Which of the following statements best describes the effect of climate on biome distribution?

#Unit 10. Ecological Principles
  1. Knowledge of annual temperature and precipitation is sufficient to predict which biome will be found in an area.
  2. Fluctuation of  environmental variables is  not  important if  areas  have  the  same  annual temperature and precipitation means.
  3. It is not only the average climate that is important in determining biome distribution, but also the pattern of climatic variation.
  4. Temperate forests, coniferous forests, and grasslands all have the same mean annual   temperatures and precipitation.

#Unit 8. Inheritance Biology

In each of the following cases, determine the consequences of a single crossover within the inverted region of a pair of homologous chromosomes with the gene order A B C D in one chromosome and a c b d in the other. There is a two situation of centromere for that gene. 

(A) Centromere is not included within the inversion.

(B) Centromere is included within the inversion

Following consequence are resulting are

I - The crossover chromatids consist of a dicentric and an acentric

II- One Cross over product is duplicated for the terminal region contain in A and deficient for the terminal region containing D

III- Both cross over products is monocentric

Following is correct combination for consequence?
