The right answers are:
A-present in eukaryotic genomes ==> Both exons and introns
B-generally absent from bacterial genomes ==> Introns
C-part of the final mRNA strand ==> Exons
D-code for an amino acid sequence ==> Exons
E-removed from initial mRNA strand prior to translation ==> Introns
F-present in the DNA used as the template for transcription ==> Both exons and introns
In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
Answer:
The acid in the lemon juice denatured the milk proteins.
Explanation:
The important biomolecule of the living organism is protein. Proteins are made of the repeating units of the alpha amino acids that are attached together through the peptide bond.
The proteins get denatured if they are subjected to the change in the temperature conditions or the additions of the chemicals. The addition of the lemon juice that acts as the acid coagulates the protein present in the milk and results in the clump formation.
Thus, the correct answer is option (a).
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
<span>Answer: A) Dark moths had a survival disadvantage in industrial Dorset.
-----
This question can be solely answered using the data you're given! The graph is broken down by place, and then moth type.
In forested Birmingham, the green bar for the light moth is much higher than the orange one for the dark moth. That means the light moth had a survival advantage (eliminating option D) and the dark moths had a survival disadvantage (eliminating option C).
In industrialized Dorset, the green bar for the light moth is much lower than the orange one for the dark moth. That means the light moths were at a survival disadvantage (eliminating option B). The dark moths were are a survival advantage, but option A says "disadvantage," which is clearly wrong! That makes A your answer.
