Answer:
The new drug will not be effective against the treatment of cancer.
Explanation:
The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.
Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
I would say energy myself, and this is because energy plays a key role in all of these. With trophic levels energy is being transferred amongst the levels. Food chain's is a map of how the energy is passed along the chain. Food web is a web of how energy is transferred, and this is why I would say energy is a keyword.
<u>Answer</u>:
Actions happens after transcription ends is "An mRNA molecule leaves the nucleus of the cell."
<u>Explanation</u>:
Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs nearer to the ribosomes, it is the formation of protein from mRNA strand. combinedly transcription and translation are referred as the central dogma of the molecular biology.
Answer:
The answer is - (B) the amount of food that is typically consumed.
Explanation -
The symptoms of anorexia nervosa and bulimia nervosa overlap at a large extent. Both are eating disorders in which the individual, affected by any of those, tries to lose weight in unhealthy manner. But there are some key differences between both the disorders.
People suffering with anorexia tend to reduce their food intake to lose weight. It includes extreme dieting and in some cases people stop eating or eat minimal.
People with bulimia continue to eat. Unlike people with anorexia they binge, or overeat large amount of foods. The repetitive cycles of binge-eating lead to self-induced vomiting or starvation which further leads to weight loss.
Whereas excessive exercise is common in both the disorders.
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
