Ants move small insects called aphids from plant to plant. the aphids are protected by the ants, while the ants feed on sugary honeydew produced by the aphids. what type of relationship is exampled in this scenario?

This is an example of mutualistic relationship.

Explanation:

This type of relationship occurs when two living beings of different species decide to cooperate in order to obtain a benefit from each other.

This is an example of the joint evolution of both organisms, who adapted to each other's environment and obtained something productive from it.

There are cases in which without the help of another organism, a living being would simply die.

There are two types of mutual relationship: the obligate and the facultative.

In the case of the obligate mutualistic relationship, without the help of an organism, another organism would die. Therefore it necessarily depends on its cooperation to exist.

In the case of the facultative one, both living beings obtain mutual benefits but they can quietly live without each other.

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!
