As the number of rabbits in a community goes up the number foxes in the same community goes up this is an example of what type of relationship a direct be in direct c cyclic d non-related

Answer:

As the number of rabbits in a community goes up the number foxes in the same community goes up. This is an example of a (A) Direct type of relationship

Explanation:

The relationship between a fox and a rabbit is a predator-prey relationship. In this kind of relationship, the predator eats the prey, i.e., one is hunted by the other. Other examples of such kind of relationship are zebra and lion, bear and fish where predator eats the prey.

Thus, if the count of rabbits in a community will increase more food will be available for the foxes. If they eat more food, they will grow better and hence their population would also increase. They have a direct connection.

a and c are the answeres

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!
