Through genetic engineering, scientists developed a new technology that combines two different fragments of DNA from two different organisms to create new targeted trait, what is this new technology?
The process of changing or altering the genes maybe summarized in four basic steps, which among the following steps come first?
The second basic step to genetic engineering is:
The third basic step in genetic engineering is the process of combining fragments of DNA from different sources, this process may also be called:
Once the new DNA, is formed, which is a combination of fragments of DNA from different sources, it is already termed as:
Lastly, the new DNA produced through genetic engineering will be introduced to a host cell to see how it will code for a new protein. What concept in biology is highlighted in this step?
Living cells follow a specific hierarchy of command in directing the traits of the individual. What will happen to the new individual cell as a new engineered DNA was introduced to it?
What application of Recombinant DNA technology is used by farmers in order to produce a better yield in crops, a better quality of crops, and easier pest control?
In the field of medical advancement, one of the earliest developments in the field recombinant DNA technology is the production of _______, which is mainly used in the treatment of diabetes.
What bacteria is an alternative for rennet which is used in the cheese production industry?
What mold is also known as kojic mold which is genetically improved to be used in enhanced production of kojic acid which has many applications in the cosmetics and beauty industry?
Name the era, which is divided into three periods, and is considered as the age of reptiles.
The period on a geologic time scale which is considered as the explosion of life:
The current epoch upon which organisms of the earth are living.:
Which among the following best describes the Cenozoic era?
How will you describe the Geologic Time Scale?
What period is known as the age of fishes?
How will you` describe the Triassic period?
How many periods are under the Cenozoic era?
Evolution is brought by the change in the gene frequency of a population over the next generation, which among the following is considered the change in gene frequencies because of chance processes?
The movement of genes or certain traits into or out of a population, that is immigration or emigration, is identified as what type of mechanism causes a change in the gene frequency of a population?
Name the type of mechanisms of evolution that takes place because some female/male species prefer to interbreed with mates that have certain or predetermined qualities.
Identify the mechanism of evolution that resulted from the deletion, insertion, substitution, or inversion of DNA because of radiation or copying errors.
Nature “selects” which organisms will be successful.
What type of mechanism of evolution is this: some species exhibit intra-sexual competition leading to the preservation of genes of those successful organisms?
A cause of change in the gene frequency of some animals and crops because of humans’ selective breeding or cross-pollination activities on these said organisms:
The following are the evolutionary reasons given by Wallace EXCEPT:
Show how the patterns of descent with modification be described in terms of a flow chart.
Patterns of descent with modification showed that all organisms came from a single ancestor which through the passing of time and after different variations have birthed to a new species that will also tend to bring new divergent species.
Patterns of descent with modification happens mainly because of this mechanism of evolution:
He is the first person to significantly discovered how one new species can be a result of modification from a single original species.
He reasoned how species may change through continuous use and disuse of its trait or organs.
One of his main studied specimens are the birdwing butterflies which helped him to also theorized on the divergence of species from a single original species, he reasoned that struggle for existence of the organisms lead to such process.
His work prompt Darwin to also publish and communicate Darwin’s theory on the speciation of organisms on Earth.
What book did Charles Darwin wrote and made him as the father of evolution?
What Principle did Lamarck theorized to be the reason why giraffes developed longer necks?
DNA of the life-forms on Earth are almost universal and seem to be templated from one original source, this line of inferring can be based from what evidence of evolution?
Exactly different organisms such fish and humans may have resemblances during the early stage of their development and will lose some key likenesses as they grow in later stage of development, which among the following is the line of evidence and field of study that underlie the said concept for evolution?
Preserved bodies of cave dwelling man from cold and icy places suggested that humans look different in the past, what evidence of evolution is used?
Identify what evidence of evolution is used: vertebrate animals such as humans, chickens and fish have gill slits and tails during their embryonic stage.
Boa constrictors, a kind of snake has a remnant of what appears to be rudimentary hindlegs, what type of body structure are these?
These body structures indicate that organisms descended from a close common ancestor.
Fox and polar bears which are distant relatives both developed white colored fur to adapt to the snowy environment where they habituate. These body structures are identified as:
This is the study of body structures of organisms to compare and infer evolutionary links.
What subdivision of systematics employ techniques and methods to determine phylogeny?
Systematics aim to put organisms into a classification that represent their evolutionary relationship, which method is preferred by systematists to represent the said classification?
What evidence/s can be used to identify the difference of one taxon from other taxa to be appropriately classified in accordance to their phylogeny?
Which part of a cladogram represent a hypothetical younger common ancestor before branching or new speciation occur?
A rooted cladogram represents a common ancestor with all of its descendants, which of the following is needed to serve as a reference group to identify the common ancestor before branching for the set of organisms occur?
In taxonomy, there is a hierarchy of grouping organisms, which among the following is the greatest and most general classification of organisms?
