Downward pull of gravity can cause materials to move from areas of high elevation to areas of low elevation. The force of gravity can cause rocks and glaciers to move down mountain slopes, and also cause rivers to flow toward the oceans. Landslides are the sudden mass erosion of rocks down a hill.
Bacteriophages most frequently have which sort of morphology, when bacterial genes are transmitted from one bacterium to another by a virus.
<h3>What does a bacteriophage look like morphologically?</h3>
The best method for examining the morphology of bacteriophages is electron microscopy. It has a polyhedral head, a short neck and collar, and a straight tail. It is tadpole-shaped. The head is 950 x 650 in size and has a bipyramidal hexagonal form. A membrane (capsid) that is about 35 thick encloses the contents of the head.
<h3>What kind of bacteriophage is most typical?</h3>
Assphages are a large and common family of tailed bacteriophages that are thought to infect bacteria belonging to the phylum Bacteroidales. Members of this viral family have never been isolated in culture and are still poorly understood despite being present in up to 50% of people and accounting for up to 90% of human gut viromes.

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.
