Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.
Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.
Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.
Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.

<span>Homologous structures refer to structures that have similar characteristics in terms of morphology, anatomy, genetics, and embryology yet still different when their functions are concerned. On the other hand, analogous structures are those organisms that have similar lifestyle because they live in the same habitat yet they belong in different groups.</span>
Answer
The correct sequence is given below.
Explanation:
A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)
B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)
C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)
D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)
E. Oxygen (It is the final acceptor of electrons and gets reduced to water)
DNA polymerase is the enzyme that is responsible for adding correct nucleotide pairs to new and growing DNA strands. Mismatched base pair errors will occur if this enzymes is not able to function optimally. There are other system that work DNA polymerase, these are proof reading system and mismatch repair system. Less than optimum function of these system will lead to uncorrected mismatched base pairs.
Answer: in order for a scientific investigation to be valid A hypothesis must be tested throughout a Scientific investigation that can gather evidence and support it.
Explanation: in any scientific investigation you have to have a testable hypothesis, without your hypothesis it’s not really a scientific investigation.
Hope this helped!
