The teeth of grain-eating animals (such as horses. are usually broad and ridged. This makes the teeth suitable for grinding and chewing. Meat-eating animals (such as lions. have pointed teeth that are good for puncturing and ripping flesh. This illustrates

Answer

A connection between

form and function as a result of natural selection

Explanation:

Carnivorous animals have long ,sharp teeth adapted to ripping, tearing or cutting flesh.

While many also possess a few molars in the back of their mouths, and sharp incisors in

the front, the most important teeth for carnivores are their long, sharp canine teeth .

Due to the natural selection of carnivorous animals in eating flesh ,the form which is the structure of the teeth happens to be the canine which are used for tearing and that happens to be the major fuction.

From the second paragraph we could see the careful relationship between form, fuction and natural selection.

explanation:

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.
