Which of the following is the function of a totipotent cell?

The best reason for the prolonged preservation of the body is that it was frozen in the cold temperature of the Alps shortly after he died and remained frozen until it was found.

Freezing can preserve a body by slowing down or stopping the decomposition process.

Choice A is not correct because the food that the person ate would not have contained toxins that killed the bacteria that would have otherwise destroyed the body.

Choice B is not correct because the arrow wound would not have caused blood to flow out of the body in a way that would have cleared enzymes that break down tissue from the body.

Choice D is not correct because ultraviolet rays at high altitude would not have caused all of the body’s molecules to be preserved.

The glomerulus is the main filtering unit of the kidney.

It is formed by a network of small blood vessels (capillaries) enclosed within a sac called the Bowman’s capsule.

The blood supply to the glomerulus is provided via the afferent arteriole.

The blood then flows through the capillary network, where it gets filtered, and then leaves the glomerulus via the efferent arteriole.

Choice B. Proximal tubule is not correct because it is where the ultrafiltrate collected in the Bowman’s space drains directly into.

Choice C. Distal tubule is not correct because it is not mentioned in relation to blood exiting the glomerulus.

Choice D. Afferent arteriole is not correct because it provides blood supply to the glomerulus.
