Decreased pH would increase the amount of oxygen unloaded by hemoglobin into peripheral tissues.
<h3>What is hemoglobin?</h3>
- The iron-containing oxygen-transporting metalloprotein known as hemoglobin.
- The abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. 
- The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
- Iron deficiency anemia is characterized by low hemoglobin that is brought on by low iron levels. 
- Low hemoglobin is most frequently caused by a diet that is inadequate in iron. 
- Low hemoglobin levels can cause headaches, exhaustion, and pale complexion. 
- Surgery, iron therapy, and iron supplementation are all options for treating low hemoglobin.
- Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs. 
- A low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia).

All cells don't have in common is an ability to colonize any environment on earth.
Cells- A cell's cytoplasm and nucleus are enclosed in a membrane, making it the smallest structural and functional component of an organism.
Environment- The natural habitat or natural world includes all living and non-living things that arise spontaneously, or in this case, without the use of artificial methods.
Living Object- A living thing is any creature or life form that demonstrates or possesses the characteristics of life or being alive.
Non-living things are inanimate items or forces that have the power to affect, shape, modify, and have an impact on the life of a living creature.

Shallow groove on the surface of the cortex is called sulcus.
Cortex means the outer layer of an inner organ. The outer layer of the cerebrum is called cerebral cortex, where cerebrum occupies the biggest part of the brain. A human being has four lobes of the cerebral cortex which include temporal lobe, parietal lobe, occipital lobe, and frontal lobe.
Cortex has six layers of different types of neurons which are responsible for higher information processing and thinking. Cerebral cortex controls general movement, behavioural reactions, perception and visceral functions. We term the grooved layer as the brain itself.Cerebral cortex consists of large amounts of sulci and gyri(sulcus and gyri in singular). The number of gyri correlates to the processing ability of the animal.A man has big gyri compared to a rat.
