Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.

Male cones grow near the<u> lower region</u> of the plant, while female cones are located near the<u> top of the tree.</u>
Sexual Reproduction in Gymnosperms :
The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.

D
Explanation:
Enzymes can only fit into the base it was made for.
We need to know the dominant and recessive traits of the noombats in order to answer this question. If both of them has yellow as the dominant trait, then green may be recessive. In that case there is a chance for them to have a green bellied child. Its impossible to tell the percentage though because we don't know enough about the animals.
