Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n
If you must leave an injured or ill athlete unattended to get additional help, and you do not suspect an injury to the head, neck or back, then you should ask not to move while going for help, either by calling 911 or looking for someelse to help, once contacted help return immediately with the injured person and check that no threat has appeared to his life and provide care while the help gets there.

Explanation: Traits usually die off when they are unneeded by the organism, or if the trait causes harm to the organism's survival. Through natural selection, over time, the organisms with the best combination of traits for its survival will become the dominating species, and those with weaker traits may not survive long enough to pass off their traits to future offspring.
<h3><u>Answer;</u></h3>
B.) Earthquakes are the most common cause of tsunamis
D.) A volcanic eruption releases hot gases into the air.
E.) A single hot spot can form multiple volcanoes due to plate motion.
<h3><u>Explanation;</u></h3>
- <em><u>The Tsunamis occur as a result of violent movement of the seafloor that is associated with the impact of the earthquakes, landslide or the lava entering the sea among other factors.</u></em> <u>Earthquakes are the common cause of tsunamis at 72 percent.</u>
- <em><u>A volcanic eruption releases hot gases into the air. During a volcanic eruption gases that are initially dissolved in magma are released into the atmosphere. </u></em>Water vapor is the most abundant gas released from a volcanic eruption.
- <em><u>A hot spot refers to an area in the mantle from which heat rises from deep in the Earth as a thermal plume. This high heat and low pressure in the tectonic plates causes melting of the rock which rises through the cracks and erupts.</u></em> A single hot spot can form multiple volcanoes due to plate motion
