or white)
- Seed shape (Can be round or wrinkled)
Here the alleles of the traits are represented by alphabets as:
- purple flowers: P
- white flowers: p
- round seeds: R
- wrinkled seeds: r
We have parent one as PpRr
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 1.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
We have parent two as PpRr :
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 2 as well.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
This shows that there is not restriction that the allele for wrinkled seed r will go with allele of white flower p because its recessive or allele of round seeds R will go with allele of purple flowers P because its dominant. There is no restriction when alleles are assorting into gametes and they can go randomly as per nature's choice with any one.
Hope it helps! :)
Answer:
probably natural selection but it could also be discontinous variation.
Explanation:
depends on what context is??
Absorption takes place in the small intestine. Fatty acids and glycerol are formed by digestion of lipids which diffuse through the one-cell thick cell wall of villi and into lacteals (lymphatic vessels).
