Help with this, don't even DARE waste my time just to get the points. (sry im upset bc someone just did that)
Your choices should be of relative importance during the time, and not in the long term. Remember, if you help people long term, and the short term dies, then most likely the long term people will die as well.
In the excerpt, it shows that there is enough drugs for 5 groups of people. It is also stated that 15% of the population will die. Note that "will" means necessary, which means they cannot be healed at any point of time.
Young children between birth and 5 years: Those who were borned during sometimes have a better immune system against the disease (as seen in many past instances), as their body has grown accustom to it. However, they are also the group with the highest risk. Their autoimmune system has not developed fully to be able to fight off the disease if it really takes into effect. As the ones that will be part of the next generation, they should receive the dose.
Public Servants like the Police and Fire Department: These are the ones who will have the most human interaction, especially during a high infection state (in which people will be quarantined like we are). Because of this, they should also receive their dose, as their human interaction per day-to-day basis is higher than most of us.
All Adults between 20 and 40, determined to be the highest risk for severe symptoms: Adults who are between 20 - 40 are at the prime of their age, and generally would have the strongest immune system. However, note that these people are located in the highest risk of symptoms. Remember, viruses can evolve, and so if those who are at their peak immune system and are those who most likely would travel around (and most likely not follow government orders of isolation) would have not only the highest chances of infection, but also the highest chances to spread the infection.
Utility industry employees: Utilities such as water, electricity, as well as plumbing, etc. are essential in being kept in order for people to continue to stay at home. This also means that there must be people to keep it in order and running. These people are essential in continuing the way of life for the people.
Food Industry employees: Everybody needs to eat (as well as drink), and there must be a dedicated source for such. This means while they may be able to set up a way to help isolate the people to safer distances, they should not close down. Remember, food, utility, and water make up the foundation of what is important for a human.
As for what the other groups would have to do to prevent the disease, they should stay isolated as much as they can, and to wear disposable gloves and masks when they go outside. They should also wash their hands as much as they can, and avoid to touch their mouth & face with their hands when possible. Avoid contact with others when possible. Work that can be done at home should be moved to home/online.
Possible death of the 5%:
Infants: While they may develop immunity in the beginning stages, they are also the ones that will not have developed immune system. This puts them in a hazardous yet safe place, which is why they get the cure.
Healthcare workers: Healthcare workers will be knowingly exposed to the disease. However, as they know they have a high chance of being exposed to it, they can take the necessary precautions to avoid coming in contact with it, something other groups cannot. However, I feel like the Healthcare workers should have fallen under the umbrella of Public Servants, but since it does not, I will include it here.
Any of the Employees: Employees are employees as they need the steady income from somewhere. As many may be living pay check to pay check, they may feel the pressure build up when they do not work, and may force themselves to disobey government orders and go work. They will have a higher chance to be exposed to the disease, and therefore, in turn, have a low-medium to high chance of being exposed and die of the disease.
High risk areas: They are high-risk for a reason, and so they will have a higher chance of not only contracting, but with failure of noticing the symptoms, to die of it as well.
As for the other groups, I do not have the room to give out exactly why they should stay at home. However, for your job, you can essentially write that their jobs are not essential in keeping humanity alive. Those who can will continue to work through home and the internet or other means, while the others will risk too much just to work. Those jobs that are not essential to meeting human needs or essential in finding the cure for the disease should stop at once.
What would happen if the distance of a planet from the Sun was doubled?
Answer:
Hey! Here are your answers!
1) The Earth would make a double orbit * in terms of time duration of 365.25 days * meaning there'd be about 730.5 days in a year ( a leap year therefore would be every 2 YEARS )
2) Because SOLAR RADIATION (light and heat) takes about 8 mins to reach Earth, this would be double to 16 mins
3) The planet as a whole would cool down significantly to the extent that life cannot exist!
Explanation:
HOPE THIS HELPS!!
According to Kepler's third law, T2 R3, the cube of the mean distance between the planet and the Sun (R) and the square of the time period (T) are exactly related. As a result, the planet's orbital period lengthens by a factor of two.
How does the distance of a planet from the Sun affect it?The orbital period increases and the gravitational pull decreases with a doubled distance from the sun. Depending on how far away from the Sun a planet is, it will have a different orbital speed.
A planet moves more quickly and experiences a stronger gravitational attraction as it gets nearer to the Sun.
It moves in its orbit more slowly the further it is from the Sun because of the Sun's weaker gravitational attraction.
Therefore, the planet's orbital period lengthens by a factor of two.

Please help! What can be concluded from this graph?
Answer:
i believe the answer is C
Explanation:
The conclusion from this graph is the enzymes lowers the energy of activation for this reaction. Therefore, option (C) is correct.
What do you mean by activation energy?Something that reduces the activation energy is called a catalyst. An enzyme is its biological name. Without being consumed, the catalyst speeds up the rate of the reaction.
By reducing the amount of energy required for reactants to combine and react, enzymes typically reduce activation energy. For instance: Reactants are brought together by enzymes so that they do not have to move around until they randomly collide.
Removal of reactants from the solution state, also known as desolvation. weakening the bonds between the enzyme and the reactants.

BY USING FOREST WISELY;
It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;
1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.
2) Those trees of the world make up of portion land species by more than forth or fifth portion.
There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as
hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth
Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.
COMMUNITY CONSERVATION;
It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.
These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.
There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as
Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.
The article 'By using Forest Wisely' can be summarised as:
People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem. The trees produce oxygen and they made up at least a quarter of the world population.The trees occupy the fourth or fifth portion of the land organisms.In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die. The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available. Trees are required for manufacturing important materials.The article 'Community Conservation' can be summarised as:
In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating. The humans occupied the space to practice farming and make houses. The population of the gorillas was disturbed and diminished. The hunting of gorillas by poachers was also reduced. The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife. Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.

When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If
an object is slowing down, where is the energy going? (Check all that apply)
The potential energy could be increasing, like a ball thrown into the air.
The kinetic energy could be lost to friction or airfmsistance.
The ball could be returning to its natural resting state.
Due to the conservation of energy, the kinetic energy must stay the same.
Please help
When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?
1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.
2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.
3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.
4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.
