Agroup of 4 students want to design an experiment in an effort to support the hypothesis, “sunlight is needed for the normal healthy growth of plants.” each student presented a possible experiment. student #1: purchase 20 plants. plant 10 of the plants in 3 cups of soil and place all of the cups in the sun. take the other 10 plants and put them in 2 cups of soil, then place this group in the sun under a box. observe and document changes. student #2: place 10 plants outside in the sunlight. place the other 10 plants outside under a box. plant both in the same amount of soil and provide all with the same amount of water. document observations. student #3: place 20 plants in front of a window. give all of the plants the same amount of water and the same type of soil. observe plants for any changes. student #4: obtain two seeds. place one seed outside and one on an inside window sill. observe and document which seed sprouts the fastest. which student provides the best reason for choosing his or her experiment to test the hypothesis?
a.
student #4: “seeds grow into plants, so if the seeds are healthy, then the plants will also be healthy.”
b. student #3: “all of the plants were placed in the sun and kept under the same conditions.”
c. student #2: “included are 10 plants that were not placed in the sun.”
d. student #1: “the plants will react differently in different amounts of soil”

d. planting trees

the trees take in carbon to make oxygen.

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.
