Answer:
According to the previous observational study it is possible to notice that thinning determined in great way the rate of trees that survived the fire. 
Explanation:
In general the trees that had been previously cut, were the ones that presented more resistance to the fire, while the trees that had not been thinned were the ones that were severely affected in the spreading conflagration. Reason why in comparison of these two samples, it would be possible to conclude that previously cutting down trees can survive better to the spreading fire.

Answer:
D. the 23rd pair of chromosomes
Explanation:
Humans have a total of 23 pairs of chromosomes. Out of a total of 23 pairs, 22 pairs are autosomes. Autosomes are the chromosomes that carry the genes for all the genetic traits but are not involved in the sex determination of the individuals. 
The 23rd pair of chromosomes in humans is of sex chromosomes as these chromosomes carry the genes to regulate the gender of the individuals. A human female has two copies of the X chromosome as sex chromosomes while human males have one X and one Y chromosome as their sex chromosomes. The Y chromosome carries "SRY" gene that codes for testes determining factor and regulates the development of testes in the embryo.
 
        
             
        
        
        
Lipophilic hormones,
intuitive as the name suggests, tend to dissolve
well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which
would affect their diffusion.  The carrier proteins are mainly the serum
albumins.
