Anthropology

From metabolic oxygen demand of our nutrient intake, it is estimated the amount of oxygen demand of a human is in the order of 400 Litre per day. The figure may be different base on activity performed during day.

Serbians typically have fair to olive skin, dark hair, and eyes. They often have a Slavic and Balkan facial structure, with strong jawlines and high cheekbones. Height and build can vary, but a common trait is a sturdy and athletic physique.

Homo sapiens have a highly developed brain with complex cognitive abilities, including language, abstract thinking, and problem-solving skills. They also have a more advanced capacity for social cooperation and cultural transmission. Additionally, Homo sapiens exhibit a wide range of diverse behaviors and adaptations that have allowed them to inhabit and thrive in various environments across the globe.

A predicted consequence of increased carbon dioxide concentration in the atmosphere is an increase in global temperatures, as carbon dioxide is a greenhouse gas which captures and retains the sun's heat.

The oxygen enters the body via the nose and mouth then travels down the trachea ( wind pipe ) then breaks into two bronchi (the bronchi splits the air into each lung) which then branches into lots of bronchioles which end in lots of alvioli

Carbon dioxide is released into the atmosphere through natural processes like respiration, volcanic activity, and decomposition, as well as human activities such as burning fossil fuels, deforestation, and industrial processes. These sources contribute to the increase in atmospheric CO2 levels, leading to global warming and climate change. Reducing emissions from these sources is important for mitigating the impacts of climate change.

Some examples of syncretism in Christianity include incorporating pagan festivals and symbols into Christian holidays (such as Christmas and Easter), blending indigenous spiritual practices with Christian rituals in some cultures, and combining elements of different Christian denominations into new forms of worship.

Modern humans belong to the group of hominids known as Homo sapiens.

It is because that feature is constantly displayed in cinema, television, print media, greeting cards, etc. I have to say Americans are probably the worst for this. They have a tough time accepting anything that isn't just like they expect it to be.

The smallest ethnic group in the world is believed to be the Sentinelese tribe, an indigenous group living on North Sentinel Island in the Andaman Islands of India. Due to their isolation and protection from outsiders, their exact population is unknown but estimated to be very small, likely fewer than 100 individuals.

Life originated in the oceans over 3 billion years ago. The oceans were full of many organic molecules and this is where life assembled. According to modern evolutionary theories and the studies of cell development, many scientists have concluded that life originated as small prokaryotic life forms and as bacteria under the water. Some of these cells later evolved into larger organisms, such as fish, and some developed legs where they traveled on land and created terrestrial life.

The human race refers to the collective group of individuals that belong to the species Homo sapiens. It is characterized by shared physical traits, such as bipedalism and large brains, as well as cultural characteristics like language and complex societies.

When a cell doubles in diameter, the cell membrane surface area is multiplied by four. This is because the surface area of a sphere (or a cell in this case) is proportional to the square of its radius.

In my knowledge, the microorganisms lived first on earth.

Behavioral genetics studies what role genetics plays in both animal and human behavior. This is different, though somewhat a part of, genetics which studies heredity. Behavior geneticists only look at behavioral traits that may be passed to offspring and often deal with studies related to ethology and psychology rather than inheritance of all characteristics as in genetics.

A mountain range can both protect and isolate a civilization. The natural barrier of rugged terrain and high elevations can shield the civilization from outside threats, while also limiting movement and communication with other regions.

We all started out in Africa. We are ALL Africans by origin. Humans migrated out of Africa very roughly 100,000 years ago. As we spread across the planet, natural selection helped us adapt to different climates and different needs. The National Geographic Society has lots of excellent material on this.

Biologically, there is no scientific basis for the concept of "pure races." Human populations have mixed and intermingled over thousands of years, leading to a diverse range of genetic markers across all groups. The idea of distinct and separate races is a social construct, not a biological reality.

foragers rely on unpredictable food sources in their environment, leading to uncertainty in food availability. This uncertainty often results in fluctuations in population size, with periods of abundance followed by scarcity. Additionally, foragers typically have high energy demands due to their active lifestyle, which can limit their ability to invest in reproduction and lead to lower population growth rates.

Sexual dimorphism in humans is likely to stay relatively constant over time, as it is influenced by genetic factors and evolutionary history. However, various external factors such as changing societal norms and cultural practices could impact the expression of sexual dimorphism in different populations.

Anthropology and sociology both deal with society. The only difference is that social anthropology mainly considers small groups and their culture, but their area of study is basically the same. The study of ancient and simple societies is done by Anthropology ,while on the basis of that sociology studies the wider and complex societies.

Anthropology has been divided in to three parts.

A-Physical Anthropology ,which deals with physical/bodily traits/features of early man and our primitive centuries back counterparts. with the help of that sociology try to know the reality of struggles among various groups.

B-Cultural Anthropology which investigates the cultural remains of early man an of the living cultures of some of the primitive counterparts. With the help of this sociology studies cultural heritage and tries to understand the changes occurred by it.

C-Social Anthropology deals with the institutions, behaviors and human relationships of primitives of the past and present. sociology also does scientific studies of human culture as a whole.

People may be obsessed with their weight due to societal pressures, media influence, and personal insecurities. The desire to fit into certain beauty standards, fear of being judged, and pursuit of health and fitness goals can also contribute to this obsession.

It's difficult to determine the first person to cheat as dishonesty has likely existed since the beginning of human history. Cheating can take many forms and has been observed in various contexts, from relationships to games to academic settings.
