Describe the general trend of this graph

Biology
1 answer:
Mumz [18]2 years ago
5 0

Answer:

Point A (8000 BC): the human population was very small compared to nowadays

Point B (approx. 1350 AD): the human population underwent a drastic reduction in size

Point C (1750-2020 AD): the human population is undergoing an exponential growth

Explanation:

The emergence of agricultural practices during the early Holocene period 10000 thousand years ago enabled humans to remain in one place permanently (sedentism) and increased food resources, which had a positive impact on population growth. During this period (Point A), it is estimated that the world population was between one and ten million people. During 1345-1351 AC (point B), the world suffered the "Black Death", one of the most devastating pandemics that led to the death of up to 70–200 million people in North Africa, Europe and Asia, thereby causing a drastic reduction in human population. Moreover, scientific and technological advances in the last 250-270 years (i.e., since the industrial revolution to nowadays, point C) led to an exponential increase in the human population. Nowadays, the current world population is 7.6-7.8 billion people.

What is the difference between homeostasis and respiration​
Verizon [17]

Answer:

Abstract

Respiratory homeostasis is concerned with the regulation of a blood gas composition that is compatible with maintaining cellular homeostasis. Provided that the lung-capillary exchange barrier does not prevent the exchange of gases, then blood leaving the lung will have oxygen and carbon dioxide partial pressures that are similar to the average values found in the alveoli. Alveolar ventilation establishes these values. If blood gas composition, especially of carbon dioxide, moves outside the homeostatic range, the change is detected by chemoreceptors and respiratory responses are promoted which change alveolar ventilation, alter alveolar gas composition and so reverse the change. Ventilation therapies provide the means of artificially restoring alveolar gas composition. In general terms, they do this by raising the partial pressure of oxygen within the alveoli either by using oxygen-enriched gas mixtures, or by improving the ventilation of alveoli using positive pressure.
