"some people are tempted to say that the more genes an organism has, the more advanced it is. discuss this idea: what kinds of arguments support it and what arguments refute it.

The number of genes partially explains how an organism has evolved and how it gained complexity.

Explanation:

The number of genes of a bacteria versus an eucaryotic organism is quite distinct and so is their complexity. A prokaryotic organism like a bacteria has a set of genes necessary to exert their basic functions and the number of genes compared to a eucaryotic cell is 3-30 times smaller, which defines a direct correlation of number of genes and complexity. However if we consider only eucaryote organisms and their complexity there is no such direct correlation between number of genes and their complexity when, for example, we compare the number of genes of humans (approximately 18000) and the number of genes of the Trichomonas vaginalis, an anaerobic, flagellated protozoan parasite and the causative agent of trichomoniasis. The number of genes of T. vaginalis is far bigger than the human cell, however the human complexity is far more advanced than the parasite organism.

climate change and pollution

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!
