People’s choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual’s health and, if applicable, the health of others.

Answers

People nowadays try to live a healthier lifestyle. The positive and negative choices depends on some aspects. For instance, a person with a normal weight or thin can be unhealthy . Health also includes the good amount of nutrition and exercise not only the weight. A good choice a person can make is exercise more and intake good amounts of nutrition. A bad choice is not exercising and not having adequate intake of nutrition. Some people tend to lose weight by quiting some nutrients which will have a bad effect on their health since all the nutrients are important for the body and avoiding some nutrients can cause deficiency. The best thing to do is diet on calories, a type of diet from which you can eat anything(all types of food including vegetables and fruits ) but measure your calorie intake , with this a person has a higher chance of losing weight and being healthy. Exercise too is an essential factor needed for a healthy lifestyle. If a person has a lifestyle which they need to move alot(jobs including sports etc) then you can say its enough but if not a person must do exercise at least twice or more a week for better health. Quitting smoking and drugs of course has a good effect.

how does air pressure affect weather

Answers

Answer:

Hewo, Kiluawa (sorry if i spelled it wrong)

Explanation:

High Pressure

Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.

Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.

Low Pressure

On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.

Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.

In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

[HC]Read the text then answer the question that follows:Wild animals as viewed from a mountain campCamille Grant, October 2011Through my binoculars, I viewed a group of wild animals in action. A pride of lions was sleeping when a small, yellow bus pulled up beside them. Tourists on a safari were packed into the bus like sardines in a can. Armed with cameras, they invaded the lions' territory, hoping to capture the perfect photograph. The crowd leaned out the windows, hooting and hollering, until the lions awoke. When the lions moved away, the bus rolled after them, relentlessly stalking the pride. One of the lions turned and roared to protect the young. This was greeted with cheers and a celebratory honk of the bus horn. The curious visitors observed the lions' routine for an hour before moving on. Leaving a cloud of dust, the bus headed away, taking the wild animals off to disturb someone else's home.Review the following line from the text:Tourists who had paid money for a safari were packed into the bus like sardines in a can.Which statement is true?
