1. What qualifies a fossil to be used to find the absolute age of rocks? if the plant or animal existed for a limited period of time and in a wide area

if the plant or animal existed for a long period of time and in a wide area

if the plant or animal existed for a long period of time and in a small area

if the plant or animal existed for a limited period of time and in a small area

2. Which quantity helps determine the absolute age of rocks and fossils?(1 point)

the difference between the amounts of carbon-12 and carbon-14

the difference between the number of protons and neutrons in carbon-14

the ratio of protons to neutrons in carbon-14

the ratio of carbon-12 to carbon-14

3. Which statement best describes why most individual organisms never fossilized?(1 point)

Chemicals that fossilize organisms are rare.

Only organisms with hard parts fossilize.

Only organisms that lived in the ocean fossilize.

Conditions for fossilization are rare.

4. The half-life of carbon-14 is 5,700 years. A certain sample of wood has 20 grams of carbon-14 when it is alive. How many grams of carbon will it have after 5,700 years?(1 point)

40 grams

2 grams

10 grams

5 grams

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.
