Eubacteria are bacteria which is different from archaea but both archaea and bacteria are considered to be in prokaryotes however they both are divided into two different domain that is bacteria and archaea.  

Bacteria and archaea are prokaryotes because they lack membrane-bound nucleus so their genetic material is scattered in the cytoplasm.

Assume a population is in Hardy-Weinberg equilibrium for the B gene, which has two alleles, B and b. In this population of 100,0
MArishka [77]

Answer:

160

Explanation:

If p = frequency of dominant allele and q = frequency of recessive allele according to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1

where p² = frequency of dominant homozygous genotype

q² = frequency of recessive homozygous genotype

2pq = frequency of heterozygous genotype

Here,

b = 4% = 0.04

bb = 0.04 * 0.04 = 0.0016

Number of individuals in population = 100000

Number of homozygous bb individuals = 0.0016 * 100000 = 160

mel-nik [20]

Answer:

pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
