Answer:</h2>
This is basically because of lack of <u>mitochondria </u>in lower life forms.
<h2>
Explanation:</h2>
- Glycolysis is a Anaerobic(without oxygen) process in which glucose is breakdown in smaller forms without consuming oxygen.
- So glycolysis is the simplest sourse of energy production and hence it is commonly seen in both lower and higher organisms.
- However, immediately after finishing glycolysis, the cell will continue either aerobic or anaerobic respiration, this choice depends upon the presence of oxygen and mitochondria as the further process after glycolysis i.e kreb cycle(Citric acid cycle), electron transport chain (ETC) take place in mitochondria with the presence oxygen, and<u> lower organisms lack mitochondria</u> hence they cannot perform process after glycolysis.
Result: Smaller organisms obtain energy only by glycolysis.
The answer to your question is,
if the oxygen poor blood mixes back with oxygen rich blood, that means that oxygen poor blood is not going back to the lungs to swap CO2 (carbon dioxide) with O2 (oxygen), and this swapping is vital to tissue survival, since oxygen is what keeps your tissues, muscles, and organs alive. so if this blood mixed, ultimately your organs are not receiving enough oxygen and will become starved of it, this can kill you and lots of people every year get heart surgery because their atrium or ventricles in their heart rupture

During El Niño, the jet stream is oriented from west to east across the southern portion of the United States, making the region more susceptible to severe weather outbreaks.
Answer:
disaccharide
Explanation:
A disaccharide is a substance made up of two molecules of simple sugars (monosaccharides) linked to each other.
Monosaccharides include: glucose, fructose, galactose
Combining monosaccharides we get disaccharides:
sucrose = glucose + fructose
lactose = galactose + glucose
maltose = glucose + glucose
