Answer: A food web.
Explanation:
A food web has more diversity because a food chain only shows what each animal eats. A food web,however, shows everything you need to know and more.
The answer would be..... ribosomes!
Answer:
The nucleus tells other parts of the cell what to do
Explanation:
Answer:
Yes (but not how you think)
Explanation:
I'm assuming that you mean if nuclear fusion, where two atoms (in this case mostly hydrogen) fuse into one heavier atom, and release a lot of energy.
However, fusion happens when there is a tremendous amount of pressure or heat. This is found in the core
The 5 million degrees is found on the surface of the sun, but at the core, it is at 15 million degrees.
In addition, the pressure is so extreme that if forces atoms to become one, despite the fact they don't like being together (try finding 2 strong magnets and hold them so that they try to repel each other and try and make them touch, it's hard! Now imagine having to put a million of times the amount of strength!)
So, the sun is capable of nuclear fusion, but at the core, where it is 15 million degrees!
(fun fact: scientists are trying to build "mini-suns" called Fusion reactors to try and harvest the power of the sun!)
Answer:
The stratosphere
contains the ozone layer
,
is used by airplanes,
has strong, steady winds
, and
increases in temperature as altitude increases
.
Explanation:
The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.
It includes the ozone layer, which is at an altitude of about 20 km.
It has strong, steady winds that can reach as high as 220 km/h.
Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.
Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.
A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.
