Distillation is one of the processes that are used in the laboratory to remove impurities from substances. Distillation employs the differences in the boiling points of two liquids to separate them. The distillation apparatus must have an opening to the atmosphere at an end in order to avoid developing a dangerously high pressure within the system when heat is applied.<span />
Answer:
Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.
The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called stem cells.
Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body. However, this definition has been recently complicated by the existence of distinct cellular states that display these features.
There are two types of pluripotent stem cells :
- Embryonic stem cells (ESCs)
- Induced pluripotent stem cells
Embryonic stem cells are derived from the inner cell mass (ICM) of pre-implantation embryos and can be indefinitely maintained and expanded in the pluripotent state in vitro. Pluripotent stem cells can also be obtained by inducing dedifferentiation of adult somatic cells through a recently developed in vitro technology, known as cell reprogramming.
Similarly to Embryonic stem cells , Induced pluripotent stem cells can be expanded indefinitely and they are capable to differentiate in all the derivatives of the three germ layers.
Another intriguing features of being pluripotent is its reliance on gene expression heterogeneity.

Holism.
Explanation:
Anthropology is the branch of scientific studies that deals with study of human development in terms of body structure, culture,social behavior and language.
Biological anthropology deals with the evolution of man on the basis of biological structures.
Cultural anthropology deals with the evolution of different culture and society.
Social anthropology deals with the evolution of various societies from the time when man was totally uncivilized.
Linguistic anthropology deals with the study of evolution of languages.
In short anthropology deals with all the aspects of human beings. This commitment of anthropology to studying the entire picture of human life,including culture,biology,history and language is termed as Holism.
Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.
<h3>What are the processes of biomass production in generation of gas</h3>
Biomass is converted into energy through various processes such as Direct combustion means burning to produce heat. Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels while on the other hand, Chemical conversion is a process to produce liquid fuels.
So we can conclude that thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.
