So gaseous exchange is the process of swapping one gas for another in the alveoli of the lungs.

3 reasons why it is important is because it gives the body the ability to eliminate carbon dioxide, replenish oxygen, and it is required for survival.

If this was to brief, please see further down for maybe more information.

Simple passive diffusion.

As they attempt to reach equilibrium between the partial pressure of each gas in the alveolus (a tiny air sac) and the partial pressure of each gas dissolved in pulmonary capillary blood entering the lung, O2 and CO2 readily diffuse through cellular membranes. As a result, almost equal amounts of oxygen and CO2 diffuse from the lung to the blood.

All mammals, birds, reptiles, and amphibians have hemoglobin in their blood. Oxygen replaces the carbon dioxide bound to the haemoglobin molecule as an animal breathes in. Haemoglobin has the valuable capacity to release carbon dioxide and absorb oxygen when the partial pressure of oxygen is higher, while doing the opposite when the partial pressure of oxygen is lower, as far as I can tell, and it has been 40 years since I took "A" level biology. Because air (typically) contains a significant excess of oxygen over carbon dioxide, blood moves to the lungs where it excretes carbon dioxide. Through the aerobic citric acid cycle, oxygen is reacted by metabolism in the body's tissues to produce carbon dioxide. Red blood cells give up oxygen to the tissues, thus when the oxygenated blood enters the tissues, carbon dioxide is transported from the tissue to the hemoglobin in the red blood cells.

Another way of saying it:

Diverse gases are naturally exchanged across a certain respiratory surface through a process known as gas trading. A functional framework for their commerce is essential since gases are constantly needed by cells and metabolic processes and given as a by-product. It is related to breathing in living things and to photosynthesis in plants as well. In order for cells to function properly when breathing, waste carbon dioxide (CO2) must be expelled, but during photosynthesis, CO2 enters plants and O 2 is released. Gas atoms move from a range of high fixation to low fixation as a result of dispersion down a focal angle, which essentially causes the trading of gases.

Thank you, I hope this helped.

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids

The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.

Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.

Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids.

Prions are misfolded proteins that have the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals. It is not known what causes a normal protein to misfold, but the resulting abnormal three-dimensional structure confers infectious properties by collapsing nearby protein molecules into the same shape.

The word prion is derived from the term, "proteinaceous infectious particle". In comparison to all other known infectious agents such as viroids, viruses, bacteria, fungi, and parasites, all of which contain nucleic acids (DNA, RNA, or both), the hypothesized role of a protein as an infectious agent stands in contrast.

Prion isoforms of the prion protein (PrP), whose specific function is uncertain, are hypothesized as the cause of transmissible spongiform encephalopathies (TSEs), including scrapie in sheep, chronic wasting disease (CWD) in deer, bovine spongiform encephalopathy (BSE) in cattle (commonly known as "mad cow disease") and Creutzfeldt–Jakob disease (CJD) in humans.

All known prion diseases in mammals affect the structure of the brain or other neural tissue; all are progressive, have no known effective treatment, and are always fatal. Until 2015, all known mammalian prion diseases were caused by the prion protein (PrP); however, in 2015 it was hypothesized that multiple system atrophy (MSA) was caused by a prion form of alpha-synuclein.

Prions are a type of intrinsically disordered protein, which change their conformation unless they are bound to a specific partner such as another protein. With a prion, two protein chains are stabilized if one binds to another in the same conformation. The probability of this happening is low, but once it does the combination of the two is very stable. Then more units can get added, making a sort of "fibril". Prions form abnormal aggregates of proteins called amyloids, which accumulate in infected tissue and are associated with tissue damage and cell death. Amyloids are also responsible for several other neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

No, humans haven't stopped evolving.

Extinction is the sole method that may effectively halt the evolution of any living being. Reducing and maintaining population size to a limited number of people can delay evolution. By reducing the introduction of new mutations into the population, this will reduce the amount of genetic variation that is lost through genetic drift. A population's capacity to evolve can be significantly reduced, but not entirely eliminated, by sustained limited population size because genetic variety is the foundation of all evolutionary change. But with humans, there is no doubt that this is not the case.

Since our population has been growing over the past 10,000 years, the contemporary human gene pool today holds a vast store of genetic diversity. Consequently, our capacity for evolution has never been greater. Indeed, instances of recent, positive selection created, not lessened by cultural change, have made use of this genetic variety. The distribution of genetic variation within and among local populations is fast changing, which is driving a significant evolutionary change in the human species. This transition is further fueled by a fundamental shift in the equilibrium between genetic drift and gene flow.

Even if our cultural innovations do decrease selection on a characteristic, that trait may nevertheless evolve in correlation with the evolution of another trait, frequently in a non-adaptive manner and occasionally in a moderately maladaptive manner. Humans will continue to evolve as long as there is a reproducing population.

But one thing is, pandas do have the ability to survive with bamboo.

But since bamboo comprises 99 percent of their food, although they also consume other plants and even meat, I highly doubt they could (whose make the remaining 1 percent ).

Because the gene T1R1 mutated some 4 million years ago, causing them to lose the ability to taste umami, giant pandas have come to rely significantly on bamboo (which is what makes meat tasty for omnivores and carnivores). The availability of bamboo trunks at the time coincided with their purported food source becoming increasingly limited, thus pandas became used to them and began to rely significantly on them, as they do now.

Deamination of amino acids in the excretory system will initially result in the formation of ammonia.

The NH2 (amino group) combines with a hydrogen ion (proton) to form ammonia (NH3).

Ammonia is very toxic and usually is excreted directly by marine animals. Terrestrial animals usually need to conserve water. Ammonia is converted to urea, a compound the body can tolerate at higher concentrations than ammonia.

Birds and insects secrete uric acid that they make through large energy expenditure but little water loss. Amphibians and mammals secrete urea that they form in their liver. Amino groups are turned into ammonia, which in turn is converted to urea, dumped into the blood and concentrated by the kidneys.

During deamination, enzymes remove the amino group as ammonia (NH3). Ammonia is toxic, even at low concentrations, and requires large amounts of water to flush it out of the body.

Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of glycolysis that is catalyzed by pyruvate kinase.

The tissues of some organs, including the brain, the eye, and the kidney, use glucose as their primary or only source of metabolic fuel. Glycogen stores become exhausted during a protracted fast or intense exercise, and glucose must be created from scratch to keep blood glucose levels stable. The process through which glucose is created from non-hexose precursors such glycerol, lactate, pyruvate, and glucogenic amino acids is known as gluconeogenesis.

Glycolysis is effectively reversed during glucose synthesis. However, gluconeogenesis makes use of four distinct enzymes to skip the three highly exergonic (and essentially irreversible) phases of glycolysis. The pyruvate carboxylase, PEP carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase enzymes are specific to gluconeogenesis. Gluconeogenesis can only take place in particular tissues because these enzymes are not found in all cell types. In humans, the liver and, to a lesser extent, the renal cortex are the primary locations for gluconeogenesis.
