Answer:
Their nephron loop is closely wrapped with vasa recta.
Explanation:
Cortical nephrons are located in the cortex.
They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
 
        
             
        
        
        
The temperature in an autoclave must reach 121° C in order for sterilization to occur.
<h3>Sterilization using autoclaves</h3>
Autoclaves are used to wet-sterilize materials in the laboratory.
In order for the sterilization to be effective, the temperature of the autoclave must reach 121° C. 
Also, substances to be sterilized must spend, at least, 30 minutes in the autoclave.

Answer:
India was a separate continent until 45 million years ago
Explanation:
India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.
