Answer: Fruit will not brown. Browning requires a functional enzyme.
Explanation:
Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>
Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.
If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.
Dual visual system:
Dual visual system is nothing but the different visual systems that our brain is meant to direct.
The two visual systems are
- Dorsal Stream
- Ventral Stream
Dorsal Stream:
Dorsal stream is mainly referred as a vision of action. This visual system is involved in moment by moment analysis. It is also known as where stream.
Ventral Stream:
Ventral stream is mainly referred to as the vision of perception. This visual system is meant to analyse and recognize shape and object etc. It is also known as What stream
Blindness:
Blindness is a defined as the lack of vision. Such type of vision loss can't be corrected either by contact lens or through glasses.
There are two type of blindness,
- Temporary Blindness
- Permanent Blindness
Temporary blindness is a condition where the vision of an individual vision is limited.
Permanent Blindness is a condition where an individual can't see anything even the light
Answer:
La producción agropecuaria tiene unos profundos efectos en el medio ambiente en conjunto. Son la principal fuente de contaminación del agua por nitratos, fosfatos y plaguicidas. ... Si se utilizan más métodos de producción sostenible, se podrán atenuar los efectos de la agricultura sobre el medio ambiente. I hope it helps you
Explanation:
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful
The Himalayan Rabbit sports black fur on its extremities. This is due to an ancestral trait; the Himalayan Rabbits carry “temperature sensitive tyrosinase genes” which controls fur pigmentation. The rabbit’s ancestors, which would have had to survive in the cold Himalayan environment would have, through natural selection, favored a gene that allows for a darker pigmentation. Through evolution the Himalayan Rabbit passed down the genotype for a melanin producing gene, which activates in low temperatures, changing the individual rabbit’s phenotype to fit the climate.
So your answer is choice 1
Hope this helped!
