Answer:
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 <em>Trichomonas vaginalis, </em>an anaerobic, flagellated protozoan parasite and the causative agent of trichomoniasis. The number of genes of <em>T. vaginalis</em> is far bigger than the human cell, however the human complexity is far more advanced than the parasite organism.

Answer:
The solution is 0, 90 molal. See the explanation below, please
Explanation:
Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:
We calculate the weight of 1 mol of CaCl2
Weight Ca =40, 078 g
Weight Cl= 35, 453 g
Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g
110, 98 g ---1 mol
25 g---X= (25g x1 mol)/110, 98g= 0,23mol
250g solvent -----0,23 mol CaCl2 (the solute)
1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute
The solution is 0,90 molal
