1.what is the metric system? why might scientists prefer using metric units rather than feet or inches? 2.how can you measure the volume of a solid that does not have a regular shape? what property must the solid not have for your method to work? 3.water freezes at 32 degrees and boils at 212 degrees on the fahrenheit temperature scale. compare the size of a degree of the fahrenheit scale to the size of a degree on the celsius scale.

Hey there!

1.The metric system is a decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10.Metric units of length are easy to use because they are based on multiples of 10.

2.You can immerse the solid in water and measure the volume of the water displaced. The solid cannot dissolve in water.

3.A degree on the Fahrenheit scale must be smaller because there are 180 degrees between freezing and boiling as compared to 100 degrees for the same range on the Celsius scale.

Hope this helped @ShaggySnaps

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

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.
