Bogdan [553]

Answer:

Bathypelagic Zone

Explanation:

This zone occurs above the Abyssopelagic zone and below the Mesopelagic zone. The zone is dark because little light reached this region. Only a small proportion of the higher frequency visible light (red light)reaches this region. The sea creatures in this region will be predominantly back or red in color.

PSYCHO15rus [73]

Answer:

Answer explained

Explanation:

a. Overexpression of Axl receptor tyroxine kinase correlates with the decresed patient's overall survival and hence it's inhibition is under process.

AXL TKI BMS777607 treatment increased AXL protein levels after 24 h as observed by Western blot and flow cytometry analysis. Mechanistically, this inhibition-induced AXL cell surface accumulation was neither associated with epigenetic modifications, nor altered transcriptional and translational regulation. Hence this later increased the glycosylated protien abundance in kinase dead mutant. The kinase function blockaging resulted in impaired internalisation which finally incresed the level of proliferation.

An alternative technique may exist in linkage of Axl Tkl to a degradation machinery recruitment unit .

b. Mendelian disorders like cystic fibrosis results from error in the given DNA sequence which can be autosomal dominant and recessive both and also X or Y linked. Mutated gene results in the Mendelian disorders. Whereas in cancer there can be mutation or proliferation of the given cells in a specific area. In cancer cells there is 2.5 times more the mRNA present while 6.2times the DNA and hence the detection and diagnosis automatically becomes difficult as in Mendelian disorders only single sequence needs to be studied at a time .

Feliz [49]

Answer:

Change in food source.

Explanation:

If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.
