describe the situation of world population​

Answers

Answer 1

Answer:

In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7,800,000,000 people as of March 2020.It took over 2 million years of human prehistory and history for the world's population to reach 1 billion,and only 200 years more to reach 7 billion.

Explanation:

The world population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was near 370 million.The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975 – peaking at 2.1% between 1965 and 1970.The growth rate declined to 1.2% between 2010 and 2015 and is projected to decline further in the course of the 21st century.

The global population is still increasing, but there is significant uncertainty about its long-term trajectory due to changing rates of fertility and mortality.The UN Department of Economics and Social Affairs projects between 9-10 billion people by 2050, and gives an 80% confidence interval of 10-12 billion by the end of the 21st century.

Total annual births were highest in the late 1980s at about 139 million,and as of 2011 were expected to remain essentially constant at a level of 135 million,while deaths numbered 56 million per year and were expected to increase to 80 million per year by 2040.The median age of the world's population was estimated to be 30.4 years in 2018.

Why might a person request a generic
name drug from a physician rather than a
a brand-name drug?

Answers

These similarities help to demonstrate bioequivalence, which means that a generic medicine works in the same way and provides the same clinical benefit as the brand-name medicine. In other words, you can take a generic medicine as an equal substitute for its brand-name counterpart
To save money. Generic medications function in the same prescribed manner as the brand name. The difference is that when the pattern for the brand name medicine expires, other manufacturers can produce a generic alternative at a lower price. Also, in the US most insurance companies will not pay for brand name medications when a generic alternative is available

What’s the difference between ambulatory Aid and Manual conveyance?
this has to do with the stabilization of an injured athlete.
do not copy and paste from the internet or give a fake answer. thank you.

Answers

Answer:

While I do not know the difference, I do know what both of them are, hope this helps! It does sound pretty similar to online things but this is what they are.

Ambulatory Aid is a type of medical care provided on an outpatient basis. Where they do a diagnosis, observation, consultation, and treatment.

Manual Conveyance is a condition in which there is insufficient fluid available in the circulatory system resulting in a reduction in cardiac output.

Manual conveyance is utilized when an injured athlete cannot walk and needs support or transfer to a safer location. Whereas, ambulatory aid is used when the athlete can still walk or move with assistance.

Both "Ambulatory Aid" and "Manual Conveyance" are techniques used to carry the wounded person in the context of stabilizing an injured athlete. They vary, though, in terms of how much help they offer and how much mobility the injured person is given.

(1) Ambulatory Aid: Ambulatory aid is the term used to describe giving assistance and support to a wounded athlete who is still able to walk or move around somewhat. In this scenario, the athlete is still able to carry weight on the injured leg or body part, although assistance may be needed to keep their balance and stability. Crutches, canes, and walkers are examples of ambulatory aids. These tools support the athlete when they walk and help keep weight off of the damaged area.

(2) Manual Conveyance: Athletes who are wounded and unable to walk or carry their own weight can be manually assisted or carried.

Athletes who sustain more serious injuries might not be able to use ambulatory assistance and need to be transported right away to a safer area for additional assessment and medical care. In such a situation, trained individuals, such as trainers, teammates, or medical experts, may need to carry or support the injured athlete to a stretcher or another secure area.

When an athlete's condition prevents them from walking or using ambulatory assistance, or when their injury is more significant, manual transportation is often used. To prevent aggravating the injury, it is crucial to handle the injured person carefully and lift them using the right procedures.

Hence, manual conveyance is utilized when an injured athlete cannot walk and needs support or transfer to a safer location. Whereas, ambulatory aid is used when the athlete can still walk or move with assistance.
