Answer: B. both the pneumonic plague and the bubonic plague.
Explanation:
even if the technique for retrieving ancient DNA improves, you need to know what you’re searching for. There is no way now to search for an unknown hemorrhagic virus.
But the possibility that the Black Death could strike again should give scientists the incentive to keep trying. The similarity of the catastrophes in Athens, Constantinople and medieval Europe suggests that whatever the pathogen is, it comes out of hiding every few centuries. And the last outbreak was its fastest and most murderous. What would it do in the modern world? Maybe we should find it, before it finds us.
Options:
A. Radial
B. Parallel
C. Dendritic
D. Trellis
Answer:
A. Radial
Explanation:Radial pattern of a is the pattern of movement of the molecules making up the stream which causes the particles to divulge outwards from the center. This type of stream pattern causes patterns to spread out coming from the central region of the stream,this type of drainage pattern can be observed in the spoke of a wheel.
VOLCANIC ERUPTIONS,LACOLITHS AND DOMES ALL THESE GEOMORPHIC ACTIVITIES RADIATE OUTWARDS FROM A HIGH CENTER.
Answer:
According to the core accretion model, initially the dust particles and the interstellar gases were all combined together forming a huge cloud, that eventually gets cooled and these gases got concentrated and became gradually denser.
Due to the increasing density, this cloud got disintegrated under the action of gravity, thereby formed a proto-star. Due to the continuous fusion and gravity effects, a star formed and eventually got burst. It then formed the sun with a disk of substances and matter around it. This rotating disc in due course of time gave rise to the planets that exist today.
This is how the solar system originated according to the core accretion theory.
Hurricane Katrina formed over Southeastern Bahamas.
At that time it was still a tropical storm - not yet as devastating.
It then moved over Florida (around Florida is when it turned into a hurricane) and later into the Gulf of Mexico, where it gained strength and finally, it traveled towards the mainland of US.
The whole existance of Katrina, from its beginning until its dissipation lasted 8 days.
