The ecological footprint is a general assessement of the population while the ecological footprint per capita means the ratio a country's per capita Footprint to the per capita biological capacity available on Earth.
<h3>What is an Ecological Footprint?</h3>
This is best defined as the impact of human activities which is measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
The importance of Ecological Footprint is due to the fact that it does measures the biologically productive area that are needed to provide for everything that people demand from nature such as fruits, vegetables, meat, fish, wood, cotton, fibres, as well as absorption of carbon dioxide from fossil fuel burning and space for buildings and road.
In essence, the ecological Footprint assess how fast or quick the people consume resources and generate waste compared to how fast nature can absorb our waste and generate resources.

Protective systems are methods of protecting workers from cave-ins of material that can fall or roll into an excavation, or from the collapse of nearby structures. As mentioned in earlier chapters, if an excavation is less than 5 feet deep, OSHA does not require a protective systems unless the competent person sees signs of a potential cave-in. (It is important to remember that a wall collapse in a trench four and 1/2 feet deep can still have serious results!) For trenches between 5 feet and 20 feet deep, shoring and sheeting, shielding, sloping and benching are all acceptable protective measures. It is up to the planners of the construction project and the competent person on site to determine which systems will work best. If an excavation is greater than 20 feet deep, a registered professional engineer must design the protective system.
Shoring systems are structures of timber, mechanical, or hydraulic systems that support the sides of an excavation and which are designed to prevent cave-ins.Sheeting is a type of shoring system that keeps the earth in position. It can be driven into the ground or work in conjunction with a shoring system. Driven sheeting is most frequently used for excavations open for long periods of time. Another type of sheeting, in which plates or shoring grade plywood (sometimes called Finland form) is used in conjunction with strutted systems such as hydraulic or timber shoring. These strutted systems are also referred to as active systems. The most frequently used strutted system involves aluminum hydraulic shoreswhich are lightweight, re-usable and installed and removed completely from above
Explanation:
1. Employed as she was working before the holidays.
2.No, as people are considered employed if they did any work at all for pay or profit during the survey reference week.
3.Yes, as she won't be getting any pay or profit.
4.No, as to be counted as 'unemployed' you will have to be looking for work, or currently available to work. But, she is working as a substitute.
5.Yes, because she will have to look for a job.
6. I'm not sure about that one sorry
7.Yes, because he won't be getting pay or profit.
8.He will be considered in the labour force. As he won't have a job or not looking for one.
9.Focusing on school, have no time. etc.
10.That question is for you.
Answer:
Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise
Explanation:
The following that demonstrates how aging can be influenced by heredity is "Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise"
Telomeres are known to be pieces of junk DNA which are usually found at the end of end of chromosomes. The length of telomeres shorten with age.They become shorter and shorter and gets to a point when the cells cannot divide without losing some pieces of DNA. When it shortens, it affects lifespan and health of an individual.
According to the genetic theory of aging, it is seen that genes determine lifespan.
Studies has revealed that exercises helps to lengthen telomeres and also helps the heart and lungs to function well.
