1. there isn't a place on earth that is safe from these tornado warning 2. get into a building or a car when this begins to strike blizzard 3. a plan of evacuation will to keep you safe during this natural disaster flood 4. can dump inches of snow on an area in a matter of minutes natural disasters 5. get to a shelter immediately when this warning is given lightning 6. get away from things that might fall on top of you when this disaster occurs earthquake

The answers would be the following:

1. Natural disasters

2. Lightning

3. Flood

4. Blizzard

5. Tornado warning

6. Earthquake

Here's more about the choices:

Natural disasters are highly unpredictable and it can happen anywhere and at anytime. There are some ways that you can predict some of the natural disasters, but the effects and the gravity of the situation can only be assessed during and after it happens. They can be extreme and loss of life can occur.

Lighting is an electrical discharge that happens when an imbalance occurs between the clouds and the ground and more often, within the clouds itself. There are about 2,000 deaths caused by lightning a year in the world.

Floods can be due to nature but it can also be caused by man. An evacuation plan is a must when it comes to flood-prone areas. Overflowing of rivers is an example of a natural disaster but pollution and deforestation due to activities of human beings also triggers a flood.

Blizzard is a sustained and sever snowstorm. To count as a blizzard winds should be at least 35mph and rage on for an extended period of time. What makes it so dangerous is that snowstorms prevents travel so it is hard to escape from one. Visibility is almost zero, so it would be dangerous to travel when you are caught in one.

Tornado warnings is an alert given to the public when a tornado has already occurred, or a funnel cloud has been spotted. The warning is often in the form of sirens, warning residents near-by to seek immediate shelter. Some residents have their own shelters, while others retreat to the nearest one they could find.

Earthquakes are also natural disasters that are less predictable than others. When an earthquake occurs, it is advisable to evacuate to an open space. The heavy and strong shaking of the ground can easily overturn objects, which could fall.

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.
