Phlebotomy is a technique in which a needle is temporarily inserted into a vein to provide venous access for venous blood sampling.<span> [1, 2, 3] </span><span> Veins have a three-layered wall composed of an internal endothelium surrounded by a thin layer of muscle fibers, which in turn is surrounded by a layer of connective tissue.
Its my pleasure to help over and out : )

Standard of living refers to the quality, and quantity, of goods and services made available to an individual for his/her consumption. This definition is a general one and is easily understood.
To improve one's standard of living, in accordance with this definition, one needs to be provided with a better quality goods & services , such as advanced electronics and gadgets, or quantity, such as producing more self-care product for consumption.
So how does this conflict with his/her environmental concerns? In order to improve standard of living, there is a few trade offs. To produce more quantity of goods & services, more resources have to be used. This might lead to excessive usage, wastage & depletion of natural resources. For example, to provide more fuel to the society, companies have to extract more & more of fossil fuel. Sustainable usage of natural resources might be a concern, since some types of resources are unrenewable e. g oil & gas.
Production of higher quality products requires advanced state of technology. In the meantime, the use of some technologies aren't exactly environmental friendly i. e it may create pollution. For example, decades ago, manufacturing shirts using traditional methods might not yield consistent results thus the invention of machine helps with increasing the quality, however, results in noise and air pollution. Another example, using air-conditioning instead of hand fan is more effective in coping with hot weather, but greenhouse gas is emitted.
This shows the conflict between environmental concern and the desire to improve standard of living in general.
Hope this helps!
Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.
Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.
The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.
Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.
Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.
Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.
Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.
