<u>ANSWER:</u>
The correct option is B- Qualitative.
<u>EXPLANATION:</u>
When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.
Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
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:
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.
As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.
Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.
