The food cycle starts with the basic chemicals in the soil and ends up in producing complex compounds.

Explanation:

The process of food cycle starts from the soil where the carbon dioxide and water combines in the presence of sunlight to get converted into complex compounds.

These compounds are used by the plants itself and other animals. The animals use these complex compounds to get energy for sustaining their life.

The complex compounds are generally carbohydrates which is stored in the form of glycogen in the plants.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

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!
