nikklg [1K]

Alcohol gives you energy is not true about alcohol. So, the correct option is (c).

As a depressive, alcohol can upset this equilibrium and have an impact on our emotions, thoughts, and behaviour. This is due in part to neurotransmitters, which are molecules that aid in signal transmission from one brain nerve to another.

Your coordination will be impaired by alcohol since it will require more mental effort to cause your muscles to obey directions. Your brain needs more time to see, comprehend, relate to, and decide how to respond to something when you drink alcohol. Alcohol has an impact on almost every organ system in our body.

Therefore, Alcohol gives you energy is not true about alcohol. So, the correct option is (c).

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with r
MA_775_DIABLO [31]

Answer:

a rat with rabbit hemoglobin genes

Explanation:

When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.

This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.

Thus by transferring to  rat ( the DNA for Hb) as the  rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.

Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been  modified to  add certain  vitamins to improve the nutritional values.

Genetically modified bananas as edible vaccines are another example
