Describe four factors that influence ocean currents.
explain how the coriolis effect impacts ocean currents.
what is the relationship between ocean currents and climate?

1.Ocean currents are actually horizontal water movements caused by many different factors or combination of them.  Some of them are:

•Wind – Strong winds (such as the Westerlies and the Trade Winds) can move the water surface causing the ocean currents.

•Water Density (the difference in water dense is due to difference in water salinity and temperature) -  more dense water will sink and that sinking water pushes the water below it up.  

•Topography of the ocean bottom - ridge in the ocean bottom moves the water upward, while valley in the ocean moves it downward.

•Coriolis Effect - refers to an internal force (Coriolis) that causes the deflection of an object in motion. As a consequence of this effect, objects in the Northern Hemisphere of the Earth are deflected to the right and objects in the Southern Hemisphere to the left.

2.Coriolis force is an internal force that acts on objects in motion and it is responsible for many weather occasions. Deflection of an object under the influence of Coriolis force is called the Coriolis effect. The Coriolis force causes the movement of objects in the Northern Hemisphere of the Earth to be deflected to the right and to the left in the Southern Hemisphere. So, there are two currents of water movements in opposite directions one in the Northern Hemisphere; the other in the Southern hemisphere and when these currents are deflected by land masses ocean currents are formed.

3.The ocean current can affect climate in many different ways. For example, warmed or cooled water carried by ocean currents can travel for very long distance. The displaced warm water will raise the temperature of the air while the cold will cool it. So, some currents take warm water away from the equator, to the poles where they influence coastal climates. On the other side colder water from the poles moves towards the equator cooling the air above and absorbing the heat.

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.
