Answer:
The endosymbiotic theory deals with the origins of mitochondria and chloroplasts, two eukaryotic organelles that have bacteria characteristics. Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria, specifically alpha-proteobacteria and cyanobacteria, respectively.
Clinical death is the medical term for cessation of blood circulation and breathing, the two necessary criteria to sustain human and many other organisms' lives.
It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest.
Brain injuries start to accumulate almost immediately after Clinical Death.
Full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare.
Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored.
Although loss of function is almost immediate, there is no specific duration of clinical death at which the non-functioning brain clearly dies.
The most vulnerable cells in the brain, CA1 neurons of the hippocampus, are fatally injured by as little as 10 minutes without oxygen.
However, the injured cells do not actually die until hours after resuscitation.
Brain failure after clinical death is now known to be due to a complex series of processes called Reperfusion Iinjury that occur after blood circulation has been restored, especially processes that interfere with blood circulation during the recovery period.

Answer:
Circulating air is diverted due to the Earth's rotation. Instead of flowing in a straight line, air in the Northern Hemisphere deflects to the right, whereas in the Southern Hemisphere it deflects to the left, resulting in curved trajectories. The Coriolis effect is the name for this deflection.
Explanation:
Answer:
All of the above.
Explanation:
Monosaccharide may be defined as the sugars that are not further hydrolyzed or that do not give further sugars on hydrolysis. These monosaccharides are sweet in taste.
Glucose, galactose and fructose are monosaccharide sugars as they cannot be hydrolyzed further to give more sugars. These are colorless and water soluble sugars.
Thus, the correct answer is option (4).
White blood cells or WBCs are also known as leukocytes and these are the cells of the immune system. They serve as the soldiers inside our body that fight against infectious diseases and foreign invaders. WBCs are classified into different types. Some of them have multi-lobed nuclei, specifically, the neutrophils. It is the most abundant WBC in the body and they defend against bacterial and fungal infection. They have a multi-lobed nucleus, which consists of three to five lobes connected by slender strands. These multi-lobes are used for phagocytosis. Hope this answer helps.
