Sam, Josh, Megan, Danielle, and Isaac are all studying an invasive plant along the Ankh-Morpork river basin and natural areas. This plant, the Venezuelan Salt berry, can grow into a tree up to 10 meters high with a total shade cover many times this height. When one stem is cut, many more will sprout beneath the cut line to produce a tangled web of new branches. The entire tree must be cut at soil level and treated with special herbicides to prevent regrowth. The berries are small, less than 7mm in diameter, and bright red when ripe. They tend to grow in large clusters at the terminal end of branches. Each of our young scientists are testing a different hypothesis to prove how the Venezuelan Salt berry is spreading so quickly along the muddy banks of the river and into the interior. Sam observed that the most abundant species of bird, a common lark, quite enjoys the berries and eats voraciously from the clusters throughout the summer months. Josh observed that when hiking through the wooded areas, there are many areas of bear scat that are red from the abundance of berries. Megan heard people say that bees make a mighty fine honey and local people have been planting them in orchards for their apiaries. Danielle read a newspaper article which mentioned the tree was brought over from the Rim as an ornamental plant which escaped a botanical garden. Isaac believes that wind carries the berries, after they ripen and dry out on branches, across great distances in the windy, dry season. Explain how Megan would approach her observation with the scientific method to determine if she was right in her thoughts. Be details, label the steps, and provide a reasonable experiment she could use to test a rational hypothesis.

the answer

b.) bowling ball

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
