What is the illustration an example of?

a. oceanic-oceanic convergence boundary

b. transform boundary

c. divergent boundary

d. continental-continental convergence boundary

As given below.

Explanation:

1. The transform boundary is that of the San Andreas fault in California.

2. The divergent boundary is an example of the pacific ocean that is shrinking due to the opening of the Atlantic ocean.

3. The continental-continental convergent boundary is an example of the Indian plate and the Eurasian plate.

4. Oceanic-oceanic convergence boundary is an example of the Aleutian Islands in Alaska and the Japanese islands.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
