Answer:
1:1
Explanation:
What is the concentration of H+ ions at a pH = 7?
⇒ 0.0000001 mol/L  
What is the concentration of OH– ions at a pH = 7?
⇒ 0.0000001 mol/L  
What is the ratio of H+ ions to OH– ions at a pH = 7?

Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
 
        
             
        
        
        
Answer:
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
- An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.  
- The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
