Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
Answer:
Evelyn's ______ is the practical use of solar power in a vacuum cleaner that is designed to effortlessly vacuum clean the floors of on-the-go and elderly consumers.
A) product idea
B) product concept
C) product image
D) prototype
E) promotional product
Answer: B
Explanation:
Evelyn's product concept from the above was born from thorough research to determine best quality and best performance product for her target market- her on-the-go and elderly consumers. The product concept is a very important concept in marketing that deals with maximizing product features to suite target market, therefore reaching market potential.
Answer:
"<em>The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is</em><em> higher</em><em> because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration.</em>"

A spade placed in the fire turns hot.
Explanation:
Answer: b. Acetyl Co-A
Explanation:
Acetyl CoA produced through pyruvate, amino acids, and fatty acids are oxidized in the Krebs cycle in CO2, obtaining as products NADH, FADH2 and GTP (ATP). Parallel to this oxidation, the Krebs cycle produces compounds used as precursors for biosynthesis. As it is a cycle, an oxaloacetate molecule could, in principle, oxidize an amount indefinite of acetyl CoA. Acetyl-CoA is formed from the oxidative decarboxylation of pyruvate, sequentially performed by pyruvate dehydrogenase -PDH (complex multi enzymatic of 3 enzymes), in the mitochondrial matrix.
