Answer:
Improvements in medical aid technology and increasing use of computer aided design
Explanation:
- As the world's population is going to hit around 10 billion by t end of this century. All due to the increase of technological advancements around the globe.
- Such as the reduction in mortality rate, increase in fertility rates and improvements in livelihood and productive and healthy lifestyle.
- It is due to transformation in society and the economy that is brought about by the help of technology. Due to innovation and enhancement of technology has created massive waves in the life cycle of man and his surroundings.
- Medical aid is now subsidized and free treatment is now available in third world countries, such as the opening of drug centers and fair system to evaluate the use of medicine and patient diagnostics has improved a lot.
- An example of a test-tube baby for the infertility cases and the use of stem cells to treat cancer like diseases. Countries like China and India which are number one in terms of population growth followed by Indonesia and the USA are growing since the industrial age.
This is something that I used I found it when I was asking the same question myself
The correct answer is - B. large empires developed.
The mountains are a natural barrier for lot of human activities, and one of those is the formation of settlements, big countries, or empires. The creation of large empires on a mountainous terrain is extremely hard and unpractical, and there's very few cases in the human history that that has been performed well. The reasons for that is that in the mountainous regions it is hard to create a network of roads, build large settlements, and also there's lack of natural resources and food, so the people had the tendency to create small settlements, or city-states in this kind of circumstances.
The best maritime navigation maps are nautical charts. They contain topographic map details (heights of land and depths of water), locations of natural and manmade obstacles, tides and currents data, geomagnetic field data, details of coastlines and more.
Electrons.
An electrical discharge is lightning. The air around lightning may reach 30,000°C (54,000°F) in only one lightning strike! As a result of this intense heating, the air rapidly expands explosively. The expansion generates a shock wave, which develops into the thunderous sound wave.
High in a thunderstorm, ice crystals collide as they drift up and down in the tumultuous air.
As they collide with one another, ice crystals are knocked off and added to by tiny, negatively charged particles known as electrons. This divides the cloud's positive (+) and negative (-) charges. The base of the cloud becomes negatively charged, while the top of the cloud becomes positively charged with protons.
Positive charge is carried into the cloud by a powerful electric current that forms at the point where the stepped leader and positive charge collide. The return stroke is the name given to this electric current.
