Groundwater is the body of water derived from percolation, contained within the soil, sub-soil and underlying rocks above an impermeable layer. The top layer of groundwater is known as the water table and it marks the permanent zone of saturation. Three appropriate ways for preserving groundwater are:
- Recycling groundwater for use
-Regulating the amount of groundwater used to water neighbourhood lawns
-Monitoring the chemicals used in fossil fuel extraction
Answer:
1/8 (12.5 %)
Explanation:
Cross: IAi X IAIB
F1: 1/4 IAIA 1/4 IAIB 1/4 IAi 1/4 IBi
Phenotypes:
- IAIA and IAi >> type A blood
- IBi >> type B blood
- IAIB >> type AB blood
Phenotypic frequency type A blood: 1/2 (i.e., 1/4 IAIA + 1/4 IAi) >>
Probability to have 3 offspring with type A blood: 1/2 x 1/2 x 1/2 = 1/8
The human ABO blood group is a system consisting of there different alleles: A, B, and O. This system is used in genetics as an example of codominance because both A and B alleles are expressed in heterozygous individuals (i.e., IAIB), whereas only the allele A is expressed in individuals that have A and O alleles (since O allele is recessive to the A and B alleles).
The answer to this question would be: The soil
Biological Organisms: Living things that are capable of reacting to stimuli, reproduction, growth, and homeostasis. Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi; or unicellular microorganisms such as a protists, bacteria, and archaea.
