They hypothesis states that Earth and its biological systems behave as a huge single entity and that this entity has closely controlled self-regulatory negative feedback loops that keep the conditions on the planet within boundaries that are favorable to life.
This hypothesis has it that living organisms interact with their inorganic environment to form a working and self-regulating, complex system which makes life and conditions for life on earth to continue favourably and perpetually
While looking at the figure, the union of the left and right brachiocephalic veins is Point A.
<h3>
What are brachiocephalic veins?</h3>
- The internal jugular vein and the subclavian vein join to form the brachiocephalic veins, also known as the innominate veins, which are substantial venous systems in the thorax.
- On the right side of the upper chest, the superior vena cava is formed by the union of the left and right brachiocephalic veins.
- These blood arteries are an essential part of the circulatory system in humans because they facilitate the removal of deoxygenated blood from the head and upper limbs.
- The internal jugular vein on the right and subclavian vein on the left combine to form the brachiocephalic veins. Both the vena cava and the brachiocephalic veins lack valves.

Explanation:
The goal of timing nitrogen (N) applications to corn is to supply adequate N when the crop needs it, without supplying excess that can potentially be lost. Because N reactions in the soil are closely linked to both temperature and moisture conditions, this goal is often hard to achieve.

Answer:
Batch culture is the most common laboratory-growth method in which bacterial growth is studied, but it is only one of many. The bacterial culture is incubated in a closed vessel with a single batch of medium.
