Answer:

True

Explanation:

Tobacco is consumed during smoking which contains an addictive substance called Nicotine. Nicotine exerts its effect on the body by stimulating the acetylcholine receptors in the neurons. The stimulation of these receptors stimulates another neurotransmitter like glutamate, dopamine and GABA which produce addictive effects in humans.

Since the acetylcholine is involved in stimulating the other neurotransmitters therefore true is the correct answer.

Thus, true is the correct answer.

Which of the following best describes the function of fruits? Group of answer choices
ratelena [41]

The correct answer is B. Protection and dispersal of seeds

Explanation:

In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.

RNA nucleotides form complimentary base pairs with DNA bases.  Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.

Explanation:

The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.

Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.

This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.
