Introns stands for interveningsequences within a gene.
Explanation:
Introns are the nucleotide sequences within a gene which are intervening but noncoding regions on an RNA transcript which is spliced before the RNA translation to protein
Introns do not code amino acids for protein synthesis. They break the gene sequence in the DNA strand.
The introns form a large chunk and interfere with the protein coding of exons, hence are removed by splicesomes through splicing at the splice junctions.
Improper splicing of introns lead to faulty protein formation
The Skinner box allows experimenters to test animals without having to "re-load" the experiment, allowing the trainer to reinforce the animal with <u>operant conditioning</u> trials.
Explanation:
There are a number of behavior and actions shown by a particular specie when they are placed or position inside a given environment for the Skinner box it involve a animal which was constantly attempting to get its hands on the given bait.And that is why the following actions were termed as the operant conditioning.
Answer: B:The drought decreased the grass and vegetation on the ground, leaving only vegetation on shrubs and trees above the ground. Natural selection selected for the tortoises with the domed shells and hoods.
