Answer:
b. The enzyme and substrate would be stuck together.
Explanation:
Enzymes are proteins whose active site binds to specific chemical reactants (i.e., substrates), thereby forming a complex that is similar to the interaction between a lock and its key. This active complex lowers the energy of the reaction and promotes a conformational change in the substrate to break down it into multiple products. When the enzyme contains mutations in its active site, the ability to bind the substrate is altered. In this case, the enzymatic reaction can't occur because the interaction enzyme-substrate doesn't produce an active complex.
Answer:
A. DNA is transcribed into RNA, which is translated into protein
Explanation:
<span>Two types of macromolecules: nucleic acid and protein.
Chromosomes are how the DNA is stored so they primarily contain nucleic acids. In addition to properly organize and condense the DNA, proteins are required. These include histones and other proteins.</span>
Answer:
1. Mutation- increase genetic variation
2. Selection- may increase, decrease or maintain genetic variation
3. Genetic drift- decrease genetic variation.
4. Gene flow- may increase or decrease genetic variation
Explanation:
1. A mutation refers to the changes in the DNA in an organism. The mutation of genes in DNA produces new adaptive features to evolve which increases the genetic variation of the organisms.
2. The natural selection favors the species which are best suited to live in that natural conditions. The natural selection, therefore, may increase or decrease the variation in a population.
3. Genetic drift is the phenomenon occurs due to random event which changes the gene pool of the population. When the genetic drift phenomenon is observed than the genetic variation of that population usually decreases.
4. Gene flow is the phenomenon in which the gene pool changes die to immigration and emigration. Therefore the phenomenon may increase or decrease genetic variation.
The answer is Desalination. Desalination is the process of removing minerals from salt water. Most ocean-water consumption and supply are most likely to be very particular in this places like USA, Europe, Africa and UN. Desalination depends on the capacity and facility of the place.
