Answer:
I believe its D
Explanation:
Darwin said that a lot of evolution had to do with natural selection and that seems to be around the same thing.
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.
Answer:
I'm guesssing it's B? I did this a very long time ago( two weeks ago)
Explanation:
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
<span>Essentially, cohesion and adhesion are the "stickiness" that water molecules have for each other and for other substances. You can see this in the picture to the right. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion.</span>
