Crossing over? That involves the random exchange of chromosomes.
Answer:
c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.
Explanation:
Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.
Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
A.) HCl+H2O=H3O+Cl
b.) NaCl+H2O=NaOH+HCl
c.)NaOH+HCl=NaCl+H2O
d.)HCl+NaOH=NaCl+H2O
Reactants: to the left side of equation
Product: to the right side of equation
H2O is water
HCl is hydrochloric acid
NaCl is sodium chloride aka table salt
NaOH is sodium hydroxide
