Fertile soil is valuable because there is a limited supply. Less than one eighth of land on Earth has soil that are well suited for farming.
The thick, fertile soil of the prairies took many thousands of years to develop.
The two ways that the value of soil can be reduced is help use soil correctly, peanuts were once a corp to help soil, and still can be. The soil value recycle rocks and bedrock.
The value of soil is reduced when it loses its fertility and when topsoil is lost due to erosion. Soil can be conserved through contour plowing, conservation plowing and crop rotation. The thick mass of tough roots at the surface of the soil.
They Increase the surface area available for the absorption of nutrients
Answer:
given, mother and father are heterozygotes.
let, father has B blood group and mother has A blood group.
then their heterozygous genotypes are --
father = iB, iO and mother = iA, iO
punnett square will be,
iB iO
iA iA iB iA iO
iO iB iO iO iO
the genotypes of their progeny will be, iAiB , iAiO ,iBiO and iOiO
and phenotypes will be 3 are heterozygous and 1 is homozygous.
Answer:
Transamination reaction:
Transmaination reaction may be defined as a type of chemical reaction that involves the transfer of an amino group to the another keto acid fort the formation of new amino acid. The non essential amino acid can be easily converted to essential amino acid by this transmination reaction.
This reaction is important for the important mteabolic pathways of the body. The cofactor required for the transamination reaction is pyridoxal-5'-phosphate. This cofactor also works as a derivative of vitamin B6. This cofactor is converted to pyridoxamine-5'-phosphate during the reaction.
