Answer:
When lymph nodes become infected, they usually increase in size, become tender, and may be felt in other areas of your body during a physical exam. Infections that spread to lymph nodes are usually caused by bacteria, a virus, or a fungus.
The two abiotic factors that make this possible include the
following:
<h3>What are Abiotic factors?</h3>
These refers to the non-living components of the ecosystem
and have various effects on different ecosystems being present
in the world.
Water and Temperature determine the types of crops and
animals which are found in the ecosystem. In Deserts for
example, the water is usually low with a corresponding high
temperature.

Answer:
Oxygenic photosynthesis
Explanation:
The process of oxygenic photosynthesis in which organisms use atmospheric carbon dioxide and fix it in the presence of sunlight into the organic nutrients led to the transition of anaerobic conditions on the primitive earth into the aerobic ones.
The oxygenic photosynthesis uses a water molecule as an electron donor. The water molecule is oxidized and oxygen gas is released as a by-product. This process led to the accumulation of oxygen in the atmosphere of the primitive earth.
The coast is warmer and better environment
Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.
The answer is RESPIRATION
